Answer:
y = 4x - 2
Step-by-step explanation:
First, let's find the slope of the equation. If you take a look at the table of values, as x goes up by 1, y goes up by 4. This means the slope is 4. To find the y-intercept, look where x = 0. When x = 0, y = -2.
In conclusion, the equation is:
y = 4x - 2

ivy bought 10 packs of cups for her holiday party. a pack of medium cups costs $1.80 and a pack of large cups costs $2.40. she paid a total of $21.60. how many packs of each size cup did she buy?
Answer:
4 packs of medium cups and 6 packs of large cups
Step-by-step explanation:
1.80x + 2.40y = 21.60
1.80(4) + 2.40(6) = 21.60
7.2 + 14.4 = 21.60
21.60 = 21.60
Answer:
Ivy bought 4 packs of medium cups, and 6 packs of large cups.
Step-by-step explanation:
To solve this problem, we will have to use a system of equations. Our first equation will represent the cups, and our second equation the costs.
Let [tex]m[/tex] equal medium cups.
Let [tex]l[/tex] equal large cups.
[tex]m+l=10[/tex]
[tex]1.80m+2.40l=21.60[/tex]
Let's use substitution to solve this system.
Subtract [tex]l[/tex] from both sides of the first equation:
[tex]m=10-l[/tex]
Let's substitute [tex]10-l[/tex] into the second equation for [tex]m[/tex]:
[tex]1.80(10-l)+2.40l=21.60[/tex]
Distribute [tex]1.80[/tex] into [tex](10-l)[/tex]:
[tex]18-1.80l+2.40l=21.60[/tex]
Combine like terms:
[tex]18+0.6l=21.60[/tex]
Subtract [tex]18[/tex] from both sides of the equation:
[tex]-0.6l=3.60[/tex]
Divide by the coefficient of [tex]l[/tex], which is [tex]0.6[/tex]:
[tex]l=6[/tex]
Ivy bought 6 packs of large cups.
_
Let's substitute [tex]6[/tex] into the first equation to find the number of medium cup packs:
[tex]m+6=10[/tex]
Subtract [tex]6[/tex] from both sides of the equation:
[tex]m=4[/tex]
Ivy bought 4 packs of medium cups.
_
We can check our work 2 ways; by substituting our solved values into the initial equations.
1st Equation Check:
[tex](4)+(6)=10[/tex]
[tex]10=10[/tex]
2nd Equation Check:
[tex]1.80(4)+2.40(6)=21.60[/tex]
[tex]7.2+14.4=21.60[/tex]
[tex]21.60=21.60[/tex]

EDGE 2020 The average monthly high temperatures for Phoenix, Arizona from the years 1981-2010 are shown in the table below, with the value 1 representing the month of January, and the value of 12 representing the month of December. Complete the following steps to model the curve using the sine function.
a. Make a scatterplot of the data.
b. What is the minimum temperature in the data set?
c. What is the maximum temperature in the data set?
d. What is the vertical shift, k, for the data set?
e. What is the amplitude, a, for the data set?
f. What is the period and frequency factor for the data set?
g. What is the phase shift for the data set?
h. Write an equation using the sine function that models this data set.
i. When would you expect the temperature in Phoenix to be 82°?
Answer:
a. Please find attached the required scatter plot
b. The minimum temperature in the data set is 67°F
c. The maximum temperature in the data set is 106°F
d. The vertical shift for the data set is 67°F
e. The amplitude 19.5 °F
f. The period is 12 months, the frequency = 1/12 months
h. The sine function equation that models the data set is 19.5·sin(π·t/6 - π/2) + 86.5
i. After the second and before the third month or after the ninth and before the 10th month
Step-by-step explanation:
The equation for the sinusoidal variation of temperature with time can be presented as follows;
y = A·sin(Bt + C) + D
Where;
A = The amplitude = (The Maximum value - The minimum value)/2
The amplitude = (106 - 67)/2 = 19.5°F
B = 2·π/(The period) = 2·π/12 = π/6
t = The time in months
C = The phase shift = -π/2
D = The midline = (The Maximum value + The minimum value)/2 = (106 + 67)/2 = 86.5 °F
The equation that models the data = 19.5·sin(π·t/6 - π/2) + 86.5
When the temperature is 82°, we have;
82 = 19.5·sin(π·t/6 - π/2) + 86.5
82 - 86.5 = 19.5·sin(π·t/6 - π/2)
-4.5°F = 19.5·sin(π·t/6 - π/2)
sin⁻¹(-4.5/12) = π·t/6 - π/2
-0.3844 = π·t/6 - π/2
-0.2329 = π·t/6 - π/2
t = 2.55 or 12 - 2.55 = 9.44
Which is either after the second and before the third month or after the ninth and before the 10th month.
In this exercise we have to use the function knowledge to calculate the temperature that is requested in each alternative, so we have to:
a. The answer is in the scatter plot
b. The minimum is 67°F
c. The maximum is 106°F
d. The vertical shift is 67°F
e. The amplitude 19.5 °F
f. The frequency is 1/12 months and the period is 12.
h. The sine function equation that models the data set is [tex]19.5sin(\pi t/6 - \pi /2) + 86.5[/tex]
i. After the second and before the third month or after the ninth and before the 10th month
The equation for the sinusoidal variation of temperature with time can be presented as follows;
[tex]y = Asin(Bt + C) + D[/tex]
Where;
A = [tex](106 - 67)/2 = 19.5\°F[/tex]B = [tex]2\pi /(T) = 2\pi/12 = \pi/6[/tex]t = 12 C = [tex]\pi/2[/tex]D = [tex](106 + 67)/2 = 86.5 \°F[/tex]The equation that models the data is given by:
[tex]19.5sin(\pi t/6 - \pi/2) + 86.5[/tex]
When the temperature is 82°, we have;
[tex]82 = 19.5sin(\pi t/6 - \pi/2) + 86.5\\82 - 86.5 = 19.5sin(\pi t/6 - \pi/2)\\-4.5\°F = 19.5sin(\pi t/6 - \pi/2)\\sin^{-1}(-4.5/12) = \pi t/6 - \pi /2\\-0.3844 = \pi t/6 - \pi /2 \\-0.2329 = \pi t/6 - \pi /2\\t = 2.55 \ or \ 9.44[/tex]
Which is either after the second and before the third month or after the ninth and before the 10th month.

Answer:
Add -3+8
Step-by-step explanation:
You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].

Answer:
Use PEMDAS
Step-by-step explanation:
Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D

what is the equivalent ratio to 1:5?
Answer:
2:10; 3:15; 4:20; etc
Step-by-step explanation:
The equivalent rations can be found by finding a common factor for 1:5. Examples include 2:10, 3:15, 4:20, etc. All of these have a common factor and thus are the equivalent ratios to 1:5.
The equivalent ratio to 1:5 is 2:10,3:15,4:20, etc.
Given that,
We need to find the equivalent ratio to 1:5.Here the equivalent ratio could be determined by measuring the common factor.
Like 2:10 = 1:5
3:15 = 1:5
4:20 = 1:5
Therefore we can conclude that the equivalent ratio to 1:5 is 2:10,3:15,4:20, etc.

Graph a line with a slope of -5 that contains the point (-3,-4)
We want to graph a line with a slope of -5 that contains the point (-3, -4), the graph can be seen at the end.
Getting the equation:
We first need to get the equation of the line that we must graph.
The general line equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
Here we know that the slope must be -5, so we have:
y = -5*x + b
And we know that it must contain the point (-3, -4), then we can replace these values for x and y in the equation and solve it for b:
-4 = -5*-3 + b
-4 = 15 + b
-4 - 15 = b
-19 = b
Then the linear equation is:
y = -5*x - 19
To graph this you just need to find two points on the line and then connect them with a line, we already know one (-3, -4). To get another we can evaluate the equation in any value of x, for example with x = 0 we get:
y = -5*0 - 19
y = -19
Then the other point is (0, -19)
With these two points you will get the graph below:

If you are given the length of the hypotenuse and one leg, does it matter whether you solve for a or b? Explain.
Answer:
No because [tex]a^2 + b^2 = b^2 + a^2[/tex]
Step-by-step explanation:
No it does not matter if you were given a or b because with the equation a²+b²=c² as long as you can substitute in two values you can solve for the unknown value. For example if you had triangle STU having hypotenuse as 41 and value a as 9 you would substitute in the values resulting in the equation 9²+b²=41² then you would solve the exponents 81+b²=1681 then you would subtract 81 having the equation now as b²=1600 then you would √b²=√1600 resulting in
b=40
you could solve that equation the same way if you had b=40 and c=42

Answer:
m∠EBC = 62°
m∠EBA = 124°
m∠CBA = 62°
Step-by-step explanation:
It's given in the question that a line BC bisects angle EBA.
And m∠EBC = 62°
Since, BC is an angle bisector of ∠EBC,
Therefore, m∠EBC = m∠CBA = 62°
Since, m∠EBA = 2(m∠EBC)
Therefore, m∠EBA = 2 × 62° = 124°
Fred bought a burger and two orders of fries for $6.50. One order of fries is $1.50. How much was the burger?
Answer:
Step-by-step explanation:
The burger was 3 dollars and 50 cents . The two order of fries were 3 dollars
Answer:
$3.50
Step-by-step explanation:
first you take the amounts you do know, which is the total amount and the cost of one order of fries.
you know he got 2 fries, so thats 1.50 times 2.
1.50 x 2 = 3.00
then you subtract that from the total
6.50 - 3.00 and you're left with 3.50
In the function above, the slope will be multiplied by -9, and the y-value of the y-intercept will be increased by 2 units. Which of the following graphs best represents the new function? if u need the choice ill give them to u
Answer:
Step-by-step explanation:
I can give you the key points to look for without the graph. You'll have to do that.
New y intercept
The intercept increases by 2. Currently it is 2. The new y intercept is 2 + 2 = 4
The new Slope
The slope is multiplied by - 9. Currently it is (y2-y1)/(x2 - x1) = (2-0)/(0-6) = 2/-6= - 1/3
This is multiplied by - 9
-9*(-1/3) = 3
New equation
y = 3x + 4
x intercept.
The x intercept occurs when y = 0.
0 = 3x + 4
-4 = 3x
-4/3 = x
