The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
Answer:
![m=0](https://tex.z-dn.net/?f=m%3D0)
Step-by-step explanation:
Given
See attachment
Required
Determine the slope of the line
From the attachment, we have the following points
![(x_1,y_1) = (-4,1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%28-4%2C1%29)
and
![(x_2,y_2) = (3,1)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%283%2C1%29)
The slope m is then calculated using:
![m = \frac{y_2- y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Substitute values for the x's and y's
![m = \frac{1-1}{3 - (-4)}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1-1%7D%7B3%20-%20%28-4%29%7D)
![m = \frac{1-1}{3 +4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1-1%7D%7B3%20%2B4%7D)
![m = \frac{0}{7}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B0%7D%7B7%7D)
![m=0](https://tex.z-dn.net/?f=m%3D0)
<em>Hence, the slope is 0</em>
Answer:
Third
Step-by-step explanation:
First would be, simplified, 2x+10=2x-10
Second, simplified, -2x-10=2x-10
Third, simplified, -2x-10=-2x-10
Fourth, simplified, -2x+10=2x-10
So it's third :)
hope this helps :D
Answer:
1 1/2
Step-by-step explanation:
one and a half because you have a half leftover and 1 whole
Answer:
<em>3.27*10^22</em>
Step-by-step explanation:
Given the expression 9.6x10^85/3x10^63, we are to write it on scientific notation as shown:
9.6x10^85/3x10^63
= (9.8/3) * (10^85/10^63)
= (9.8/3) * 10^{85-63}
= (9.8/3) *10^22
= 3.27 *10^22
<em>Hence the expression in scientific notation is 3.27*10^22</em>
