Answer:

He has to work 1,000 weeks to make Plan B at least better

Step-by-step explanation:

Step 1: Express the first salary pay

The expression for the first salary is as follows

A=F+(R×T)

where;

A=total first salary

F=fixed income

R=commission rate

T=total sales

In our case;

F=$100

R=15%=15/100=0.15

T=t

replacing;

A=100+(15% of t)

A=100+(0.15×t)

A=100+0.15 t

The equation for the first salary; 0.15 t+100

The expression for the second salary is as follows

In our case;

F=$150

R=10%=10/100=0.1

T=t

replacing;

A=150+(10% of t)

A=150+(0.1×t)

A=150+0.1 t

The equation for the second salary; 0.1 t+150

Equating equation 1 to equation 2 and solving;

0.15 t+100=0.1 t+150

(0.15 t-0.1 t)=150-100

0.05 t=50

t=50/0.05

t=1,000

He has to work 1,000 weeks to make Plan B at least better

Answer:

x = (+ - ) 9

Step-by-step explanation:

x^2 = 81

u know how u can sometimes cancel something out by doing the opposite.

This is one of those times as well. the opposite of ^2 = square root.

so if we take the square root of both sides, this will cancel out the^2 on the left side.

sqrt (x^2) = sqrt(81)

x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.

2. (04.01) Which point could be removed in order to make the relation a function? (4 points) {(-9, -8), (-8, 4), (0, -2), (4, 8)
damaskus [11]

Answer:

We are given order pairs  (–9, –8), (–{(8, 4), (0, –2), (4, 8), (0, 8), (1, 2)}.

We need to remove in order to make the relation a function.

Step-by-step explanation:

Note: A relation is a function only if there is no any duplicate value of x coordinate for different values of y's of the given relation.

In the given order pairs, we can see that (0, –2) and (0, 8) order pairs has same x-coordinate 0.

So, we need to remove any one (0, –2) or (0, 8) to make the relation a function. hope this helps you :) god loves you :)
