Slope = (25 - 13)/(-7 + 4) = 12/-3 = -4
passing through the points (-7, 25) and (-4, 13)
y = mx+ b
13 = -4(-4) + b
b = 13 - 16
b = -3

equation
y = -4x - 3

hope it helps

The answer is D. She mixed up the slope and y-intercept when she wrote the equation in step 3.

I took the quiz and got it correct. Hope this helps

Given: m∠AOC = 120°, m∠BOD = 150°. Find: m∠BOC.

Molodets [167]

angleBOC = 270°

All 3 angles meet at O thus

angleBOC = angle AOC + angle BOD = 120° + 150° = 270°

What is the factored form of x^12y^18+1

Black_prince [1.1K]

Answer: The required factored form of the given expression is

$(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$

Step-by-step explanation: We are given to find the factored form of the following algebraic expression:

$E=x^{12}y^{18}+1.$

We will be using the following formula:

$a^3+b^3=(a+b)(a^2+ab+b^2).$

Now, we have

$E\\\\=x^{12}y^{18}+1\\\\=(x^4y^6)^3+1^3\\\\=(x^4y^6+1)\{(x^4y^6)^2-x^4y^6\times1+1^2\}\\\\=(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$

Thus, the required factored form of the given expression is

$(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$
