Answer:
Supplementary angles add to 180. Let x = the measure of one angle. The other is three and one half times larger, or 3.5x:
x + 3.5x = 180
Step-by-step explanation:
The equation of a line is given by the expression:
y=Mx + b
This is the slope form of an equation where M is the gradient of line and b is the y intercept.
For the slope, M= change in y values/ change is x values
(-3,8) , (-7,8) thus the slope m,=(8-8)/(-7--3)
m=0/-4 =0
the slope is 0
To find the b substitute the values in the equation y=Mx+b
Taking point (-3,8) and slope of 0
y=Mx+b
8=0*(-3) + b
8=0+b
8=b
The value of b is 8
The equation of the line will be;
![y-8=0(x+3)](https://tex.z-dn.net/?f=y-8%3D0%28x%2B3%29)
![y-8=0](https://tex.z-dn.net/?f=y-8%3D0)
![y=8](https://tex.z-dn.net/?f=y%3D8)
The equation of the line is y=8
Answer: 5/10
Step-by-step explanation: When we look at the decimal 0.5, the 5 is in the tenths place and there are 5 of them. Therefore, we can write 0.5 as 5/10.
