Answer:
y=3x+10
Step-by-step explanation:
First, put the equation into point-slope form.
y-y1=m(x-x1)
y-4=3(x+2)
Next, distribute 3 to (x+2) and simplify.
y-4=3x+6
y=3x+10
What is 7x5x4, it is 140 so the volume is 140in^3 its a pretty simple problem
Design = $45

number of children, x
total cost, f(x) = $5.5x + $45
Answer:
x = 1 y= 3
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite.
Simplify.
Add the two equations together to eliminate y from the system.
Divide each term by 8 and simplify.
Substitute the value found for x into one of the original equations, then solve for y.
The result can be shown in multiple forms.
Point Form:
(1,3)
Equation Form:
x=1 ,y=3
