Answer:
7
Step-by-step explanation:
if the number is x then you know 2x-9=5
2x=14
x=7
so the number is 7
Answer:
Step-by-step explanation:
<h3>Given GP</h3>
<h3>To find</h3>
<h3>Solution</h3>
<u>Substitute ar in the second equation</u>
- ar⁵= 16
- 4r⁴ = 16
- r⁴ = 4
- r = √2
<u>Then finding a₄</u>
- a₄ = a₂*r² = 4*(√2)² = 4*2= 8
(4 sec) * (-10 ft/sec) = -40 ft.
Answer:

Step-by-step explanation:
we have

Find the inverse of A(x)
Let
y=A(x)

Exchange the variables x for y and y for x

Isolate the variable y


Let

------> function inverse of A(x)
<em>Explanation</em>
For x=1
Find the value of A(x)

The point (1,7) is a solution for A(x)
That means-----> The point (7,1) is a solution for the function inverse g(x)
Verify
For x=7
The point (7,1) is a solution for g(x)
therefore
A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)
Answer:
A.) the number of photos Nina needs to sell to make profit
Step-by-step explanation:
you can tell this because she has to sell X number of photos and times that number by 2 and then take away 14 so her final number to make profit or even make back her money is that X number
