Answer: ![-3x^{2} y\sqrt[3]{2y}](https://tex.z-dn.net/?f=-3x%5E%7B2%7D%20y%5Csqrt%5B3%5D%7B2y%7D)
Step-by-step explanation:
It is the same as multiplying by 2/3, the equation being 2/3n n being the number
Jason: 5/7
Sara: 4/5
Think of it this way: if the total track is a mile, and Jason runs 5/7 of it, he has run 5/7 of a mile. Then Sara runs 4/5 OF 5/7, with "of" meaning "times," so she runs 4/5 x 5/7, which gives you 20/35, which simplifies to 4/7. You can also think of Sara's distance as 80 percent of Jason's. If she runs "80 percent of the sevenths that Jason ran," that means she ran 4 out of his 5 sevenths.
There is no solution since they are both adding $10 to their accounts every week.
Answer:
D
Step-by-step explanation:
y>-3x+1 Negative slope
y<u><</u>x+2 Positive slope
< or > have dotted line
<u><</u> or <u>></u> have a solid line
> or <u>></u> means solutions are above the line
< or <u><</u> means solutions are below the line
The one with negative slope has a dotted line and solutions above it.
The one with positive slope has a solid line and solutions below it.
