What is the missing x-value if (x,1) is a solution of 2x-y=5?

1 answer:

8 0

Equation of 2x-y= 5 where we know the y value from (x,1)

We substitute the y value in the equation to get the x value easily

2x-1= 5
2x = 5 + 1
2x = 6
x = 3 (divide both side by 2)

Answer x = 3 when y = 1

Simplify 8x^4/x^3+7x^4 and Find the excluded values

Maksim231197 [3]

So first what we do is we need to get the excluded values. So to get them we have: 8x^4/x^3+7x^4.

Lets factor out the second part. x^3+7x^4 = (x^(3/4)+7x))^4

So then we get 8x^4/(x^(3/4)+7x)^4

8x^4/(x^(3/4)+7x)^4

Answer:

$1,680\ g$

Step-by-step explanation:

we know that

Brenda requires 480 grams of couscous for 4 people

using proportion

Find out how many grams of couscous she requires for 14 people

Let

x -----> the amount of grams

$\frac{480}{4}\frac{g}{people}=\frac{x}{14}\frac{g}{people} \\\\x=14*480/4\\\\x=1,680\ g$

. What does the line y = 3x - 7 look like

Norma-Jean [14]

<span>y = 3x - 7

3 = slope
-7 = y intercept

This line would cross the y intercept at -7, and go up by 3 (slope). </span>
