YOUR ANSWER IS (-18,9)
skelet666 [1.2K]3 years ago

Answer:

90/13, 45/13

Step-by-step explanation:

- 2 = x \\ 7x + 9y =  - 45 \\  \\ 7 \times ( - 2)y + 9y =  - 45 \\ y = 9 \\  \\ 7x + 9 \times 9 =  - 45 \\ x =  - 18 \\ (x.y) =  (- 18.9) \\  \\

Simplify:

- 2 \times 9 =  - 18 \\  7 \times ( - 18) + 9  \times 9 =  - 45 \\  - 18 =  - 18 \\  - 45 =  - 45

A line passes through the given points. write an equation for the line in point-slope form. then rewrite the equation in slope i
rodikova [14]

#1 first we need to solve for slope which is y2-y1/x2-x1

plug in the coordinates and get 1-6/5-(-2) which makes our slope -5/7

then use the equation for point slope form which is:

y-y1=m(x-x1)

then plug in one of the coordinates, I'll use (-2,6), now we have

y-6=-5/7(x+2)

now to make this slope intercept, we just have to solve

y-6=-5/7x-10/7

y=-5/7x+4 4/7

repeat all these steps for 2 and 3

#2: slope = -13/5

plug it in to point slope and get: y+8=-13/5(x-3)

slope intercept:

y+8= -13/5x + 39/5

y= -13/5x -1/5

#3: slope = 3/4

point slope form: y-2=3/4(x-3)

slope intercept: y-2=3/4x-9/4 --> y=3/4x-1/4

The question is shown in the picture
Masteriza [31]
20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.

Now lets work this out.
20 + 25x =282.50
25x = 262.50   (subtract both sides by 2 to get the x's alone)
x = 10.5    (divide both sides by 25 to get just x)
x = 10.5 hours

So the answer is A.
