To add or subtract with powers, both the variables and the exponents of the variables must be the same. You perform the required operations on the coefficients, leaving the variable and exponent as they are.
Answer:
Y = 166
Step-by-step explanation:
The missing angle measure in the small trapezoid is 93 degrees. So to solve for “y” you have to make the expression equal to 93.
y - 73 = 93
y = 166

Answer:
see explanation
Step-by-step explanation:
A
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then
A = π × 6² = 3.14 × 36 = 113.04 m²
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 28.26 , then
2πr = 28.26 ( divide both sides by 2π )
r = 
= 
= 4.5 in

Step-by-step explanation:
Answer:
x-intercept is (-4,0) and the y-intercept is (0,-2
Step-by-step explanation:
There are 2 ways to find the y-intercept. One way is to put the equation in slope-intercept form. However, there is a more efficient way as well.
Another way to do it is to plug 0 in for x and y. The x-intercept will have the coordinate of (x,0). So to find the x-intercept you can plug in 0 for y and solve for x. To find the y-intercept do the opposite and plug 0 in for x.
So, first, plug 0 in for y
- x+2(0)=-4
- x+0=-4
- x=-4
Then plug in 0 for x
- 0+2y=-4
- 2y=-4
- y=-2
Therefore, the x-intercept is (-4,0) and the y-intercept is (0,-2).
