Answer:
<h2>(g o f)(- 4) = 570</h2>
Step-by-step explanation:
f(x)=4x+5
g(x)=4x² - 5x - 3
To find (g o f)(-4) we must first find
(g o f )(x)
To find (g of f)(x) substitute f(x) into g(x)
That's
(g o f)(x) = 4(4x + 5)² - 5(4x - 5) - 3
= 4( 16x² + 40x + 25) - 20x + 25 - 3
= 64x² + 160x + 100 - 20x + 22
(g o f)(x) = 64x² + 140x + 122
To find (g o f)(- 4) substitute the value of x that's - 4 into (g o f)(x)
Thats
(g o f)(- 4) = 64(-4)² + 140(-4) + 122
= 64(16) - 576 + 122
= 1024 - 454
We have the final answer as
<h3>(g o f)(- 4) = 570</h3>
Hope this helps you
Answer:
So actually #1 is answer. Thats because if we see last one it doesn't have a right angle but the original does. In the next one the angles dont match. The 23 and 67 degree angles are not in the original figure. We can see that the last one has those angles and the sides are switched and just multiplied by 2. Therefore the answer to this question is:
<h2><u>
#1 is the answer</u></h2>
Answer:
Hi there!
Your answer is:
17= 2A-5
Alonzo is 11
Step-by-step explanation:
Frank=2A -5
Frank = 17
17= 2A-5
A = Alonzo's age
Alonzo's age is:
17= 2A-5
+5
22 = 2A
/2
11= A
Answer:
(6-2x)(3-2x)x=40
Step-by-step explanation:
(-2x-2x) (6+3)x=40
8x=40
8x/8=40/8
x=5
