hope that helps, God bless!
Answer:
37
Step-by-step explanation:
f(x) = 2x-1
g(x) =x^2 +3
f°g(x) = means put g(x) in for x into the function f(x)
f(g(x)) = 2 (g(x)-1
=2(x^2 +3) -1
Distribute
= 2x^2 +6-1
=2x^2 +5
Now we let x=-4
f(g(-4)) = 2 (-4)^2 +5
=2(16) +5
=32+5
=37
Answer:
4 1/2
Step-by-step explanation:
3÷ 2/3
Copy dot flip
3 * 3/2
Multiply the numerators
3*3 =9
The denominator is 2
Numerator over denominator
9/2
Change to a mixed number
9/2 = 4 1/2
Answer:
10 square2
36 + 64 = 100. In other words, 6² + 8² = 10²
(2,1) and (3,6)
Slope = (6-1)/(3-2) = 5
y = mx + c
y = 5x + c
at point (2,1)
1 = 5(2) + c
1 = 10 + c
c = -9
y = 5x - 9
