Step-by-step explanation:

you need to substitute the x in (7x +2y=13) with (x=2y+11) to solve it

y =  - 4

Step by step explanation:

Equation 1:

x = 2y + 11

Equation 2:

7x + 2y = 13

Put the value of X from equation 1 into equation 2.

7(2y + 11) + 2y = 13

Solve the brackets.

14y + 77 + 2y = 13

Simplify.

16y + 77 = 13

Send 77 to the other side.

16y= 13 - 77

16y =  - 64

Send 16 to the other side.

y =    - \frac{64}{16}

Answer:

y =  - 4

Hope this helped!

Can someone please help? A ferris wheel is drawn on a coordinate plane so that the first car is located at the point ​(0​,10​).
Ugo [173]

Answer:

(10,0)

Step-by-step explanation:

When it comes to rotations by 90 degrees or 270 degrees, you just have to switch the order of x- and y- coordinates. Then find the sign by considering which quadrant will it be. In this case, it is originally on the positive y-axis and now it would be +ve x-axis.

what equation would represent the same linear relationship for the points (40,80) (80,115) (120,140) (160,165)
tiny-mole [99]
You can use the formula y1-y2=m(x1-x2)

to find m, you just do (y2-y1)/(x2-x1) so....

(115-80)/(80-40)= 35/40= 7/8

then plug it into the point slope equation:

y-115=7/8(x-80)

y-115=7/8x-70
y= 7/8 x + 45
