for 20 battery..it would cost 30
Step-by-step explanation:
Answer:
46=6+8x
5 friends
Step-by-step explanation:
subtract 6 from 46 to get 40.
divide 40 and 8x by eight to get 5.
The value of the composite function is 20
<h3>Composite function</h3>
Composite function is also known as function of a function
Given the following expression as shown below;
f(x)= 2x^2 -4x +9
g(x)= 4x +1
Determine (fog)(x)
f(g(x) = f(4x+1)
f(4x+1) = 2(4x+1)^2-4(4x+1)+9
f(4x+1) = 2(16x^2+8x+1)-16x-4+9
f(4x+1) =13x^2+16x+2-16x+5
f(4x+1) = 13x^2 + 7
If the value of x is -1, hence;
f(4x+1) = 13(-1)^2 + 7
f(4x+1) = 20
Hence the value of the composite function is 20

Answer:
<h2>y = a(x + 3)² - 2 where <em>a</em> is any real number except 0.</h2>
Step-by-step explanation:
The vertex form of a parabola:

(h, k) - vertex
We have the vertex at (-3, -2) → h = -3 and k = -2.
Substitute:

Answer:
4080 hits.
Step-by-step explanation:
By proportion that would be 1700 * 24/10
= 4080.
