X² + 10x + 25 = 16

x² + 10x + 25 - 16 = 0
x² + 10x + 9 = 0

(x + 1)(x + 9) = 0

x(x+9) + 1(x+9) = 0
x² + 9x + x + 9 = 0
x² + 10x + 9 = 0


(x + 1) = 0
x = -1

(x + 9) = 0
x = -9

Write an equation in slope-intercept form (y = mx + b).
Wewaii [24]

Answer:

y = 2/7x + 7

Step-by-step explanation:

We start off by putting the original equation into slope-intercept form. Subtract 7x from both sides, then divide both sides by -2. Your new equation should be y = -7/2x - 8. It's important to know that when two lines are perpendicular, their slopes (m) are opposite reciprocals of each other.  So -7/2 becomes 2/7. The first part of your final equation is y = 2/7x + b.

Next, we need to find the y intercept (b). You need to plug the x and y values from the given coordinate point (-7,5) into your final equation. You should end up with: 5 = 2/7(-7) + b. Then, solve for b.

5 = -14/7 + b

5 = -2 + b

7 = b

Finally, plug the b value into your final equation and you will have your answer.

This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each
Georgia [21]

Answer:

The total number of pages in all the newspaper is 390,625 pages

Step-by-step explanation:

The number of pages in the newspaper = 25 pages

The number of schools ordering the newspaper = 25 schools

The number of class rooms in each school = 25 classrooms

The number of students in each classroom = 25 students

Therefore;

The total number of pages in all the newspaper = 25 pages per paper × 25 schools × 25 classroom per school × 25 students per classroom

The total number of pages in all the newspaper = 25 × 25 × 25 × 25 = 25⁴

The total number of pages in all the newspaper = 25⁴ = 390,625 pages
