Rewrite the equation 2x+6x^(2)-1=3x^(2) in standard form and identify a, b, and c.

Fed [463]

Hi there!

$2x + 6 {x}^{2} - 1 = 3 {x}^{2}$
First subtract 3x^2 from both sides.

$2x + 3 {x}^{2} - 1 = 0$
Now rearrange the equation.

$3 {x}^{2} + 2x - 1 = 0$
Finally we can see our answer.

$a = 3$
$b = 2$
$c = - 1$

A jacket costs 50$ at the store Evan has a coupon for 15$ off.Max pays only 0.6 of the price because his father works at the sto

Arturiano [62]

Answer:

Step-by-step explanation:

The original price of the jacket at the store is $50.

Evan has a coupon for 15$ off. This means that the amount that Evans will pay is the original price - 15% of the original price. It becomes

50 - (15/100 × 50) = 50 - 7.5 = $42.5

Max pays only 0.6 of the price because his father works at the store.

This means that the amount that Max will pay is 0.6 × the original price. It becomes

0.6 × 50 = $30

Max will pay the least amount because his amount is smaller
