Write the equation of the graph​
lakkis [162]

Answer:

y = x -3

Step-by-step explanation:

From the graph we see the line goes from point (0, -3) to point ( 3, 0), so we can find the slope as m= rise ( go up 3)  / run ( go to the right 3)  = 3/ 3 = 1

From the graph we can also see the y-intercept ( where the line intersects the y axis is at b = -3

The general equation of the line is y= mx+ b

Our line's equation is y = x -3, because m=1 and b= -3

Solve the following quadratic equation for all values of x in simplest form. 7+2x^2=11​
ollegr [7]

Answer:

x=-\sqrt2\text{ or } x=\sqrt2

Step-by-step explanation:

We have:

7+2x^2=11

To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:

2x^2=4\\

Divide both sides by 2:

x^2=2

Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:

x=\pm\sqrt2

Therefore, our solutions are:

x=-\sqrt2\text{ or } x=\sqrt2
