Answer:
(x−1)(2x3+2x2+2x−1)
combine like terms, then factor
Answer:
see the table below
Step-by-step explanation:
s b
1 18
3 23
5 27
7 31
Remember you can do anything to an eqution as long as you do it to both sides
easy
first one
flat rate+variable rate=amount paid
flat rate=35
variable=15 times hours, so if h=hours then
and amount paied is 95
35+15h=95 is da equation
if we solve
mins 35 both sides and divide both sides by 15
h=4
2nd one
add 5 to both sides and times 4 both sides
c/4=9
c=36
3rd photo
add 6 to both sides
y+6-6≥12+6
y+0≥18
y≥18
Answer:
t = 0.05 / 0.017
Step-by-step explanation:
Given the table :
Variable ____ Estimate
Intercept 1 ____ 15.5 ____2.96
Temp 1 _______0.05 ___ 0.017
R-sq = 0.73
The test statistic for a regression test :
t = b1 / E
Where ;
b1 = slope ; E = Standard error of the slope
From the result table ;
b1 = 0.05 ;
E = 0.017
The test statistic, t = 0.05 / 0.017
Answer:
18.2%
Step-by-step explanation:
For decimals, just move the point two times to the right.
