Answer:
25
Step-by-step explanation:
So first we'll input the numbers then since we have them.
5(1) + 3(7) - 1^3
So we're going to use the order of operations here first (PEMDAS) and start with the exponent because the parenthesis I used just represent multiplication. And 1 to the power of anything is still 1. Even 1^1000000000000000000000000000.....
It's still 1.
So now we have this:
5(1) + 3(7) - 1
Now we can multiply:
5 + 21 - 1
Then, add and subtract:
26 - 1
To get:
25
Answer:
![y = x](https://tex.z-dn.net/?f=y%20%3D%20x)
Step-by-step explanation:
The given equation is
![y = x + 5](https://tex.z-dn.net/?f=y%20%3D%20x%20%2B%205)
The slope of this line
![m = 1](https://tex.z-dn.net/?f=m%20%3D%201)
Since all parallel lines have the same slope, the slope of our line is also m=1.
We now use the point-slope formula
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Since the line passes through (-1,-1)
We gave
![x_1=-1,y_1=-1](https://tex.z-dn.net/?f=x_1%3D-1%2Cy_1%3D-1)
We substitute the slope and point to get
![y - - 1 = 1(x - - 1)](https://tex.z-dn.net/?f=y%20-%20%20-%201%20%3D%201%28x%20-%20%20-%201%29)
![y + 1 = x + 1](https://tex.z-dn.net/?f=y%20%2B%201%20%3D%20x%20%2B%201)
![y = x](https://tex.z-dn.net/?f=y%20%3D%20x)

Answer:
The mean height is <u>69 inches</u><u><em>.</em></u>
Step-by-step explanation:
The mean or Average is a measure of the center data i.e Sum of all the observation and dividing by the total number of observation.
Here, sum of observation is equal to the sum of the heights of the players in the basketball team.
Total number of observation =10
Sum of observation=70+68+72+66+68+69+66+71+74+66=690 inches.
![MeanHeight=\frac{Sum of observation}{Total number of observation}](https://tex.z-dn.net/?f=MeanHeight%3D%5Cfrac%7BSum%20of%20observation%7D%7BTotal%20number%20of%20observation%7D)
![Mean Height=](https://tex.z-dn.net/?f=Mean%20Height%3D)
![\frac{690}{10}=69 inches](https://tex.z-dn.net/?f=%5Cfrac%7B690%7D%7B10%7D%3D69%20inches)
Therefore,the Mean Height is, 69 inches
Answer:
D
Explanation Given:
if you plug in 1 for x then y=(3)^2
(3)^2=9
you have your two coordinates. (1,9)
