What is the solution of the linear-quadratic system of equations? { y = x 2 + 5 x − 3 y − x = 2
photoshop1234 [79]

Try substituting those values, and you will see they do not fit either equation.

looking at the 2nd equation, y = x+2, so

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

x^2 + 4x - 5 = 0

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

x = -5 or 1

so, y = -3 or 3

the solutions are thus (-5,-3)(1,3)

Hope this helps

7. Using the distance formula, calculate how far Hector threw the ball. (4 points: 2
iragen [17]

The required distance covered is 90 units

<h3>Distance formula</h3>

The formula for calculating the distance between two points is expressed as shown:

  • D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The required coordinates missing are (0, 42.78) and (90.42.78). Substiute the coordinate into the formula:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

D=\sqrt{(42.78-42.78)^2+(90-0)^2}\\D=\sqrt{(0^2+(90)^2}\\D = 90 units

Hence the required distance covered is 90 units
