y = - 7x - 20

the equation of a line in ' slope- intercept form ' is

y = mx + c → (m is the slope and c the y- intercept)

here m = - 7 ⇒ y = - 7x + c

to find c substitute ( - 4 , 8 ) into the equation

8 = 28 + c ⇒ c = 8 - 28 = - 20

y = - 7x - 20 → equation in slope- intercept form

The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

In the triangle ABC, AB = BC = 8. Triangle ABC is an isosceles triangle and ∠B = ∠C = 30° (base angles are equal).

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

∠A + 30 + 30 = 180

∠A = 120°

The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.

X^2-4x+6x-24 factored

Lynna [10]

Answer: (X+6)(x-4)

Step-by-step explanation:

x^2-4x+6x-24 ==> x^2+2x-24

*Find two numbers that multiplied gives you -24 and add up to 2*

(6)(-4)= -24 6-4=2

Final result= (x+6)(x-4)

Using complete square to slove for x in the equation (x+7) (x-9)=25

Brrunno [24]

Answer:

$x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}$

Step-by-step explanation:

Apply Distributive property:

$(x+7)(x-9)=25\\\\x^2-9x+7x-63=25$

Add like terms and then add 63 to both sides of the equation:

$x^2-2x-63=25\\\\x^2-2x-63+63=25+63\\\\x^2-2x=88$

Pick the coefficient of the x term, divide it by 2 and square it:

$(\frac{2}{2})^2=1$

Add it to both sides of the equation:

$x^2-2x+1=88+1$

Rewriting the left side as a squared binomial, we get:

$(x-1)^2=89$

Apply square root to both sides:

$\sqrt{(x-1)^2}=\±\sqrt{89}\\\\x-1=\±\sqrt{89}$

And finally we need to add 1 to both sides of the equation. Then we get:

$x-1+1=\±\sqrt{89}+1\\\\x=\±\sqrt{89}+1\\\\\\x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}$
