<span>f(-10)=12, x = -10, y = 12
f(16)=-1, x = 16, y = -1.
so, we have two points, let's check with that,

It should be the multiplication first remember PEMDAS. Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction. So Letter D is the answer.
Answer:
Option D. Divide the number of acres by the number of horses
Step-by-step explanation:
Let
x-----> the number of acres for each horse
we know that
------> inequality A
To find the number of acres for each horse, divide the number of acres by the number of horses
so
substitute the value of x in the inequality A
------> is true
therefore
The farmer has enough acreage for 12 horses
Ok so if you notice every choice is solved for a, all you have to do is isolate "a" in 7a-8b=10x. Start by moving 8b to the other side and to change the sign. Now it is 7a = 10x + 8b. Then divide everything by 7 and you get a = (10x + 8b)/7
