Answer: -4
Step-by-step explanation:
Replace x with 2 in each equation, then subtract g from f:
f(x) = x^2 -4 = 2^2 -4 = 4-4 = 0
g(x) = 1-x = 1-2 = -1
f-g = 0 - -1 = 1
The answer is 1
Answer:
0.8, 0.875, 0.89 or 4/5, 7/8, 0.89
Step-by-step explanation:7/8 is the same as 7 divided by 8 which equals to 0.875.
4/5 is the same as 4 divided by 5 which is 0.8.

Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
<u>Final answers</u>:
- A) y = -3x - 2
- B) y = -3x + 17
