Using the equation y = kx, we need to find k for that data
150 = k(1250)
150/1250 = k
0.12 = k
You can confirm that by doing the same with the second row, but I won’t put that here. It’s the same.
Dollars/kilowatt-hour is the label for the k of each equation (0.12, 0.15). We calculated dollars divided by (per) kWh.
Company P is less expensive than company M, because 0.12 < 0.15.
We need to buy 2,375 kWh of electricity from company P. The equation y = kx applies, where y is unknown, k = 0.12, and x = 2,375
y = (0.12)(2375)
y = $285

5.Regarding the equations below. What is the value of x?
5x + 2y = 4
x – 3y = –23
Answers
Answer:
x=−2
y=7
Step-by-step explanation:
5x+2y=4
x−3y=−23
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
5x+2y=4,x−3y=−23
To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.
5x+2y=4,5x+5(−3)y=5(−23)
Simplify.
5x+2y=4,5x−15y=−115
Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.
5x−5x+2y+15y=4+115
Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.
2y+15y=4+115
Add 2y to 15y.
17y=4+115
Add 4 to 115.
17y=119
Divide both sides by 17.
y=7
Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.
x−3×7=−23
Multiply −3 times 7.
x−21=−23
Add 21 to both sides of the equation.
x=−2
The system is now solved.
x=−2,y=7

In each of the following graphs, the two given polygons are similar. Write precisely a single dilation (coordinates of center and coefficient) by which the image (labeled with primed letters) was obtained. Will Give Brainiest!!!!!
Answers
Answer:
Center: (0,0) coefficient: [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The side of the smaller polygon is 1/3 the size of the larger one, and that is why the coefficient is 1/3.
Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.
What is dilation?Dilation is the increase or decrease in the size of a figure by a scale factor of k, thereby creating an image.
From the diagram:
Scale factor = N'P' / NP = 2/6 = 1/3
Center = (0, 0)
Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.

The longest angle is opposite to the longest side in a triangle. The same goes for the shortest and middle angles.
B is opposite to the 57 degree angle, the shortest angle, so it’s the shortest side. A is opposite to the 59 degree angle, so it is the second shortest side. C is opposite to the 64 degree angle, the largest angle, so it’s the longest side.

So in this equation we have to solve using PEMDAS, or parentheses, exponents, multiplication, division, addition, then subtraction, going from left to right. So first, i deal with whats in the parentheses, but since it cannot be subtracted, I next go on to the next step. Since there are no exponents, our next step is to multiply or distribute 2 into (-3-6x). In other words, i multiply 2 by -3 and 2 by -6x. This is going to be -6 -12x. After that, i add and subtract common factors, so 3x-12x is -9x, and -4-6 is -10. This leaves us with -9x-10=0. I add 10 to each side according to addition property of equality. Thus, the equation is -9x=-10. Divide both sides by -9, by the division property of equality, and u get 10/9. If you want a decimal answer, type it into a calculator.

Answers
Answer:
∠b=35
Step-by-step explanation:
Hello There!
Complementary angles add up to equal 90
so to find the measure of angle B we subtract the given angle from 90
90-55=35
so we can conclude that ∠b = 35
