<h3>Answer:</h3><h3>Multiply the first equation by 3</h3>

<h3>explanation</h3>

To solve a simultaneous equation using elimination method, you eliminate one variable first.

Before you can do that, the coefficient of one of the variable in the two equations must be same.

From the questions, for the coefficient of one variable in the two equations to be thesame, we multiply the first equation by 3.

If we do this, the coefficient of Y in the two equations will now be 3.

So that the correct option is

<h2>Multiply the first equation by 3</h2>

ALGEBRA 2!!!!!!!HELP
Inessa [10]

Answer:

x = - 1, x = - 11

Step-by-step explanation:

Given

2| x + 6 | - 4 = 6 ( add 4 to both sides )

2|x + 6 | = 10 ( divide both sides by 2 )

| x + 6 | = 5

The absolute value function always gives a positive result, but the expression inside can be positive or negative, that is

x + 6 = 5 or - (x + 6) = 5

solve both

x + 6 = 5 ( subtract 6 from both sides )

x = - 1

or

- (x + 6) = 5 , that is

- x - 6 = 5 ( add 6 to both sides )

- x = 11 ( multiply both sides by - 1 )

x = - 11

Select the correct answer.
Leviafan [203]

Answer:

The graph of function g is the graph of function f shifted 6 units up.

Step-by-step explanation:

Given

f(x) = 2^x

g(x) =2^x + 6

Required

Compare g(x) to f(x)

Substitute f(x) = 2^x in g(x) =2^x + 6

g(x) = f(x) + 6

<em>This implies that f(x) is shifted 6 units upward to give g(x)</em>

Through: (-1, 0), parallel to y = 3x
evablogger [386]

y = mx + b

m = slope

b = y-intercept

Since it is parallel to the equation y = 3x it means that the equation that goes through point (-1, 0) has the same slope (3x)

To find the b plug the x and y of point (-1, 0) into the equation: y = 3x + b then solve for b

0 = 3(-1) + b

0 = -3 + b

0 + 3 = (-3 + 3) + b

3 = b

so...

y = 3x + b

Hope this helped and made sense!
