Answer:
<h3>D. p2 + 27p > 770</h3>
Step-by-step explanation:
Ms. Winter wants to have 27 more rows than people in each row.
The number of people in each row is represented by p.
The number of rows is represented by p + 27.
Ms. Winter wants to have more than 770 people in the march.
To find the total number of people in the march, find the product of the rows and the people in each row.
Set up an inequality to represent the situation.
p(p + 27) > 770
p2 + 27p > 770
Answer:
284.24
Step-by-step explanation:
by multiplying 0.68 to 418 we get 68% of 418
Step-by-step explanation:
1. We we can split 4p into 9p - 5p, and now we have 3p² + 9p - 5p - 15 = 0. We can take out 3p from the first 2 terms and -5 from the last 2 terms. This gets us 3p (p + 3) -5 (p + 3) = 0. These two terms have (p + 3) as a common facor, so we can take that out as well, which give us (p + 3)(3p - 5) = ). Using Zero Product Property, p + 3 = 0 and 3p - 5 = 0, and when we solve each equation, we get p = -3, p= 5/3.
2. We will use the same process.
6x² + 14x - 3x - 7 = 0
2x (3x+7) - 1 (3x+7) = 0
(3x + 7)(2x - 1) = 0
3x + 7 = 0, 2x - 1 = 0
x = -7/3, x=1/2
Hope this helps!
Answer:
y=2x-2
Step-by-step explanation:
y=mx+b is point slope form.
let m= the slope
b=y intercept
the y intercept is -2
y=mx-2
then after finding the slope (2) put that in
y=2x-2
