(Note: this is hard to explain without graphing. You might want to graph both of these lines just to make sure I did this correctly. :))

Y = -4(x) is the y = mx + b where m = slope and b = the y intercept.

So the slope of line A is -4 / 1 and the y intercept is 0. (If it's 0 there is no point in writing it down, so it was left out of the equation.)


The slope of line B with be equal to the slope of line A, so we can fill that in our equation. y = -4 x + ??

We know that y increases as x decreases.

Now we just need to scale 8, -3 down until x = 0.
 (8 - 4, -3 + 1) = (4, -2) 

(4 - 4, -2 + 1) = (0, -1)

y = -4x -1 is your final answer. Hope that helps! :)

Lynna [10]

Answer:

11 6/9

Step-by-step explanation:

Daniel works in a market

He has large bags of potatoes that weighs 26 1/4

Daniel is going to sell them in smaller bags 9/4 pounds each

Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows

= 26 1/4 ÷ 9/4

= 105/4 ÷ 9/4

= 105/4 × 4/9

= 105/9

= 11 6/9

What is the answer of this equation ? 10x-6(2x+5)=20
Rudiy27

Answer:

Simplifying

x = -25

Step-by-step explanation:

Reorder the terms:

10x + -6(5 + 2x) = 20

10x + (5 * -6 + 2x * -6) = 20

10x + (-30 + -12x) = 20

Reorder the terms:

-30 + 10x + -12x = 20

Combine like terms: 10x + -12x = -2x

-30 + -2x = 20

Solving

-30 + -2x = 20

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '30' to each side of the equation.

-30 + 30 + -2x = 20 + 30

Combine like terms: -30 + 30 = 0

0 + -2x = 20 + 30

-2x = 20 + 30

Combine like terms: 20 + 30 = 50

-2x = 50

Divide each side by '-2'.

x = -25
