Step-by-step explanation:
Answer:
y is 90
Step-by-step explanation:
The y/x is proportional per point (x,y) since this is a direct variation.
That is ,
.
Cross multiply:

Simplify:

Divide both sides by -3


Imagine each horizontal line as 180 degrees. So if your angle measure on the top right is 81 the other side of that will be 99 degrees and then you can apply vertical angles. Since angle two is a vertical angle to the degree measure of 81 it is also 81. Which means angle three is equal to angle 1, which is 99 degrees. Now since the horizontal lines are parallel the same angle measure will apply to angles 4,5,6, and 7
Final answer angles 1,3,4,7 are 99 degrees
And angles 2,5,6 are 81 degrees
Answer: ≅37.68
Step-by-step explanation: The formula for circumference is πd. pi is equal to 3.14, so 3.14 x 12 is ≅37.68
Answer:
Option A is correct.
Step-by-step explanation:
Given
To determine
What is the equation in the standard form of the line that passes through the point (4, −8) and has a slope of 1/4.
Using the point-slope form of the line equation

where
- m is the slope of the line
substituting the values m = 1/4 and the point (4, -8)



Subtract 8 from both sides



Writing the equation in the standard form
As we know that the equation in the standard form is
Ax+By=C
where x and y are variables and A, B and C are constants
so



Therefore, the equation in the standard form of the line that passes through the point (4, −8) and has a slope of 1/4 will be:

Hence, option A is correct.
