Answer:
Step-by-step explanation:
First substitue the coordinates to the equation so
x=9, y=2
you would get
2=-3/7(9) + b
we put b because we are trying to find the new slope
multiply the two numbers above
2=-3/6/7 + b
subtract the whole number from both sides
b= 5/6/7
in equation would be
y= -3/7 + 5/6/7
Let me know if there is an error.
Answer:
The area of the label is 
Step-by-step explanation:
step 1
Find the radius
we know that
The volume of the cylinder (can of tuna) is equal to

In this problem we have


substitute and solve for r

Simplify



step 2
<em>Find the lateral area of the can</em>
The lateral area of the cylinder (can of tuna) is equal to

we have



Answer:
Height of cylinder is
.
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:

So, radius, R =
feet
Let height of cylinder be
feet.
Formula for volume of cylinder is given by:

Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,

Using formula for volume, 

Hence, Height of cylinder is
.
Answer:
5 hours
Step-by-step explanation:
A motorcycle will complete the 540 mile trip in 11.25 hours
And the car will complete it 2.25 hours less, i.e 11.25 -2,25 = 9 hours.
then,
Speed of the car:
60t + 48t = 540
108t = 540
If you Divide both sides by 108 we get t = 5
So, they will meet in 5 hours,
Answer:
See Below
Step-by-step explanation:
x(2x) - 4(2x) + x(3) - 4(3)
= 2x² - 8x + 3x -12
= 2x²-5x-12
