Answer: r = 11

Step-by-step explanation:

We know that the point (-2, r) lies on the graph of:

2*x + y = 7.

Then, if we that point is on the graph of the equation, we can replace the values and we will have:

2*(-2) + r = 7

and now we solve this for r-

-4 + r = 7

r = 7 + 4 = 11

r = 11

Find the value of x<br> A. 11.67°<br> B. 42.5°<br> C.18°<br> D.20°
Julli [10]

Answer:

D. 20°

Step-by-step explanation:

The entire angle = 90 degrees you can tell that from the corner indicator

Set the two expressions equal to 90

(3x+10) + (x) = 90

Combine like terms

4x + 10 = 90

Subtract 10 from both sides to cancel it out

4x = 80

Divide each side by 4

x = 20

Check it by substituting x for 20

3(20) + 10 = 70     x = 20     70 + 20 = 90
