<span>If you are spreading fertilizer on a golf course at the rate of 40 pounds per 10,000 square feet and the course is 320 acres, you can calculate the amount of fertilizer that will be needed by converting acres to square feet. So, 320 acres are 13,939,200 square feet which means you will need 55,756.8 pounds of fertilizer. </span>
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

Answer:
domain = {0, 1, 2, 3}
range = {0, -1, -2, -3}
Step-by-step explanation:
The function is the set of ordered pairs (0, 0), (1, -1), (2, -2). (3, -3)
The domain is the set of x values. So, domain = {0, 1, 2, 3}
The range is the set of y values. So, range = {0, -1, -2, -3}
