Answer:

u= -3  v=11

Step-by-step explanation:

7u+2v=1     17u+6v=-9

-3(7u+2v=1)= -21u-6v=-3

-21u-6v=-3  +  17u+6v=-9 = -4u= -12

u=-3

7(-3)+2v=1

-21+2v=1

2v=22

v=11

Omari buys a computer for $1,083. She
Yuliya22 [10]

Answer:

6 months.

Step-by-step explanation:

To find the answer, we first need to find out how much Omari paid for the down payment. To find this, you multiply 1083*0.20 and you get $216.60. So we subtract the down payment from the total leaving us with $866.40. Now to find out how many months it would take Omari to pay, we divide 866.40/144.40 since each month she pays $144.40 a month. Once you divide 866.40/144.40, you are left with an answer of 6 months.

Describe the steps in solving the linear equation 3(3x − 8) = 4x + 6.
Fittoniya [83]

Answer:

x=6

Step-by-step explanation:

3(3x-8)=4x+6

First you would distribute the 3 on the L side to the parenthasies

9x-24=4x+6

Then, you would subtract 4x from both sides because it is the smallest X value

5x-24=6

Add 24 to both sides (inverse operations)

5x=30

divide both sides by 5

x=6

lianna [129]

Answer:

  see below

Step-by-step explanation:

A graphing calculator can help you do this.

__

The function crosses the y-axis where x=0.

  g(0) = -5^0 +5 = -1 +5

  g(0) = 4

The function crosses the x-axis where g(x) = 0

  0 = -5^x +5

  5^x = 5 = 5^1

  x = 1

  g(1) = 0

The points of interest are (0, 4) and (1, 0).
