Answer:
40
Step-by-step explanation:
As the total circumference of a circle is 360 degrees, the measure of the unknown arc is 360-150-130=80 degrees.
So, by the inscribed angle theorem, angle 1 measures 40 degrees.
The graphs have the same slope (2) and are parallel
The difference is the y intercept
y = 2x has as y intercept of 0
where y = 2x-7 has a y intercept of -7
There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.
We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34
Now, we need to divide -34 by 2:
-34/2 = -17
The answer is: -17
