Solve x²-x-30=0 using the factorisation method.​
Furkat [3]

Answer:

Step-by-step explanation:

x²-x-30=0

x² - 6x + 5x - 30 = 0

(x² - 6x) + (5x - 30) = 0

x(x - 6) + 5(x - 6) = 0

(x + 5)(x - 6) = 0

x + 5 = 0 or x - 6 = 0

x = -5 or x = 6

Write the slope-intercept form of the equation of each line.
miskamm [114]

Answer:

y = 3x + 2

Step-by-step explanation:

Let's identify two clear points on this line. I can see (0, 2) and (-1, -1)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-1 - 2) / (-1 - 0)

Simplify the parentheses.

= (-3) / (-1)

Simplify the fraction.

-3/-1

= 3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = 3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the first point (0, 2). Plug in the x and y values into the x and y of the standard equation.

2 = 3(0) + b

To find b, multiply the slope and the input of x(0)

2 = 0 + b

Now, we are left with 0 + b.

2 = b

Plug this into your standard equation.

y = 3x + 2

This is your equation.

Hope this helps!
