Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling. Abha collected 178

dangina [55]

Answer:

$2S+178\ge 2,000,$

$[911,\infty).$

Step-by-step explanation:

Let S be the number of cans that Shane had collected.

Abha had collected 178 more cans than Shane did, then Abha had collected S+178 cans.

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling, this means that

$S+S+178\ge 2,000,\\ \\2S+178\ge 2,000.$

Solve this inequality:

1. Divide it by 2:

$S+89\ge 1,000.$

2. Now

$S\ge 1,000-89,\\ \\S\ge 911.$

The solution set is $[911,\infty).$

Help with math pls cant figure it out

tatyana61 [14]

Answer:

$\frac{5}{4}+or-\frac{3i\sqrt{7} }{4}$

Step-by-step explanation:

You can solve this equation with the quadratic formula which is:

$m_{1,2}=\frac{-b+or-\sqrt{b^{2}-4ac } }{2a}$

All you need to do is rearrange the equation (add $-\frac{11}{2}$ to both sides and then multiply both sides by 2) to get:

$2m^2-5m+11=0$

From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:

$m_{1,2}=\frac{5+or-\sqrt{(-5)^{2}-4(2)(11) } }{2(2)}$

That simplifies to:

$\frac{5}{4}+or-\frac{\sqrt{25-88} }{4}$

Which simplifies even further to:

$\frac{5}{4}+or-\frac{\sqrt{-63} }{4}$

Which gets you:

$\frac{5}{4}+or-\frac{3i\sqrt{7} }{4}$

P.S. The plus-minus sign wasn't working for me, so I had to just write, "+or-". I hope that didn't make it too confusing for you.

P.P.S. Hope this helps :) Don't forget to mark Brainliest if it did.
