Find the equation of the line parallel to the graph of 4x-5y=-1 that contains the point (1,3)
rewona [7]

Answer:

To find the equation of the line parallel to the graph, first of all find the slope of the graph by making y the subject of the formula and comparing the resulting equation with y = mx + c , knowing fully well that m stands for the slope.

So, from the equation of the graph give, y = 4x/5 +1/5, therefore the slope is 4/5. For a line to be parallel to the graph then they must have the same slope, to find the equation of the line at the given point, then we use the formula

y - y1 = m ( x - x1 )

y - 3  = 4/5 ( x - 1 )

multiply through by 5

5( y - 3 ) = 4 ( x - 1)

5y - 15 = 4x - 4

 5y - 4x = - 4 + 15

so,  5y - 4x = 11 is the equation

The volume of a cylinder is given by the formula v= m'h. where r is the radius of the cylinder and h is the height.
Verdich [7]

Answer:

The Volume of cylinder is: \mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }

Option B is correct option.

Step-by-step explanation:

We are given:

Volume of cylinder = h = 2x+7

Radius of cylinder = r = x-3

We need to find volume of cylinder

The formula used is: Volume=\pi r^2h

Putting values and finding volume

Volume=\pi r^2h\\Volume=\pi (x-3)^2(2x+7)\\Volume=\pi (x^2-6x+9)(2x+7)\\Volume=\pi (2x(x^2-6x+9)+7(x^2-6x+9))\\Volume=\pi (2x^3-12x^2+18x+7x^2-42x+63)\\Volume=\pi (2x^3-12x^2+7x^2-42x+18x+63)\\Volume=\pi (2x^3-5x^2-24x+63)\\Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi \\

So, The Volume of cylinder is: \mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }

Option B is correct option.

I WILL GIVE BRAINLIEST TO WHOEVER IS CORRECT
natali 33 [55]

Because M is the midpoint of AB, then AM and MB are equal distances. And because a segment can be written as the sum of its pieces, AM + MB = AB.

So,

AM + MB = AB                  <--- distance of a segment is the sum of its pieces

AM + AM = AB                  <--- M is the midpoint, so AM = MB

3x + 3 + 3x + 3 =  8x - 6   <--- substituting known amounts that were given

6x + 6 = 8x - 6                  <--- collect like terms on the left side

6x = 8x - 12                       <--- subtract 6 on both sides

-2x = -12                            <--- subtract 8x on both sides

x = 6                                  <--- divide both sides by -2

Because x = 6, we put it back into AM. 3(6) + 3 = 18 + 3 = 21


Thus, AM is 21 units.

I need help with these two
Strike441 [17]
#1
5x + 10 + 13x -10 = 180
18x = 180
x = 180/18
x =10

answer: value of x = 10

#2
21x +5 +37x +1 = 180
58x + 6 = 180
58x = 180 -6
58x = 174
x = 174/58
x = 3

so 37x + 1
= 37(3) + 1
=111 + 1
=112
answer: measure of the highlight angel = 112
