Answer:

(-4,1) because if the x value repeats the relation is no longer a function

Answer:

(-4,1)

Step-by-step explanation:

In the table under the X column there is already a -4 so if you added (-4,1) to the table it would no longer represent a function because a function cannot have more than one of the same x values.

Hope this helps.

Leigh bought a conical candle wax mold. The height of the mold is 18.9 inches and the radius of the inside of the top of the con

ICE Princess25 [194]

Answer:

87.28 cubic inches

Step-by-step explanation:

Leigh wants to fill the conical candle wax mold completely with candle wax.

We have to calculate the volume of the cone by the formula :

$V=\pi r^2\frac{h}{3}$

Here, V = volume

r = radius = 2.1 inches

h = height = 18.9 inches

By substituting these values given, into the formula

$V=\pi (2.1)^2(\frac{18.9}{3})$

= (27.783)π

= 87.28 inch³

Conical mold can hold 87.28 inch³ candle wax.

lilavasa [31]

Answer:

27 of the pets are dogs.

Step-by-step explanation:

Real easy way to do this, treat 45 (the total) as 100. So, do 45/100 then multiply the result of that by 60, and you end up with 27.

45/100=0.45

0.45*60=27

Find the slope of the line

Inessa05 [86]

The two points (0,0) and (4,5) are on the line. The points are marked in blue in the attached image below.

Use the slope formula to get

m = (y2-y1)/(x2-x1)

m = (5-0)/(4-0)

m = 5/4 <----- this is the answer in fraction form

m = 1.25 <----- this is the answer in decimal form

The idea of the slope formula is we're subtracting the y values together, then subtracting the x values together in the same order, finally we divide the two results and reduce if possible to get the fraction form. Use long division or a calculator to find the decimal form of the fraction. In this case, the rise is 5 and the run is 4. Meaning we go up 5 units and over to the left 4 units to go from (0,0) to (4,5).
