Answer:
Slope = -4
Step-by-step explanation:
Given points are :
(-1,30) and (4, 10)
We need to find the slope of the line that passes through these points.
We know that, the formula for the slope of line is given by :

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10
Put values in the above formula.

So, the slope of the line is -4.

(9x^4-13x^3-x-7)+(7x^3-2x+1)=
9x^4-13x^3-x-7+7x^3-2x+1=
9x^4+(-13+7)x^3+(-1-2)x-7+1=
9x^4+(-6)x^3+(-3)x-6=
9x^4-6x^3-3x-6
Answer: Option <span>D.)9x^4−6x^3−3x−6</span>
The probability that none of the shoes are black is 51.2%.
If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.
0.8 x 0.8 x 0.8 = 0.512 = 51.2%
Answer:
B
Step-by-step explanation:
I believe that the answer to this question is B. I think this because I took 5.2 and divided it by 0.4 which gave me 13. I did 5.2 divided by 0.4 because it wanted to know how many times 0.4 goes into 5.2.
I hope this helps I am rlly srry if I am wrong. have a beautiful day.
