Answer:
Step-by-step explanation:
<u>Increase by 23%</u>
- x + 23% of x =
- x + (23/100)x =
- x + 0.23x =
- (1 + 0.23)x =
- 1.23x
1.23 is the answer

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Step-by-step explanation:
We can find the slope through two points.
m = (y2 - y1)/(x2 - x1)
m = (4 - -5)/(4 - -8)
m = 9/12 = 3/4
The slope of the line is 3/4.
Slope-intercept form of a line is y=mx+b. Where m is the slope and b is the y-intercept.
y = 3/4x + b
A point on the line is (4, 4). x = 4 and y =4.
4 = 3/4(4) + b
4 = 3 + b
b = 1
The y-intercept is 1.

A= 3631.68
Step-by-step explanation:
the formula to find the surface area is A=2πrh+2πr^2 so when you substitute all your radius values and height values, you get approximately 3631.68
Answer:
y=1
x=-2
Step-by-step explanation:
You're given one, so solve for y by entering -2 (x) into it's equation.
y=x+3
y=-2+3
y=-1
The other is given, so you have your answer.
