What are the values of a, b, and c in the quadratic equation 0 = x2 – 3x – 2?

The answer is b

Step-by-step explanation:

General form is ax^2 + bx + c = 0

so comparing the equation in the question to this we get:-

a = 1, b = -3 and c = -2 Answer

The system of equations is

5p+2w=7.753p+4w=10.95.

When solved

The cost of one watermelon(w) is $2.25The cost of one peach(p) is $0.65

Step-by-step explanation:

Let the price of one peach =p

Let the price of one watermelon=w

On Monday, bought 5 peaches and 2 watermelons for $7.75.

5p+2w=7.75

On Thursday, Josh went back to the Farmer's Market and bought 3 peaches and 4 watermelons for $10.95.

3p+4w=10.95.

The system of equation that could be used to solve for the price of one peach (p) and one watermelon (w) is therefore:

5p+2w=7.753p+4w=10.95.

To solve this, Multiply the first equation by 4 and the second equation by 2.

20p+8w=316p+8w=21.9

Subtract

14p=9.1

Divide both sides by 14

p=$0.65

Next, we substitute p=$0.65 in any equation to obtain w.

5p+2w=7.75

5(0.65)+2w=7.75

2w=7.75-3.25

2w=4.5

w=$2.25

Therefore:

The cost of one watermelon(w) is $2.25The cost of one peach(p) is $0.65
