There are 12 months in a year so. 85x12=1020
$9.00 per hour. take 45 and divide by 5 you get 9.
Answer:
Average rate of change=-3
Step-by-step explanation:
The average rate of change is given by the relation between the values of f(x) and x, in two different points as follows:
![Change=\frac{f(x_{2})- f(x_{1})}{x_2-x_1}](https://tex.z-dn.net/?f=Change%3D%5Cfrac%7Bf%28x_%7B2%7D%29-%20f%28x_%7B1%7D%29%7D%7Bx_2-x_1%7D)
In this case, ![x_{1}=-2; x_{2}=-1](https://tex.z-dn.net/?f=x_%7B1%7D%3D-2%3B%20x_%7B2%7D%3D-1)
Therefore,
![Change=\frac{((-1)^{2}+10) -((-2)^{2}+10)}{-1-(-2)}=\frac{11-14}{1}=-3](https://tex.z-dn.net/?f=Change%3D%5Cfrac%7B%28%28-1%29%5E%7B2%7D%2B10%29%20-%28%28-2%29%5E%7B2%7D%2B10%29%7D%7B-1-%28-2%29%7D%3D%5Cfrac%7B11-14%7D%7B1%7D%3D-3)
Answer:
Step-by-step explanation:
Remark
The slope intercept line is written as y = mx + b in it's general form.
You can get the slope, m, immediately because it is given as -2
So far what you have is y = -2x + b
y intercept
To get the y intercept, use the point (-3 , 4)
x = - 3
y = 4
4 = -2*(-3) + b
4 = 6 + b Subtract 6 from both sides
4 - 6 = 6-6 + b
b = - 2
Line
y = -2x - 2
(a,8)
y = -2a - 2
8 = -2a - 2 Add 2 to both sides
8 +2 = -2a -2+2 Combine
10 = - 2a Divide by - 2
10/-2 = a
a = -5
(5,b)
y = -2x - 2
x = 5
y = b
b = -2*5 - 2
b = -10 - 2
b = - 12
Answer:
60º
Step-by-step explanation:
A triangle is 180º so you do (180-60)/2 and you get that x=60.
Hope that helps :)
