The temperature in Coldspot is -7o F and increasing 2.5o per hour. The temperature in Frostberg is 19 degrees F and decreasing 4 degrees per hour.
a. How long will it be until the temperatures are the same?
b. What will the temperature be then?

Answers

Answer:

It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.

Step-by-step explanation:

Coldspot = -7 + 2.5x

Frostberg = 19 - 4x

First, we are going to input our values into the variable in a table.

          Coldspot                            Frostberg

1     -7 + 2.5(1) = -4.5                    19 - 4(1) = 15

2     -7 + 2.5(2) = -2                     19 - 4(2) = 11

3     -7 + 2.5(3) = 0.5                   19 - 4(3) = 7

4     -7 + 2.5(4) = 3                      19 - 4(4) = 3

It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.

Hope this Helps! :)

Which statement is true about the ordered pair (3 , 4)?

Answers

Answer:

Move three units left on the x axis and 4 units up on the y axis from the origin

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

That is because ordered pairs are written as (x,y) and for the ordered pair (3,4), 3 is x and 4 is y. The x-axis is the horizontal (left and right) line, the y-axis is the vertical line (up and down). The numbers are positive, so you go 3 units right and 4 units up.

Answer:

Incorrect

Step-by-step explanation:

Use PEMDAS

Solve one side of the equation first

-21 × -4 + - 6

negative × negative = positive

84 + - 6

positive + negative = negative

84 - 6

78

Now solve the other side of the equation

-21 × -4 + (-21) × (-6)

negative × negative = positive

-21 × -4 + (126)

negative × negative = positive

84 + 126

210

Does 78 = 210?

No, so we can assume this equation is incorrect

Marco has saved $279 for karate lessons. He bought a uniform for $56 and pays $14 per class. Which inequality represents the number of classes, c, Marco can take and stay within his budget

Answers

Answer:

B.

Step-by-step explanation:

Since the main goal for Marco is to stay under his budget which is 279, it's expected that he would want to spend less than or equal to his budget and that is the point to spend less than our goal of spending limit. If the cost of uniform and the cost of each of his classes are less than how much money he wants to spend, than that is going to still be within his budget even if the equation equals to 279 it is still within his budget anything greater would be consider over spending past his budget. Therefore making all other equations false.

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given a graph of a function f(x).

The graph is a straight line where there is a unique value of y for each value of x.

We have to calculate the value of x when y = 7.

Taking the y coordinate to 7, the x coordinate corresponding to the y coordinate is 5.

Hence the value of x is 5.
