73, 75, 77, because those numbers are only dividable by 1.
Hi there! :)
y = 2x + 2
y = -2x - 6
Both equations are equal to "y", so we can simply set both equations equal to each other:
2x + 2 = -2x - 6
Add "2x" to both sides:
2x + 2x + 2 = -6
Subtract "2" from both sides:
4x = -8
Divide both sides by 4:
4x/4 = -8/4
x = -2
Substitute in this value of "x" back into either of the equations:
y = -2(-2) - 6
y = 4 - 6
y = -2
Therefore, the solution of the equations is at (-2, -2).

You can't really determine the amount of computers from this question, they're obviously not going to have one computer for everyone so half third, or even a fourth of the school population
Answer:
a = 15
Step-by-step explanation:
The graph of function g(x) is described by g(x)=ax−7, or y = ax−7.
y = g(x)=ax−7 passes through (1/3, -2). We can subst. -2 for y and 1/3 for x to determine the value of the coefficient a:
-2 = g(1/3) = a(1/3) - 7
Solve for a. First, add 7 to both sides: 5 = a(1/3).
Next, multiply both sides by 3: 15 = a, or a = 15.
