Total cost of painting 225 cm² will be:
Cost=(total area)×(cost per cm²)
area=225 cm²
cost per cm²=$0.12
thus the total cost will be:
Cost=0.12×225=$27
Answer: $27
Answer:
see explanation
Step-by-step explanation:
y = ax + b is the equation in slope- intercept form
where a is the slope of the line and b is the y- intercept
To find a use the slope formula
a = (y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (1, - 2)
a =
= -
= - 0.75, hence
y = - 0.75 + b
To find b substitute either of the 2 points into the equation
using (1, - 2), then
- 2 = - 0.75 + b ⇒ b = - 2 + 0.75 = - 1.25 = - 1 
Answer:
y=1/4x+6 1/4

Step-by-step explanation:
Start off with PEMDAS
P-Parentheses
E-Exponents
M- Multiplication
D-Division
A- Addition
S- Subtraction
In order of witch comes first
so 8x3=24
10+24=34
34-2+2=34
