Answer:
a, f
Step-by-step explanation:
THat is true
if y = f(x + h) thats a move of h units to the left
Answer:
7.5
Step-by-step explanation:
![56\sqrt{x} = 7.48331477\\](https://tex.z-dn.net/?f=56%5Csqrt%7Bx%7D%20%3D%207.48331477%5C%5C)
So, we rounded up to 7.5, because the decimal digit 8 is higher than 5.
Answer:
1.
The slope is 2
The y-intercept is -10
equation: y = 2x - 10
2.
Slope: 2.5
y-intercept: 1
Equation: y = 2.4x + 1
Step-by-step explanation:
1.
x y
2 12
4 16
8 24
10 28
from 12 to 16 you add 4
from 2 to 4 you add 2
y/x = 4/2 = 2
The slope is 2
The y-intercept is -10
equation: y = 2x - 10
I got the y-intercept because I went from 12 to 0 which is -12, and then 2 - 12 and it's -10

2.
x y
5 4
20 10
30 14
35 16
from 4 to 10, u add 6
from 5 to 20 you add 15
y/x = 15/6 = 2.5
Slope: 2.5
y-intercept: 1
Equation: y = 2.4x + 1
I got the y-intercept because I went from 4 to 0 which is -4, and 5 - 4 is 1.
Hope this helped
So remember that area of a rectangle is a = bh. In this case, our sides are 2 and n - 3 (three less than unknown number) and our area is 22. Using our info, we can form the equation:
. From here we can solve for n.
Firstly, foil 2(n-3): ![22=2n-6](https://tex.z-dn.net/?f=%2022%3D2n-6%20)
Next, add 6 on both sides of the equation: ![28=2n](https://tex.z-dn.net/?f=%2028%3D2n%20)
Next, divide both sides of the equation and your answer will be 14 = n. In context, the value of the unknown number is 14 in.
