frozen [14]3 years ago
5 0

Answer:

x = -5

Step-by-step explanation:

The equation y = x^2+10x+25  can be factored to (x+5)^2

when (x+5)^2 = 0

x = -5

meaning the equation has a line of symmetry at x = -5

Model with mathematics. Hamid has read 60 pages of the book
vagabundo [1.1K]

Answer:

Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Step-by-step explanation:

Given that Hamid has read 60 pages of the book he will be using for a book report, if he reads 45 pages per hour, to determine how many hours will it take him to read at least 375 pages of the book the following calculation must be done:

375/45 = X

8.3333 = X

0.333 x 60 = 20

Thus, Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Why would you need inequalities?
77julia77 [94]

Answer:

An inequality is a mathematical expression that contains inequality signs. For example, y≤ 12x is an inequality. Inequalities are used to tell us that an expression is either larger or smaller than another expression. Equations and inequalities can contain both variables and constants.

The table shows a pattern of exponents.<br><br> What is the pattern as the exponents decrease?
Marrrta [24]

Answer:

Option C is correct.

Step-by-step explanation:

We need to find the pattern as the exponent decreases.

the first value in the table is 125.

if we divide 125 by 5 i.e 125/5 we get 25

the next value in the table is 25

if we divide 25 by 5 i.e 25/5 we get 5

the next value in the table is 5

if we divide 5 by 5 i.e 5/5 we get 1

the next value in the table is 1

if we divide 1 by 5 i.e 1/5 we get 1/5

the next value in the table is 1/5

if we divide 1/5 by 5 i.e 1/5*5 we get 1/25

the next value in the table is 1/25

So, the pattern is if we divide the previous value by 5 we get the next value in the table.

So, Option C is correct.
