15) x^2-2x-8=1/4x-1
x^2-2.25x-7=0
4x^2-9x-28=0
(x-4)(4x+7)=0
x-4= 0 or 4x+7=0
x=4 or x= -7/4=-1.75
16) answer hides in the f(x) equation
the trick is to think of the value that will make the (x-4) =0 and and the y value can be directly plugged off from the +c
therefore, ans is x=2 y= 4
(2,4)
Answer:
1 inch
Step-by-step explanation:
The formula for the volume of a cylinder:
V = πr²h, where r=radius and h = height
Using 7.1 for 'V' and 1.5 for 'r' (1/2 of the diameter), we can fill in the values and solve for 'h':
7.1 = π(1.5)²h or 7.1 = 7.065h
h = 1 inch
Question: If <u>x-25 = 11</u>, then what is the solution of x/6?
Step-by-Step Explanation:
1. 25 + 11 = 36
2. x = 36
3. 35/6 = 6
40,000 + 0.07(120,000) =
40,000 + 8,400 =
