Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.
mamaluj [8]

Answer:

The height of the candle after 7 hours is 21.3 centimeters.

Step-by-step explanation:

From the information given you can assign the following values:

x1=10; y1=21

x2=28; y2=19.2

First, you have to find the slope using the following formula:

m=\frac{y2-y1}{x2-x1}

m=\frac{19.2-21}{28-10}

m=-0.1

Then, you can find the equation using the point/slope formula:

y-y1=m(x-x1)

y-21=-0.1(x-10)

y-21=-0.1x+1

y=-0.1x+22

Finally, to find the answer you need to replace the value of x that would be 7 in y=-0.1x+22:

y=-0.1(7)+22

y=-0.7+22

y=21.3

According to this, the height of the candle after 7 hours is 21.3 centimeters.

Angle TVZ makes a linear pair with angle ZVW so the measure of angle TVZ plus the measure of angle ZVW=180 degrees. Angle ZVW is
ss7ja [257]

Answer:

Step-by-step explanation:

2x +15 +2x +5 = 180

4x = 180 - 20

x = 160/4

x = 40

TVZ + 2x +5 =180

TVX +2(40) = 180 -5

TVX = 175 - 80

TVX = 95

Which set does not contain –3?
svet-max [94.6K]
A real number is any number that is rational, including integers and natural numbers. A rational number is any number that can be written as a ratio or isn't a square root of a number. An integer is any whole number (not including fractions) that exists, negative or positive. A whole number is the same as an integer except it only includes positive numbers. 
Since a set of whole numbers wouldn't be able to include any negative numbers, your answer would be your fourth option. 
Hope this helped you out! :-)
