Nick is solving the equation 3x^2=20-7x with the quadratic formula which values could He use for a, b and c

Answers

Answer:

C. a = 3

b = 7

c = -20

Step-by-step explanation:

x = -b+/- (sq) b^2 - 4ac.

Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0

S if you use your equation : 3x^2 = 20 - 7x

First you have to move everything to one side.

So it'll look like this:

3x^2 = 20 - 7x

-20 -20

3x^2 - 20 = -7x

+7x +7x

3x^2 - 20 + 7x = 0

don't forget that... Ax^2 +Bx+ C= 0

3 = A

7 = B

-20 = C

Hugh has to earn at least $400 to meet his fundraising goal. He has only 100 books that he plans to sell at $8 each. Which inequality shows the number of books, x, Hugh can sell to meet his goal?

Answers

If you would like to find the inequality that shows the number of books Hugh can sell to meet his goal, you can do this using the following steps:

x = ? ... the number of books
$8 * x >= $400
8 * x >= 400
x >= 400 / 8
x >= 50 books

The correct result would be: $8 * x >= $400.

Answer:

50 ≤ x ≤ 100

Hello,

Answer C : 2x+5y=-15

Indeed:

y+7=-2/5(x-10)
==>y+7=(-2x/5+20)/5
==>5(y+7)=-2x+20
==>5y+35=-2x+20
==>2x+5y=20-35
==>2x+5y=-15
