Answer:
A
Step-by-step explanation:
It is A, because it tells you the equation of
-5x + 8 ≥ -7
Because the key on the right tells you that shaded squares are negative and white ones are positive.
You can then subtract both sides by 8 to isolate the -5x and the equation becomes:
-5x ≥ -7 - 8
Which simplifies to
-5x ≥ -15
which you can now divide both sides by -5 to get
x ≥ 3
BUT WAIT
the general rule is that when you divide a variable (in this case x) by a negative number, you have to flip the inequality sign
so ≥
should become ≤
so the equation is x ≤ 3
To make this easy you should put the equation into slope-intercept form :
y = mx + b
the y-intercept is b
remember : the y-intercept can be 0

2/9g= -8
g = -8 ÷ 2/9
g = -36
The greatest whole number that rounds to 2,500 is 2,549. The least whole number that rounds to 2,500 is 2,450.
G(30) = 2/3(30)
g(30) = 20
The answer is 20
