the number is 8 because the equation is (x * 3) + 4 so replace x with (8) and its (8 * 3) + 4 = 28 :)
Answer: Use the given functions to set up and simplify (f - g)(x). You should get 3x^2 +4x+2
If the resultant line is a straight line,it represents a
direct variation.
Answer:
$4.80
Step-by-step explanation:
By adding the prices together, you can determine that the 5 pounds of the trail mix cost $24.
Simply divide 24 by 5 to get the price per pound, and you will get 4.8
Answer: 4
Since we need to find the y, we're going to substitute the x's with the numbers in the x column.
Let's try to find the first y box.
We're going to substitute all of the x's with -0.5.
y = 4(-0.5)^2 - 8(-0.5) + 4
Now, we're just going to solve that.
-2^2 - 4 + 4
-2 squared is 4. It's a positive 4 because a negative times a negative is a positive.
4 - 4 + 4
= 4
