-2x-4y = 2
-2x-4y+4y = 2+4y
-2x=4y+2

Divided by 2:
-2x/-2 = 4y +2/ -2
Answer: x=-2y-1

3x +4y =8
3x + 4y = -4y = 8+-4y
3x= -4y +8
Divided by 3
3x/3 = -4y + 8/3
x=-4/3y + 8/3

I have one qt of solution diluted out 1:4 How much do I need to add to end up with a final product that’s a 1:10 solution?
LenaWriter [7]

Answer:

1.1352 L

Step-by-step explanation:

L = qt 1.0567

qt = 0.946 L  

1:4 = 5

0.946/5 = 0.1892 L one part

0.1892 x 11 = 2.0812 11 parts as 1+10 =11

Answer therefore is subtracting 5 from 11 parts to get the final 6 parts added = 2.0812 - 0.946

= 1.1352 L

What is the equation in slope-intercept form of a line (y = mx + b) that has aslope of 3 y-intercept of 6?
arsen [322]

The equation of the line is y = 3x + 6

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the equation of the line?</h3>

The given parameters are

Slope, m = 3

y-intercept, c = 6

A linear equation is represented as

y = slope * x + y-intercept

i.e.

y = mx + c

So, we have

y = 3x + 6

Hence. the linear equation is y = 3x + 6

(02.01 MC) When a figure is translated on a coordinate grid, what conclusion can you draw from the pre-image and image?
Tanya [424]
Translation doesn't change the lengths of the sides or
the size of the angles. So when a figure is just translated,
the original image and the translated image are congruent.

Need help with this questsion answer as a dollar amount
makkiz [27]

Answer:

100,000,000,000

Step-by-step explanation:

10^6 = 1,000,000. So one million computer programmers.

They're all making 10^5. So 100,000.

1,000,000 * 100,000, since every single one is making 100k.

Therefore, $100,000,000,000 is your answer.

Remember not to include the dollar sign!
