The equations x + 4 = y and 2x + 2 = y form a system that has ...? A. one solution
B. no solution
C. an infinite number if solutions​

A. One solution

Step-by-step explanation:

We are given a system of equations and are asked to find whether it has a certain solution.

y = x + 4

2x + 2 = y

Since both equations end with y, we can substitute them from back to back.

x + 4 = 2x + 2

Subtract 2 from both sides :

x + 2 = 2x

Subtract x from both sides :

x = 2

Solve for y now that you have x by subtituting x with the value.

(2) + 4 = y

2(2) + 2 = y

6 = y

6 = y

Therefore this means that the system of equations is one solution because it intersects at one point (2, 6).

Check the graph.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

a: 1/6, j: 1/4
