Hello from MrBillDoesMath!
Answer:
x = 0, +\-3
Discussion:
x^3 = 9x => subtract 9x from both sides
x^3 - 9x = 0 => factor x from both terms
x(x^2-9) = 0 => x = 0 or x^2 - 9 = 0
x = 0, +\-3
Thank you,
MrB
Answer: -9/1
Step-by-step explanation: you want to get x and y on opposite sides so you subtract 9x and that gives you y=-9x+9 because the nine on the right side doesn’t have a negative in front of it so you know it’s positive. Your slope is whatever comes before the x so since it’s -9 that means it’s -9/1
Answer:
53
Step-by-step explanation:
4ft x 12 = 48 in
48 in+ 5 in= 53
Answer:
The length is 2.5 units
Step-by-step explanation:
Before we find the value of the length of the side, we need the measure of the coordinates after dilation
B’ = 1/2 B = 1/2(3,2) = (1.5, 1)
C’ = 1/2 C = 1/2( 0,-2) = (0,-1)
The measure of the length is the distance between the two points
Mathematically, that would be;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(0-1.5)^2 + (-1-1)^2
D = √(2.25 + 4)
D = √6.25
D = 2.5 units
