Find the x- and y- intercepts of the line. 2X+3y=-18
Anna71 [15]
To find the x-intercept, plug zero into y and solve for x.

2x+3(0)=-18

2x=-18
/2     /2

x=-9
To solve for the y-intercept, do the same thing, but instead plug zero into the x-intercept to solve for y.

2(0)+3y=-18
3y=-18
/3     /3

y=-6

So, your answer to your question is the y-intercept=-6, and the x-intercept=-9
Hope this helps!:)

Melissa is 9 years old. How old will she be in x years?
solniwko [45]

Answer:

Taking that you didn't provide any other information about the values of x..

The only plausible answer, which probably isn't your case but still can be valid out of context is 19.

Step-by-step explanation:

"X" is 10 in Roman numbers.

9 + 10 = 19

(But I suppose that you had more details to the question that you didn't yet share :) )

OR.. the answer might be an algebraic expression..

<u><em>"9+x" years old.</em></u>

Gnom [1K]

Answer:

They donated 6%.

Step-by-step explanation:

The total sales were $9800.

The amount donated is $588.

We want to know what percent of 9800 is 588.

Let's make an equation.

what percent of 9800 is 588

x/100 • 9800 = 588

Divide by 9800.

x/100 = 0.06

Multiply by 100.

x = 6

They donated 6%.

Hope this helps!
