To add or subtract fractions, you need to find the smallest shared multiple to use as your denominator (the number on the bottom). This is called the least common denominator. You then have to multiply each entire fraction (top and bottom) so that both of your fractions have the same denominator. Then you add/subtract the numerators ONLY and leave the denominator.

HELP?? If one is added to a number and the sum is tripled the result is 19 more then the number. Find the number. Um?

Viefleur [7K]

<h3>The value of x is equal to 8.</h3>

3(x + 1) = 19 + x

Distributive property.

3x + 3 = 19 + x

Subtract x from both sides.

2x + 3 = 19

Subtract 3 from both sides.

2x = 16

Divide both sides by 2.

x = 8

Write the slope-intercept form of the equation of the line with the given characteristics. Perpendicular to y = -5x + 2 and pass

natka813 [3]

The slope intercept form of a line can be expressed as,

$y=mx+c$

Here, m is the slope of the line and c is the y intercept.

Comparing the above equation with the given equation of a line y=-5x+2, we get

m=-5.

The slope of a line perpendicular to line with slope m is -1/m.

Hence, the slope of line perpendicular to y=-5x+2 is,

$m_1=\frac{-1}{m}=\frac{-1}{-5}=\frac{1}{5}$

The new line is given to be passing through point with coordinates (x1, y1)=(3, -1).

The point slope form of a line passing through point with coordinates (x1, y1)=(3, -1) and having slope m1 is,

$\begin{gathered} y-y_1=m_1(x-x_1) \\ y-(-1)=\frac{1}{5}(x-3) \\ y+1=\frac{1}{5}x-\frac{3}{5} \\ y=\frac{1}{5}x-\frac{3}{5}-1 \\ y=\frac{1}{5}x-\frac{3-5}{5} \\ y=\frac{1}{5}x-\frac{8}{5} \end{gathered}$

Therefore, the slope-intercept form of the equation of the line perpendicular to y = -5x + 2 and passing through (3,-1) is,

$y=\frac{1}{5}x-\frac{8}{5}$

What is the perimeter of the parallelogram? 18 m 24 m 36 m

Mamont248 [21]

Answer:

36m

Step-by-step explanation:

The perimeter is given by

P = 2(l+w)

The length is 12 and the width is 6

P = 2(12+6)

P = 2(18)

P = 36

Time is usually expressed on the vertical or horizontal axis of a line graph.

vekshin1

Answer:

Horizontal axis

Step-by-step explanation:

we know that

In a line graph, vertical axis usually represented the dependent variable and horizontal axis usually represented the independent variable. The time is usually represented in the horizontal axis because is a independent variable
