Please help solve: Graph y-4=2(x-2)
xeze [42]

Answer:

Graph y = 2x

Step-by-step explanation:

First, let's get the equation into standard form. Distribute the 2 on the right.

y-4=2x-4

Next, we want the variable "y" to be alone, so we at 4 to both sides.

y-4+(4)=2x-4+(4)\\\\y=2x

That is our equation in standard y = mx + b form. "m" is our slope, while "b" is our y-intercept. Above , we don't have a value for b, therefore the line passes through the origin.

We do, however, have a slope, which can be thought of as \frac{rise}{run} or rise over run. To represent this, we can rewrite our slope as:

y=\frac{2}{1}x

Meaning in each interval, the line goes up by 2 units, and moves forward by 1.

Mrs Hong had some milk. She used of it to bake some waffles and
Sergio [31]

<u><em>Answer:</em></u>

Mrs. Hong originally had 900 ml of milk

<u><em>Explanation:</em></u>

The complete question is in the attached image

Assume that the amount of milk Mrs. Hong originally had was x ml

<u>We are given that:</u>

1- She used \frac{1}{6} of it to bake the waffles, <u>therefore</u>:

   Amount used in baking waffles = \frac{1}{6}x ml

2- She used 300 ml to bake a pie

3- Amount left is half the original amount, <u>therefore</u>:

   Amount left = \frac{1}{2}x ml

<u>We know that:</u>

Total amount = amount used in waffles + amount used in pie + amount left

<u>Substitute with the givens and solve for x:</u>

Total amount = amount used in waffles + amount used in pie + amount left

x = \frac{1}{6}x + 300 + \frac{1}{2}x\\  \\x-\frac{1}{6}x-\frac{1}{2}x = 300\\   \\\frac{1}{3}x = 300\\  \\x = 300*3 = 900 ml

<u>This means that:</u>

She originally had 900 ml of milk

Hope this helps :)
