Answer:
This area is represented by the function m (x), where x is the length of the radius of the circle in feet. The homeowner estimates that he will pay $1.50 per square foot of mulch. This cost is represented by the function g (m), where m is the area requiring mulch.

Step-by-step explanation:
the box plot is divided into quarters, the line on the end to 20 being 1/4th, the start of the box to the line in the box being another 1/4th, the middle line to the end of the box is another 1/4th, and the last line is the last 1/4th

Answer:
- to eliminate x: multiply the first by 3, and the second by -4
- to eliminate y: multiply the first by 2, and the second by 5
Step-by-step explanation:
Pick the variable you want to eliminate. Determine the coefficients of that variable in the two equations. Negate one of them. Multiply each equation by the coefficient that came from the other equation.
__
<u>To eliminate x</u>
The x-coefficients are 4 and 3. If we negate 4, then the resulting y-coefficient will be positive. We choose to multiply the first equation by 3, the second by -4.
Here is the result of adding those:
3(4x +5y) -4(3x -2y) = 3(7) -4(-12) ⇒ 23y = 69
<u>To eliminate y</u>
The y-coefficients are 5 and -2. If we negate -2, then the resulting x-coefficient will be positive. We choose to multiply the first equation by 2 and the second by 5.
Here is the result of adding those:
2(4x +5y) +5(3x -2y) = 2(7) +5(-12) ⇒ 23x = -46
Answer:
The radian measure of the angle drawn in standard position that corresponds with the ray containing the coordinate point 
is approximately 
radians.
Step-by-step explanation:
With respect to origin, the coordinate point belongs to the third quadrant, which comprises the family of angles from 
to 
. The angle in standard position can be estimated by using the following equivalence:
The radian measure of the angle drawn in standard position that corresponds with the ray containing the coordinate point is approximately radians.
(-10= xy + z ) (-z)
(-10-z = xy ) (1/y)
-10/y - z/y = x
x = -(10+z)/y
