-2[2.2x-3.3]=-6.6
[2.2x-3.3]=-6.6 /-2
[2.2x-3.3]=3.3
We have two equations:
1)
2.2x-3.3=3.3
2.2x=3.3+3.3
2.2x=6.6
x=6.6/2.2
x=3

2)
2.2x-3.3=-3.3
2.2x=-3.3+3.3
2.2x=0
x=0/2.2
x=0

Answer: we have two solutions: x=0 and x=3.

-2|2.2x - 3.3| = -6.6. From it: |2.2x - 3.3| = 3.3. We have 2 variants: 1) 2.2x - 3.3 = -3.3. Then 2.2x = -3.3 + 3.3, so 2.2x = 0 => x = 0. 2) 2.2x - 3.3 = 3.3. Then 2.2x = 3.3 + 3.3, so 2.2x = 6.6 => x = 3. Answer: 0; 3.

I need help with number 8

murzikaleks [220]

Since we know what he earns hourly, and his sales, we can figure out his full gross pay for the week.
As so:

We can set up an equation like this:
h = hours
s = sales
9.60h + 5%s

Now, we substitute.
9.60(35) + 5%(230)

Next, solve.
336.00 + 11.50
$347.50

$347.50 was Glen's gross pay for the week.

Hope I could help! If my math is wrong, or I did not provide the answer you were looking for, let me know! However, if I did well, please consider marking as Brainliest!
Have a good one!

F (x) = 7 (x-1) +8 what is the value of f (1)

STALIN [3.7K]

Answer:

Step-by-step explanation:

f (x) = 7 (x-1) +8

For f(1) we plug 1 into x.

f(1) = 7 (1-1) +8

Simplify

f(1) = 8

The Gaineys and the Arnolds are saving money for a trip to Utah to go snowboarding. The Arnolds are going to save a nickel on th

Debora [2.8K]

Write a recursive and explicit formula for each option.

The Arnolds

Save a nickel on the first day of the month and then double the amount each day for a month

=> a1 =0.05

=> a2 = a1* 2 = 0.05*2

=> a3 = a2*2 = a1* 2*2

..............................................

=>recursive an = $a_{n-1} *2$

=> explicit an = 0.05* $2^{n-1}$

The Gaineys

Start their savings by saving $10 on the first day and then $10 each day of the month

=> a1 = 10

=> a2 = a1 + 10 = 20

=> a3 = a2 +10 = 20 +10 =30

........................................................

=> recursive an = $a_{n-1} +10$

=> explicit an = 10 + 10( n-1)

Hope it will find you well.

QUESTION 2. the feasible region shows the number of chairs x and tables y that a furniture company can build each week.

GalinKa [24]

Answer:

Part a) The company can not build 12 chairs and 5 tables

Part b) The company can build 18 chairs and 3 tables

Part c) The company can build 12,13,14,15,16 or 17 chairs

Step-by-step explanation:

we know that

If a ordered pair is a solution, then the ordered pair must be belong to the feasible region of the graph

Part a) Can the company build 12 chairs and 5 tables?

In this problem we have the ordered pair A(12,5)

Plot and verify if the point belong to the feasible region of the graph

see the attached figure to better understand the problem

The point A is not on the feasible region

therefore

The company can not build 12 chairs and 5 tables

Part b) Can the company build 18 chairs and 3 tables?

In this problem we have the ordered pair B(18,3)

Plot and verify if the point belong to the feasible region of the graph

see the attached figure to better understand the problem

The point B is on the feasible region

therefore

The company can build 18 chairs and 3 tables

Part c) One week, the company decides to build 4 tables. how many chairs can the company build?

For y=4

Find the value of x in the graph

The solutions point for y=4 tables are

(12,4), (13,4),(14,4),(15,4),(16,4) and (17,4)

therefore

The company can build 12,13,14,15,16 or 17 chairs
