Answer:
y=2/3x-5
Step-by-step explanation:
First, let's put this equation into slope-intercept form.
2x-3y=24
-3y=-2x+24
y=2/3x-8
For two lines to be parallel, they must have the same slope. Therefore our slope is 2/3.
Now, we must find b. To do that we can plug the y and the x in.
-7=2/3(-3)+b
-7=-2+b
-5=b
y=2/3x-5
Answer:
y = [tex]\frac{2}{3}[/tex]x - 5
Step-by-step explanation:
Points: (-3, -7)
Equation: 2x - 3y = 24
2x - 3y = 24
-3y = -2x + 24
y = [tex]\frac{2}{3}[/tex]x - 8
y = [tex]\frac{2}{3}[/tex]x + b
-7 = [tex]\frac{2}{3}[/tex] ( -3 ) + b
-7 = -2 + b
b = -5
y = [tex]\frac{2}{3}[/tex]x - 5

Kathy is a repair technician for a phone company. Each week, she receives a batch of phones that need repairs. The number of phones that she has left to fix at the end of each day can be estimated with the equation P=108−23d P = 108 − 23 d , where P is the number of phones left and d is the number of days she has worked that week. What is the meaning of the value 108 in this equation?
Answer:
What 108 represents here is that the total number of phones she has to fix each week is 108 phones
Step-by-step explanation:
The linear equation is
P = 108-23d
compare this with the general form;
y = mx + c
we have;
P = -23d + 108
We can see that 108 represents the y-intercept in this case
The x-value at the y-intercept is 0
So what this mean is that the number of phones she has to fix each week is 108
Elizabeth uses 34.95 ounces of granola for 15 servings of trail mix. If each serving contains the same amount of granola, how much granola is in each serving?
Answer:
2.33 ounces
Step-by-step explanation:
Given that:
Ounces of granola used = 34.95 ounces
Number of servings of trail mix = 15 servings
Since each serving contains the same amount of granola :
Amount of granola in each serving :
Ounces of granola used / Number of servings
34.95 / 15
= 2.33 ounces of granola per serving

Cory made 4,500g of candy He saved 1 kg to eat later. He divided the rest of the candy over 7 bowls to serve at his party.
How many grams of candy did Cory serve in each bowl?
Answer:
In each bowl, Cory put 500 grams of candy.
Step-by-step explanation:
You would do 4,500 - 1 (since he save a kilogram for himself), which would equal 3,500.
Then, you would do 3,500 divided by 7 (since there are 7 bowls and he wants to split the remaining candy evenly), which would equal 500.
Answer:
Cory served 500 grams of candy in each bowl.
Step-by-step explanation:
4,500 = 4.50 kilograms
4.50kg - 1.00kg = 3.50kg
3.50kg ÷ 7kg = 0.50kg
0.50kg = 500g

Which algebraic expression has like terms?
9n7 - 2n+3-4112
7 + 3n-3-672
7n+4n-3m-6n?
612 -4n4+6n-5772
Answer:
the answer is 612 -4n4+6n-5772
The expression that has like terms is (C) 7n+4n-3m-6n.
What is an expression?An expression can be as simple as a single number or variable, or it can be more complex, involving multiple operations and variables.
For example, the expression "3x + 4" contains the variable x, along with the constant values 3 and 4, and the operations of multiplication and addition.
Like terms are terms that have the same variables raised to the same powers.
In the first expression, 9n^7 and -2n have different powers of n, so they are not like terms. The constant term, -4112, is also not like any other term.
In the second expression, 3n and -3 are like terms, as they are both constants with no variables.
In the third expression, 7n, 4n, and -6n are all like terms because they all have the same variable, n, raised to the first power.
In the fourth expression, -4n^4 and 6n have different powers of n, so they are not like terms. The constant term, 612-5772=-5160, is also not like any other term.
Therefore, the expression that has like terms is (C) 7n+4n-3m-6n.

Nathaniel invests money in an account paying a simple interest of 6% per year. If he invests $90 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?
Answer:
95.40 total and 5.40 in intreset
Step-by-step explanation:
Answer:
A = $95.40
I = A - P = $5.40
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 90(1 + (0.06 × 1)) = 95.4
A = $95.40
The total amount accrued, principal plus interest, from simple interest on a principal of $90.00 at a rate of 6% per year for 1 years is $95.40.

Emilia needs at least $240 to buy new headphones. She has already saved $30. She earns $14 per car that she washes.
What is the least number of cars she can wash to buy the headphones?
a. 14x+30 ≥ 240
B. 14x+30 ≤ 240
C.30x+14 ≥ 240
D. 30x+14 ≤ 240
Explain your reasoning and solve equation:
Answer:
A is the correct equation to use when solving this problem
The least number of cars she can wash is 15
Step-by-step explanation:
If "'x" is the number of cars Emilia washes, then we would need to multiply that by the amount of money she gets from each car which means that "14x" needs to be in the equation somewhere. From this, we can already rule out C and D because those don't have "14x".
Also, since it says that Emilia needs at least $240, that would mean that she needs $240 or higher. Since the sign in equation A shows that, we know that it is equation A.
Since Emilia needs $240 or higher, the least number of cars she could wash would need to give her enough money to get to $240 when added to the $30 Emilia already has. We can multiply 14 by 15 to give us 210 which when added to the $30 she already has, will give us $240 which is the minimum amount of money she needs to buy new headphones.

A student measures the wingspans of 40 local dragonfly specimens selected at random. The sample mean is 6.8 centimeters with a margin of error of 0.9 centimeters. Based on this information, what are plausible values for the mean wingspans of the population of local dragonflies?
Explain or show your reasoning.
Answer:
6.8 - 0.9 = 5.9
Step-by-step explanation:
5.9 is the only average that seemed reasonable. Hope I helped.
According to the margin of error, it is found that plausible values for the mean wingspans of the population of local dragonflies are between 5.9 and 7.7 cm.
What is the margin of error of a measure?It is about how much the measure can plausibly differ from the sample mean.
In this problem, considering the sample mean of 6.8 cm and the margin of error of 0.9 cm, the bounds of plausible values are given by:
6.8 cm - 0.9 cm = 5.9 cm.6.8 cm + 0.9 cm = 7.7 cm.More can be learned about margin of error at https://brainly.com/question/25779324

1.red sky in the afternoon sunset
2. rainbows only appear after the rain
3. there's a pot of gold at the end of the rainbow
1.) As the sun light travels along path through as atmosphere to reach our eyes, the blue light has been mostly remove living mostly red and yellow light remain since red light waves are scattered the list by atmospheric gas molecules
2.) Rainbows are formed when it’s misty or spray the sky with water. It’s not solely just from after a rain; you only need water that can act at as prism and light to shine to create a rainbow.
3.) Having gold at the end of rainbow is just a myth since you can never reach the end of the rainbow. A rainbow is caused by dispersion of light in water droplet which is why they occur when sun comes out after rain.

What are the area and perimeter of square TUVW?
Area=
Perimeter=
Answer:
Area: 196
Perimeter: 56
Step-by-step explanation:
1. Pick a side for both length and height and count the distance between the two coordinates (for example VU and UT)
VU = 14
UT= 14
Also important to note here that you don't even need to count the distance for both because since it's a square, all the sides are the same. Only did this to make it easier to understand the next step.
2. Since it's a square, as I said before, all sides are the same. So, you can go ahead and mark WT and VW as 14 as well.
3. To get the area, use the formula base times height.
14 x 14 = 196
4. For perimeter, simply add up all the sides (or multiply 14 by 4 since all are the same)
14+14+14+14=56
if x2=18x+y and y2=18y+x, then find the value of root
Answer:
[tex]\sqrt{x^2+y^2+1}=18[/tex]
Step-by-step explanation:
We are given:
[tex]x^2=18x+y\qquad\qquad[1][/tex]
[tex]y^2=18y+x\qquad\qquad[2][/tex]
Subtracting [1] and [2]:
[tex]x^2-y^2=18x+y-(18y+x)[/tex]
Operating:
[tex]x^2-y^2=18x+y-18y-x[/tex]
Recall:
[tex]x^2-y^2=(x-y)(x+y)[/tex]
Substituting:
[tex](x-y)(x+y)=18x+y-18y-x[/tex]
Rearranging:
[tex](x-y)(x+y)=18x-18y-(x-y)[/tex]
[tex](x-y)(x+y)=18(x-y)-(x-y)[/tex]
Dividing by x-y (recall x≠y):
[tex]x+y=18-1=17[/tex]
[tex]x+y=17\qquad[3][/tex]
Now we add [1] and [2]:
[tex]x^2+y^2=18x+y+18y+x[/tex]
Rearranging:
[tex]x^2+y^2=18x+18y+x+y[/tex]
[tex]x^2+y^2=18(x+y)+(x+y)[/tex]
[tex]x^2+y^2=19(x+y)[/tex]
Substituting from [3]
[tex]x^2+y^2=19*17=323[/tex]
Adding 1:
[tex]x^2+y^2+1=324[/tex]
Taking the square root:
[tex]\sqrt{x^2+y^2+1}=\sqrt{324}=18[/tex]
Thus:
[tex]\mathbf{\sqrt{x^2+y^2+1}=18}[/tex]
