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.
Answer:
V≈339.3
Step-by-step explanation:
Formula for volume of a cylinder is
V=πr2h
if you plug in the numbers you get V≈339.29
Multiplication Identity property
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
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:


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

Moving all terms to the left side:

Simplifying:

Factoring:

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
