PLS HELP MEEEI NEED ANSWERS ASAP ASAP

Brums [2.3K]

Answer:

Associative.

Step-by-step explanation:

In addition and multiplication, it does not matter which two numbers you put together first. On the left aide 6 is associated with 3. On the right side 3 is grouped with 7. It doesn't matter where 3 goes. You still get the same answer.

(6 + 3) + 7 = 6 + (3 + 7)

9 + 7 = 6 + 10

The domain of g(x) = 4x –12 is {2, 3, 6, 8}. What is the range

vlada-n [284]

Answer:

Range - {-4,0,12,20}

Step-by-step explanation:

Given that,

The function is :

g(x) = 4x –12

The domain of the function is {2, 3, 6, 8}.

g(2) = 4(2) –12 = -4

g(3) = 4(3) –12 = 0

g(6) = 4(6) –12 = 12

g(8) = 4(8) –12 = 20

Hence, the range of the function is {-4,0,12,20}.

Hi, I actually have this question not this one sorry

Ivanshal [37]

we know that

If V is the midpoint of SU

then

SV=VU

substitute the given values

2x+18=8x-6

solve for x

8x-2x=18+6

6x=24

Find SV

SV=2x+18

SV=2(4)+18

<h2>SV=26 units</h2>

<h2>VU=26 units</h2>

and

SU=2SV

SU=2(26)

<h2>SU=52 units</h2>

You have two jobs. One job pays nine dollars per hour and the other job pays $7.50 per hour. You worked 18 hours last week and e

sveta [45]

Answer:

$Y =\frac{16.5}{1.5}= 11$

$X = 18-11=7$

And then we conclude that for the first job he works 7 hours and for the second job 11 hours

Step-by-step explanation:

We can define the following notation:

$X$ represent the number of hours worked for one job

$Y$ represent the number of hours worked for the other job

$p_x = 9$ represent the hourly payment for the first job

$p_y = 7.50$ represent the hourly payment for the other job

And we can define the following equations:

$X+ Y= 18$ (1) represent the toal number of hours worked

$9X +7.5 Y = 145.50$ (2) represent the total amount earned

From equation (1) if we solve for X we got:

$X = 18-Y$ (3)

Replacing equation (3) into equation (2) we got:

$9(18-Y) +7.5 Y =145.50$

And after solve the equation we can find the value of Y:

$162 -9Y +7.5 Y =145.50$

$16.5 = 1.5 Y$

$Y =\frac{16.5}{1.5}= 11$

And solving for X from equation (3) we got:

$X = 18-11=7$

And then we conclude that for the first job he works 7 hours and for the second job 11 hours
