Assuming that your question is (x-1)(x+2) = [5(x-1)]/x-1
On the right side, the x-1's will cancel out, leaving you with (x-1)(x+2) = 5
expand the left side, giving you x^2 + x -2 = 5
which goes to x^2 +x -7 = 0
the possible values for x are 2.93 and -3.93. I don't think this was your question, so I'll do the other possible question that you might have been asking.
(x-1)(x+2) = 5(x-1)
divide by x-1 on both sides, leaving you with x+2=5
x+2=5
x=5-3
x=3
Answer:
Option 2) Null hypothesis: p = 0.078
, Alternate hypothesis: p > 0.078
Step-by-step explanation:
We are given the following in the question:
According to the National Center of Health Statistics, about 7.8% of all babies born in the U.S. are categorized as low birth weight.
Sample size, n = 1200
p = 7.8% = 0.078
We have to carry a hypothesis test whether national percentage is higher than 7.8% or not.
Thus, we can design the null and the alternate hypothesis
Thus, the correct answer is:
Option 2) Null hypothesis: p = 0.078
, Alternate hypothesis: p > 0.078
Answer:
35
Step-by-step explanation:
if X+Y=5&XY=6 we can guess the numbers easly the numbers are 2&3.
so X^3+Y^3=(2)^3+(3)^3
=2*2*2+3*3*3
=8+27
=35

Answer:
m = 125 is the rate of change or the hourly fee
b value is 500
y = 125x + 500
Step-by-step explanation:
1750 = 500 + m(10)
1250 = 10m
m = 125 is the rate of change or the hourly fee
b value is 500; which is the charge at 0 hours (fixed fee for initial meeting);
use equation y=mx+b
y = 125x + 500
A monomial is an expression with one term. -8c is a monomial.
