Which method is used in elimination to find the solutions of x + 3y = 9 and x - 3y = 8?

weqwewe [10]

Answer:

x=17/2 y=1/6

Step-by-step explanation:

-1(x+3y=9)

1(x-3y=8)

_________

-x-3y=-9

x-3y=8

________

-6y/6=-1/6 y=1/6

x+3(1/6)=9

x+ 1/2=9

- 1/2 - 1/2

x=17/2

Can someone solve this for me with their explanation please?

First you want to subtract 36

so it looks like this $\sqrt[4] {(4x+164)^3}=64$

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

${(4x+164)^3}=64^4$ which is equal to ${(4x+164)^3}=16777216$

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23

Terrell loves to listen to music, so he buys a subscription to a music-streaming service. He pays $4.99 each month. How much doe

Ilya [14]

Answer:

$Yearly = \$59.88$

Step-by-step explanation:

Given

$Monthly = \$4.99$

Required

Determine the yearly cost

To do this, we multiply the monthly subscription by 12

$Yearly = Monthly * 12$

$Yearly = \$4.99 * 12$

$Yearly = \$59.88$

<em>Hence, the yearly servics cost is $59.88</em>
