Given:$75
25 hours
Painting USA : Fixed cost: $75 ; Variable Cost: $25x
Total Cost = 75 + 25(25) = 75 + 625 = 700
Upscale Home Painting: No Fixed Cost ; Variable Cost : $40x
Total Cost = 40(25) = 1,000
The most cost effective company will be Painting USA whose charge will amount to $700.
Answer:

Step-by-step explanation:
Quadratic Formula: 
√-1 is imaginary number i
Step 1: Define
y = -3x² + 4.5x - 20
a = -3
b = 4.5
c = -20
Step 2: Substitute and Evaluate







Answer:
DB = 13 cm
Step-by-step explanation:
ΔCAB ≅ ΔDBA by ASA, so CA ≅ DB by CPCTC.
CA = 13 cm, so DB = 13 cm.
Answer:
Equation of line in slope-intercept form is: y = -8x-39
Step-by-step explanation:
Given points are:
(-4, -7) and (-6, 9)
The slope-intercept form is given by the equation

Here m is the slope of the line and b is the y-intercept.
m is found using the formula

Here
(x1,y1) = (-4-7)
(x2,y2) = (-6,9)
Putting the values in the formula

Putting slope in general equation

Putting (-6,9) in the equation

Putting the value of b we get

Hence,
Equation of line in slope-intercept form is: y = -8x-39
