jasenka [17]
Okay. So 90 yds was cut from the 230 yd yarn. 230 - 90 = 140. 1/2 of 140 is 70. 230 - 70 = 160. The yellow yarn was 160 yds longer than the blue yarn at first.

1) The slope is 2
You can find this by finding this rise over run which is essentially counting from one point to the next

2) y intercept is 6
You can tell because when the x axis is at 0, the point is at 6 for the y-axis

3) Now that you have the slope and y intercept the answer is:
Y=2x+6

What is it? A or B I've been stuck for a while please help
AlladinOne [14]

Answer:

<em>Correct choice: B</em>

Step-by-step explanation:

<u>System of non-linear equations</u>

It's given the following system of equations:

y=x^2+3x+5

y=x+13

We'll use the substitution method. Substituting y from the first equation into the second equation, we have:

x^2+3x+5=x+13

Moving all terms to the left side:

x^2+3x+5-x-13=0

Simplifying:

x^2+2x-8=0

Factoring:

(x+4)(x-2)=0

There are two solutions:

x=-4, x=2

The first solution gives a value for y:

y=-4+13=9

First solution: (-4,9)

The second solution gives a value for y:

y=2+13=15

Second solution: (2,15)

Correct choice: B
