Answer:
Step-by-step explanation:
C. -11<x<-4
|-2x-15|<7 split into possible cases
- 2x - 15 < 7, - 2 x - 15 > 0
-(- 2x - 15 ) <7, -2x - 15 < 0 solve the inequalities
x>-11, x < -15/2
x< -4, x> -15/2 Find the intersections
[ -11, -15/2 ]
-15/2, -4] Find the union
[-11, -4 ] Simplify
-11<x<-4
5% = 0.05
50 x 0.05 = $2.50
Total tax will be $2.50
Total amount he will pay = 50 + 2.50 = $52.50
Answer:
W = 4inches
Length is 2 inches longer then the width
Step-by-step explanation:
6x4=24inches
Y=mx+b helps to find slope of a line.
B is where it starts on the y axis.
m is the slope.
x^2*(-3x)=-3x^3. The power of x becomes 3 because you add the powers of x. (2+1=3)
