Answer:

Step-by-step explanation:

g^{-1} (-3)=7\\

let h(x)=y

y=2x-3

flip x and y

x=2y-3

2y=x+3

y=\frac{1}{2}(x+3)\\or~h^{-1}(x)=\frac{1}{2}(x+3)\\(h^{-1} oh)(x)=h^{-1}(h(x))=h^{-1}(2x-3)=\frac{1}{2}(2x-3+3)=\frac{1}{2}(2x)=x\\(h^{-1}oh)(1)=1

A factory sells backpacks for $40.00 each. The cost to make 1 backpack is $10.00. In addition to the cost of making backpacks, t
Angelina_Jolie [31]

Answer:

<h2>The factory needs to sell 327 packbacks to make at least 9,800 per week.</h2>

Step-by-step explanation:

We know that each backpacks is sold for $40.00.

The goal is to make at least $9,800 per week. With this information we can define the inequality

40x -10x \leq 9,800

Where x represents backpacks. Notice that this inequality is about profits, that's why we subtract the cost from the sell price, in this case, the profid margin is $30.00 per backpack, so

30x\leq 9,800

Solving for x

x\leq \frac{9800}{30}\\ x \leq 326.67

Therefore, the factory needs to sell 327 packbacks to make at least 9,800 per week.

What is the length of AB?
Tresset [83]

Answer:

angle B'CA'= angle BCA..... (common angle)

angle B'A'C = angle BAC.....(corresponding angels)

therefore,

ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)

therefore,

B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)

now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9

5 / BA. = 6 / 9

therefore, 5 / BA. = 2 / 3

ba \:  =  \frac{5 \times 3}{2 }  \\  =  \frac{15}{2}  \\  = 7.5

Answer : AB = 7.5 units
