Can someone teach me how to do this im a good learner i just missed days
mrs_skeptik [129]
I’m not very good at explaining but if we explain from the beginning the equation is y=m(x)+b and m means the slope while b means y- intercept so all you have to do is substitute these variables with the numbers in the problem basically it would be y=10x+10 also the picture attached is how you graph it. Hope this helped:)

Fill in the missing number to complete the factorization<br> x3 + x2 - 21x - 45 = (x + 3)(x - 5)(x +
Olin [163]

Answer:

3

Step-by-step explanation:

Let the missing number be k.

Then we have x^3+x^2-21x-45=(x+3)(x-5)(x+k)

We expand the right hand side to get:

x^3+x^2-21x-45=x^3+kx^2-2x^2-2kx-15x-15k

By comparing constant terms we get:

-15k=-45

Divide both sides by -15

k=\frac{-45}{-15}=3

Therefore the missing number is 3

8p + 10p – p – 8p + 5 = 50
Lemur [1.5K]
The answer is p = 5.

Here are the steps I did.

1. Simplify 8p + 10p - p - 8p + 5 to 9p + 5 ( 9p + 5 = 50)

2. Subtract 5 from both sides ( 9p = 50 - 5)

3. Simplify 50 - 5 to 45 ( 9p = 45)

4. Divide both sides by 9 ( 45/9)

5. Simplify 45/9 to 5 ( p = 5)
