What is the solution of the linear-quadratic system of equations?<br><br> {y=x^2+5x−3<br> {y-x=2
Rina8888 [55]

Answer: the above stated equation is a quadratic equation

Step-by-step explanation:

Given the following equations

y = x^2 + 5x - 3....equation 1

y-x = 2

y = x + 2........equation 2

Let equation 1 equal equation 2

x^2 + 5x -3 = x + 2

Bringing the equation to one side and equating to zero

X^2 +5x - 3 -x -2 = 0

X2 + 5x -x -3 -2 = 0

X^2 + 4x -5

Solving the aquatic equation

(x + 5)(x -1) = 0

X + 5 = 0

X1 = -5

X- 1 = 0

X2 = 1

To prove:

Substitute the values for x1and x2 into the equation x^2 + 4x - 5 = 0

Answer:

1. Fala can paint more than one whole step

2. She can paint 3 steps

Step-by-step explanation:

1.  In the second question we found that she has enough for 3 steps and 3 is more than 1 so she can paint more than one step

2. 6/4=12/8 so she has 12/8 quarts and needs 4/8 for each step

Divide 12 by 4 = 3  So she has enough paint for 3 steps
