Hey there!!
Given :
![f ( x ) = 2x + 7](https://tex.z-dn.net/?f=f%20%28%20x%20%29%20%3D%202x%20%2B%207)
Find f ( 7.5 )
Now, we will need to substitute the value of 7.5 in place of x
![f(7.5) = 2(7.5) + 7](https://tex.z-dn.net/?f=f%287.5%29%20%3D%202%287.5%29%20%2B%207)
![f(7.5) = 15 + 7](https://tex.z-dn.net/?f=f%287.5%29%20%3D%2015%20%2B%207)
![f(7.5) = 22](https://tex.z-dn.net/?f=f%287.5%29%20%3D%2022)
Hope my answer helps!
give some Parameters so that we can solve
Answer:
B: y = -2x + 5
Step-by-step explanation:
-2 - 1 = -3
9 - 3 = 6
= -2
gradient = -2
3 = 1 x -2 + c
3 = -2 + c
5 = c
y intercept = 5
equation = y = -2x + 5
so the answer is option b
To find the <span>percentaje</span> we need to <span>divided</span> the <span>tataol</span> by the amount we end up having.
22.50/19.50=1.15
<span>then</span> we multiply by 100
115%
Then to find the <span>percentaje</span> increase we subtract
115%-100= 15%
So it has an <span>increament</span> of 15%
A polynomial with a degree of 2 can be:
x² + 1
y² + 2
etc..
hope this helps
