Answer:

The second stove had a higher temperature when the stoves were turned off.

The first stove cooled down at a faster rate.

Step-by-step explanation:

first stove: T(t) = 180 - 2.55t can also be written as T(t) = -2.55t + 180

(180 is the y-intercept; -2.55 is the slope)

second stove = T(t) = mt + 200

(0,200) (40,130)

$\frac{200 - 130}{0 - 40}$ = $\frac{60}{-40}$ = $\frac{3}{-2}$ = -1.5

T(t) = -1.5t + 200

x represents a certain number. when the number is multiplied by 3 the result is the same as adding 34 to the number x

Rus_ich [418]

Answer:

3x = 34 + x

x = 17

Step-by-step explanation:

First it says that 3 is multiplied with the number (x)

So, we have : 3x

Then, it says that those numbers multiplied will be equal to adding 34 to x

So, 34 + x

Since the problem says that those terms are equivalent we have to join both terms by an equal sign like this:

3x = 34 + x.

Then solve for x:

3x = 34 + x

3x - x = 34

2x = 34

x = 34/2

x = 17

A diameter is a straight line passing through a circle from side to side.

Based on your question, a diameter would be E and J. As you can see, E is on one side, and J is on the other, and they make a straight line through the center of the circle.

Problem 1

<h3>Answers: n = 3 or n = 5</h3>

---------------

Work Shown:

$|4n - 15| = |n|\\\\4n - 15 = n \ \text{ or } \ 4n-15 = -n\\\\-15 = n-4n \ \text{ or } \ -15 = -n-4n\\\\-15 = -3n \ \text{ or } \ -15 = -5n\\\\-3n = -15 \ \text{ or } \ -5n = -15\\\\n = \frac{-15}{-3} \ \text{ or } \ n = \frac{-15}{-5}\\\\n = 5 \ \text{ or } \ n = 3\\\\$

==============================================

Problem 2

<h3>Answers: c = 1 or c = -2/3</h3>

-----------------------

Work Shown:

$|2c+8| = |10c|\\\\2c+8 = 10c \ \text{ or } \ 2c+8 = -10c\\\\8 = 10c-2c \ \text{ or } \ 8 = -10c-2c\\\\8 = 8c \ \text{ or } \ 8 = -12c\\\\8c = 8 \ \text{ or } \ -12c = 8\\\\c = \frac{8}{8} \ \text{ or } \ c = \frac{8}{-12}\\\\c = 1 \ \text{ or } \ c = -\frac{2}{3}$
