Set x equal to 1 then solve

y =  - 1 + 6
y = 5
then

y = 3 \times 1 + 2
y = 5

Answer:

y = -1 + 6 = 5

Step-by-step explanation:

Because they are both solved for y, set the equations equal to each and solve for x:

-x + 6 = 3x + 2

6 - 2 = 3x + x

4 = 4x

1 = x

Substitute the x-value, 1, into one of the original equations to find the y-value:

y = -1 + 6 = 5

The solution is the point (1, 5).

we know that

The volume of a cylinder is given by the formula

V=\pi r^{2} h

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

r=x+8\\ h=2x+3

Substitute the values in the formula above

V=\pi*(x+8)^{2}*(2x+3)

V=\pi*(x^{2}+16x+64)*(2x+3) \\ V=\pi *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=\pi *(2x^{3} +35x^{2} +176x+192)

therefore

the answer is

The volume of the can is equal to

V=\pi *(2x^{3} +35x^{2} +176x+192) units ^{3}

Please help me no clue about this
Lena [83]
Ok....sooo. first. you do a line and number it.
--------------1-------------2-----
as you see the first number in the graph is 1.5 sooo it goes in between number 1 and 2 because its in the middle.
The second is 1.6 sooo this number goes next to 1.6
-------------1--------1.5---1.6-----------------2----------
then you repeat the same with the other.
now idk if this answer the question but i hope someone else makes sure its correct

three neon lights are turnd on at the same time one blinks every 5 second the second every 12 and the third every 6 seconds in 5
mylen [45]

Answer:

5 times

Step-by-step explanation:

If we have to determine the number of times the lights will blink at the same time, we have to find Least common multiple (L.C.M) of 5, 12, and 6 seconds.

5 = 1 x 5

12 = 1 x 2 x 2 x 3

6 = 1 x 2 x 3

The L.C.M of 5, 6, and 12 is = 2 x 2 x 3 x 5 = 60

The three lights will be turned on after 60 seconds or 1 minute.

The lights will be turned on in 1 minute       1 time

The lights will be turned on in 5 minutes    (1*5) times = 5 times
