How do i get the equation: 2x+3y=1,470 to slope intercept form. please provide steps :))
Answer:
y= -2 +490
3
Step-by-step explanation:
y=mx+b is the slope intercept form of a like where m is the slope and b is the y intercept
Answer:
y=-2/3x+490
Step-by-step explanation:
As we know the formula for slope intercept form would be y=mx+b
therefore we arrange our numbers in the following manner:
First subtract 2x from 2x so it'll be like 2x-2x and they cancel each other out so keep that in mind, now what you do on one side you have to do it on the other side as well therefore you'll putt -2x on the other side now we are left our equation as 3y=1,470-2x
Second, as we want our form to be slope intercept form I believe that y should be by it self and to do that you need to divide 3 from y, now remember that what you do on one side you have to do it on the other. So you'll divide 3 from all the numbers on the other side. Now on the other side we have 1,470-2x so we will divide 1,470/3=490 and -2x/3 now we are left with y= 490-2/3x ( i left -2/3x as that because dividing makes it a decimal and a decimal and the fraction has the same value so I just left it as a fraction)
Thirdly, sense we want our equation as a slope intercept form we will need to rearange our equation which we need to keep in mind the form which is y=mx+b so that makes it to our answer y=-2/3x+490
Hope this helps :)

The Circle Problem Draw a circle.You have only 3 lines. Divide the circle into 7 pieces.
In your own words, explain how to solve this problem. To attain maximum credit please include any websites used for references. Your reflection should include complete sentences and paragraphs.
Answer:
Draw a x then place a horizontal line to cut the highest quarter piece in half
A circle with 7 pieces is given below.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
And the general formula of the circle,
(x – h)²+ (y - k)² = r²,
where (h, k) is the center and r is the radius of the circle.
Here is one way to divide a circle into 7 pieces using only 3 lines:
Draw a horizontal line across the middle of the circle to create two equal halves.
Draw a vertical line that intersects the horizontal line at the center of the circle.
Draw a diagonal line from the top of the circle to the bottom, passing through the center point.
This should create 7 pieces in the circle: two halves, four quarters, and one central piece that is shaped like a kite.
Therefore, the diagram of the image is given below.

Consider this right triangle. R 9 55° Q P Enter the length of RQ, to the nearest tenth.
Answer:
RQ = 7.4
Step-by-step explanation:
From the right triangle PQR,
m∠Q = 90°
m∠P = 55°
Hypotenuse PR = 9
By applying sine rule in the given triangle,
Sin(55°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
0.819152 = [tex]\frac{\text{RQ}}{\text{PR}}[/tex]
0.819152 = [tex]\frac{RQ}{9}[/tex]
RQ = 9×0.819152
RQ = 7.37

Hey there! Let's answer each part of this question in order.
Part aIf Pedro withdrew [tex]\$35[/tex] per week, his change in balance could be represented as [tex]-35x[/tex] since [tex]x[/tex] is the number of weeks. Add this to his initial balance of [tex]\$710[/tex] to get the first answer:
[tex]\huge\boxed{710-35x}[/tex]
Part bThe same concepts can be applied to solve the next part. Maria started off with [tex]\$570[/tex] in her account and withdrew [tex]\$25[/tex] each week. Apply the same process from the first part to get the second answer:
[tex]\huge\boxed{570-25x}[/tex]
Part cWrite an equationFor the last part, we need to find the value of [tex]x[/tex] that makes the expressions we made in the first two parts equal to each other, so start by making them into an equation.
[tex]\huge\boxed{710-35x=570-25x}[/tex]
Solve the equationNow we need to solve this equation. Start by bringing the constants to the right and the variables to the left.
Keep in mind that when you move a term to the other side of the equation, you need to change its sign, as you are adding or subtracting the same number from both sides of the equation.
[tex]\begin{aligned}710-35x&=570-25x\\-35x&=570-25x-710\\-35x+25x&=570-710\end{aligned}[/tex]
Now, combine the like terms with addition and subtraction.
[tex]\begin{aligned}-35x+25x&=570-710\\-10x&=-140\end{aligned}[/tex]
Finally, divide both sides of the equation by [tex]-10[/tex] to fully isolate the variable and find the final answer.
[tex]\begin{aligned}-10x&=-140\\x&=14\ \text{(weeks)}\end{aligned}[/tex]
[tex]\huge\boxed{14\ \text{weeks}}[/tex]
Check your answerWe can also check our answer by substituting the final answer back into each expression, simplifying, and making sure the answers are equal.
[tex]\begin{array}{l|l}710-35x&570-25x\\710-35*14&570-25*14\\710-490&570-350\\220&220\end{array}[/tex]
Since the expressions are equivalent, we know that Pedro's balance is the same as Maria's balance after [tex]14[/tex] weeks.
En mi familia tres primos cumplimos años el mismo día y la abuela quiere regalarnos dinero a los tres para que nos compremos lo que deseamos.Sin embargo,a cada uno nos gustan cosas de diferentes precios,yo deseo gastar el dinero en un día de salida al cine y comer en algún restaurante,para lo cual mi abuela me dio 2 veces mas que el dinero que le dio a reiner;mientras que julio quiere un reloj y recibió cuatro veces lo que recibió reiner.El más pequeño de todos es reiner,el quiere dos juegos de xbox ¿que cantidad de dinero nos dio la abuela a cada uno por los cumpleaños, si en total por los tres sumaron $6000?
Answer:
Tu recibiste = $1714,3
Reiner recibió = $857,1
Julio recibió = $3428,6
Step-by-step explanation:
Podemos encontrar el dinero que recibieron todos mediante la siguiente expresión:
[tex] A + R + C = 6000 [/tex]
Dado que A recibió 2 veces más que el dinero que Reiner y C recibió 4 veces lo que recibió Reiner, entonces:
[tex] 2R + R + 4R = 6000 [/tex]
[tex] R = \frac{6000}{7} = 857,1 [/tex]
Ahora, podemos encontar cuanto recbieron los otros dos primos:
[tex] A = 2R = 2*\frac{6000}{7} = \frac{12000}{7} = 1714,3 [/tex]
[tex] C = 4R = 4*\frac{6000}{7} = \frac{24000}{7} = 3428,6 [/tex]
Por lo tanto, tu recibiste $1714,3, Reiner recibió $857,1 y Julio recibió $3428,6.

Your total cost C to skate at Skate Days is a $2 skate rental plus an additional $3.25 for each hour Chat
you skate.
Write a function rule to represent the situation.
19
Is this situation continuous or discrete? Explain your reasoning.
Create a sign that Skate Days can display at the counter that tells people how much it will cost
for each hour they skate (include 1-5 hours on your sign)
Skate City has free skate rental but charges $4 for each hour.
Which skating rink would you choose to go to?
Why did you make that choice? Use mathematical reasoning to support your answer. Lo
Answer:
The cost is a fixed $2, plus $3.25 for any additional hour.
Then if you rent it for x hours, the cost is:
c(x) = $2 + $3.25*x
Is this situation continuous or discrete?
Yes, it is discrete, because x is "the number of hours"
so if you rent it for 1.30 hours, they will say "ok, this is equivalent to two hours".
This means that while the values of x are continuous, the possible costs are:
{$2, $2 + $3.25, $2 + 2*$3.25, ....}
Which is a discrete set.
Then the sign for 1 to 5 hours will be:
1 hour ---------- $2 + $3.25 = $5.25
2 hours -------- $2 + 2*$3.25 = $8.50
3 hours--------- $2 + 3*$3.25 = $11.75
4 hours--------- $2 + 4*$3.25 = $15
5 hours -------- $2 + 5*$3.25 = $18.25
In the other park the cost is only $4 for each hour (no fixed cost) then the total cost for x hours is:
c(x) = $4*x
Now, which option is better?
If we look at the costs for different numbers of hours for this other equation, we have:
1 hour ----- $4
2 hours ---- 2*$4 = $8
3 hours ----- 3*$4 = $12
4 hours ------ 4*$4 = $16
Then: if you want to skate 2 hours or less, Skate City is cheaper, if you want to skate more than that, kate Days is cheaper.
This happens because the first one has a smaller slope, meaning that is larger at first, but as x grows the price does not grow as much as in Skate City
A kite has a perimeter of 108 feet. One of the longer sides measures 30 feet. What are the lengths of the other three sides?

30 feet, 48 feet, 48 feet
Answer:
24 feet, 24 feet, 30 feet
Step-by-step explanation:
edge 2020
The given perimeter of 108 feet, and length of the longer side of 30 feet,
gives the following length of the other sides;
24 feet, 24 feet, 30 feetWhich method can be used to find the lengths of the sides?A kite has two pairs of adjacent sides having equal length
Let x represent the length of one of the shorter sides, we have;
The perimeter of the kite = 2 × x + 2 × 30 = 108Which gives;
x = (108 - 2 × 30) ÷ 2 = 24
The length of one of the short side, x = 24 feet
The kite has 2 sides of length 24 feet and 2 sides of length 30 feet
The lengths of the other sides are therefore;

Civil engineers are designing a section of road that is going to dip below sea level. The road's curve can be modeled by the equation y = 0.00005x2 - 0.06x, where x is the horizontal distance in feet between the points where the road is at sea level and y is the elevation. The engineers want to put stop signs at the locations where the elevation the road is equal to sea level. At which horizontal distances will they place the stop signs?
Answer:
1200feet
Step-by-step explanation:
Given the the road's curve elevation modeled by the equation
y = 0.00005x^2 - 0.06x,
x is the horizontal distance in feet between the points where the road is at sea level and;
y is the elevation
The elevation the road is equal to sea level when y = 0
Substitute y = 0 into the equation and calculate x;
0 = 0.00005x^2 - 0.06x
0.06x = 0.00005x^2
0.06 = 0.00005x
x = 0.06/0.00005
x = 1200 ft
Hence they will place the stop sign at a horizontal distance of 1200feet
