The first two steps in determining the solution set of the system of equations y=x to the second power -2x-3 and y=-x+3
Arisa [49]

The solution set for the both equation is  (3,0) and (-1,0)

We have given that the equation

y=x^2-2x-3 \ and\  y=x+3

We have to determine the solution to the first equation

<h3>What is the quadratic equation formula?</h3>

\quad x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:1\cdot \left(-3\right)}}{2\cdot \:1}

x_{1,\:2}=\frac{-\left(-2\right)\pm \:4}{2\cdot \:1}

x_1=\frac{-\left(-2\right)+4}{2\cdot \:1},\:x_2=\frac{-\left(-2\right)-4}{2\cdot \:1}

x=3,\:x=-1

Now  use this value we have to find the value of y

When x=3 then

y=(3)^2-2(3)-3

y=9-6-3

y=0

When x=-1 then y=1-2(-1)-3

y=1+2-3

y=0

Therefore the solution set for both equations is (3,0) and (-1,0).

1. Find the slope of a line passing through points (0,0) and (4,5)
olya-2409 [2.1K]

Answer:

slope = \frac{5}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (4, 5)

m = \frac{5-0}{4-0} = \frac{5}{4}

a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage
Verdich [7]

Answer:

25 years.

Step-by-step explanation:

Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:

5 x 5 = 25

25 + 15 = 40

40/2 = 20

5 + 15 = 20

Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.
