If you have
|a|=b, then solve for the variable in euations
a=b and a=-b
for ineqalities, it is much trickier
for
|a|>b, assume a>b and a<-b
for
|a|<b, asssume -b<a<b
Answer: There are no choices so unfortunately I can't give you an answer
Step -by-step explanation:
Answer:
Step-by-step explanation:
Your question has typographical errors. The equation is 2a + b = 15.7, not 2e+b-15.7
2a + b = 15.7
b = 15.7 - 2a
since a > b, a = 6.3 cm
b = 15.7 - 2·6.3 = 3.1 cm
F(x)=3x+18
That is the awnser they I got
10 <0.25 (x + 1) <11
We must solve two inequalities in this case.
Inequality 1:
10 <0.25 (x + 1)
10 / 0.25 <x + 1
40 <x + 1
40-1 <x
39 <x
Inequality 2:
0.25 (x + 1) <11
(x + 1) <11 / 0.25
(x + 1) <44
x <44-1
x <43
The final result is:
39 <x <43
Answer:
39 <x <43
