Let’s remember the most basic thing in percentages, the equation.

Percent x Whole = Part.

We know the whole, and the part, but we are trying to find the percent, so we have to divide the two, first turn your whole and part into a decimal.

Percent x 0.4 = 0.18, so we divide 0.18 by 0.4

0.18/0.4 = 0.45

0.45 = 45%

<span>Simplifying 7p + 2 = 5p + 8 Reorder the terms: 2 + 7p = 5p + 8 Reorder the terms: 2 + 7p = 8 + 5p Solving 2 + 7p = 8 + 5p Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-5p' to each side of the equation. 2 + 7p + -5p = 8 + 5p + -5p</span>

Write a linear equation that passes through the two points (-6, -7) and (3, -4).
Phantasy [73]

linear equation that passes through the two points (-6, -7) and (3, -4) is y=\frac{1}{3}x-5

Step-by-step explanation:

We need to write the equation that passes through the two points (-6, -7) and (3, -4).

The equation can be written is point slope form.

The standard form of point slope equation is:

y=mx+b

where m is the slope and b is the y-intercept

Finding slope m:

Slope can be found by using formula:

slope = \frac{y_{2}-y_{1}}{x{2}-x_{1}} \\Where\,\, y_{2}=-4,y_{1}=-7,x{2}=3,x_{1}=-6\\slope =\frac{-4-(-7)}{3-(-6)}\\slope=\frac{-4+7}{3+6}\\slope=\frac{3}{9}\\slope=\frac{1}{3}

So, slope is \frac{1}{3}

Now finding y-intercept b

Putting slope \frac{1}{3} and point(-6,-7)

y=mx+b\\x=-6,y=-7,m=\frac{1}{3} \\-7=\frac{1}{3}(-6)+b\\-7=-2+b\\b=-7+2\\b=-5

So, value of b is -5

Putting values to find the equation:

y=mx+b\\m=\frac{1}{3} and b=-5\\y=\frac{1}{3}x-5

So, linear equation that passes through the two points (-6, -7) and (3, -4) is y=\frac{1}{3}x-5
