Answer: 1. x= -12 2. x= 12
Step-by-step explanation:
1. 5(+3)=−45
5x+15−15=−45−15
5x= -60
5x/5 = -60/5
x = -60/5
x= -12
2. 1x/2−4=2
x/2 -4=22−4+4=2+4
/2=6
2⋅2=2⋅6
x=2⋅6
x= 12

Answer:</h2>
First: info on point-slope form.
- Formula: <em>y - y₁ = m(x - x₁)</em>
We need to find the slope of the line first.
Slope: 
Now we can complete the point-slope equation of the line.
*These equations are equivalent.
8 is right but 7 is wrong. The correct answer for 7 is 15÷(1+2)=5
Find the center of the door.
70.33/2=35.165cm
Find the center of the towel rack
24.25/2= 12.125cm
The towel rack will be 12.125cm from the center of the door in either direction. To get the location of either end add 12.125cm or subtract 12.125cm from 35.165cm.
Note: I used decimals, this can also be done with fractions.
Answer:
Step-by-step explanation:
I think you're asking how we use formulas to find areas and volumes.
There's no one area formula; the formula we use to calculate an area depends upon the shape.
For example, the area of a square of side length s is A = s^2.
The area of a triangle with base b and height h is (1/2)*b*h.
Similarly, the choice of formula for the purpose of calculating voume depends upon the shape of the 3-dimensional object.
For example, the volume of a cube with side length s is V = s^3.
The volume of a cylinder with radius r and height h is V = (1/3)πr^2*h.
