Answer:

y = -2, y = -5, x = 20, x = -12

Step-by-step explanation:

When dealing with unknown y values, rearrange the equation so that y is isolated:

y + 5 = x/4 >>> subtract 5 from both sides >>> y = x/4 - 5

Now, substitute in your values for y in the table:

12/4 - 5 = -2

0/4 - 5 = -5

Now, to deal with unknown y values, rearrange so that y is instead isolated:

y + 5 = x/4 >>> multiply both sides by 4 >>> 4y + 20 = x

Substitute!

4(0) + 20 = 20

4(-8) + 20 = -12

Bob had three carries of 8 yards each and 5 carries of 6 yards each in a recent football game. what was rushing average(average

Sedaia [141]

3 carries of 8 yds.....3 * 8 = 24 yds
5 carries of 6 yds.....5 * 6 = 30 yds

so we have a total of 8 carries for 54 yds..

54/8 = 6.75 <== average yds per carry

3. A cone has a heighth and a base with radius r. You want to change the cone so its volume is tripled. What is the new height i

Sphinxa [80]

Answer:

Hence the new height is 3 times the original height .(h1=3h)

Step-by-step explanation:

Given:

A cone with has height and base with radius r .

To Find:

What is new height

Solution:

Consider as cone with height h base radius r, and volume v

Here given that only height changes for the cone i.e. r remains the unchanged or same or constant

The volume for a regular cone is given by ,

$V=pie*r^2*h/3$

Here V is directly proportional to h i.ee pie ,3 and r being constant

$V=K*h$

i.e V/h=constant

V1 and h1 are new dimensions for new cone

V/h=V1/h1

Here V1=3V

So V/h=3V/h1

1/h=3/h1

i.e h1=3h

Hence the height is 3 times the original height .

2=ln(x+7) solve for x

maria [59]

Answer:

e^2 -7 = x

Step-by-step explanation:

2=ln(x+7)

Raise each side to the base of e

e^2 = e^ln (x+7)

The e^ln cancel

e^2 = x+7

Subtract 7 from each side

e^2 -7 = x +7-7

e^2 -7 = x
