Linear equations are all solved the same way. Figure out the operations performed on the variable. Undo those in reverse order.

Here, the variable is
- divided by 2
- has -7 added.

In reverse order, we undo these operations by
- adding 7
- multiplying by 2.

Whatever we do to one side of an equation, we must also do to the other side. That is how the equal sign remains valid.

2 = m/2 -7
2 +7 = m/2 -7 +7 . . . . . add 7
9 = m/2 . . . . . . . . . . . . simplify
2*9 = 2*m/2 . . . . . . . . multiply by 2
18 = m . . . . . . . . . . . . . simplify. (You know that 2/2 = 1, and m*1 = m.)

The answer is m = 18.

_____
Check:
.. 2 = 18/2 -7
.. 2 = 9 -7 . . . . . . . true. The answer checks OK.

A line passes through the point (-8,9) and has a slope of 5/4.
Masteriza [31]

Answer:

The answer is

<h2>y =  \frac{5}{4} x + 19 \\</h2>

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (-8,9) and slope 5/4

The equation of the line is

y - 9 =  \frac{5}{4} (x + 8) \\  y - 9 =  \frac{5}{4} x + 10 \\ y =  \frac{5}{4} x + 10 + 9

We have the final answer as

y =  \frac{5}{4} x + 19 \\

Hope this helps you

Three vertices of a rectangle are given. Find the coordinates of the fourth vertex.
kykrilka [37]
The distance between (2,5) and (6,1) is:

\sf Distance = \sqrt{\left( 6 - 2 \right)^2 + \left( 1 - 5 \right)^2} \\\\  =\sqrt{ 16 + 16} \\  \\ = \boxed{\bf{4 \sqrt{ 2 } }}

The distance between the fourth vertex and (4,-1) should also be 4√2

The only point that gives us that distance is B. (0,3)

\sf Distance = \sqrt{\left( 4 - 0 \right)^2 + \left( -1 - 3 \right)^2} \\ \\= \sqrt{ 16 + 16} \\  \\ = \boxed{\bf{4 \sqrt{ 2 } }}

Your final answer is B. (0,3)

Sylvie bought 13 bagels and a container of cream cheese.Each bagel cost the same price.The cream cheese cost $2.95.Sylvie spent
Taya2010 [7]
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50 <u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

7.50=2.95+13(b)

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as 

4.55=13 (b)

Now, to get "b" by itself, you must divide 13 on both sides, resulting as

.35=b

This will answer your question as the cost of 1 bagel would be $0.35 per bagel.

If 2x+1/4 = 12/20 what is the value of x
ExtremeBDS [4]

Answer:

7/10 or 0.7

Step-by-step explanation:

cross multiply to get 40x+20=48

subtract 20 from both sides to get 40x=28

divide both sides by 40 to get 7/10
