<span>you have 2 points (0,20) and (10,100) now find the slope using change in y divided by change in x
m=(100-20)/(10-0)
m=80/10
m=8 is the slope</span>

If we plot the given values in the Cartesian plane, the points to which the line would pass are (0, 20) and (10, 100). Thus, the slope m is,
                        m = (y2 - y1) / (x2 - x1)
Substituting,
                         m = (100 - 20) / (10 - 0) = 8
Thus, I saved 8 pesos per week. The answer to the question is letter C.

If you use the addition property of equality , what number would you add to both sides of the equal sign to isolate the variable
kkurt [141]

Answer:

The answer is "\frac{26}{7}"

Step-by-step explanation:

The whole question can be found in the file attached.

\to x + \frac{5}{7} = \frac{31}{7}\\\\

Subtracting the \frac{5}{7} from both sides of the equations:

\to x +\frac{5}{7}  - \frac{5}{7}  = \frac{31}{7}  - \frac{5}{7} \\\\

                    = \frac{31-5}{7} \\\\= \frac{26}{7} \\\\

There is a bag filled with 4 blue, 3 red and 5 green marbles.
bearhunter [10]

Answer:

1/11

Step-by-step explanation

There are 12 marbles in the bag. When we first pick we have 4 blue marbles. So 4 blue marbles/12 random marbles. When we pick blue and noted, there are 3 marbles in the bag because of we didn't put it back. So when we choose again there are 11 marbles and 3 blue marbles in the bag. Choosing a blue one case is 3/11.

The last part of this case is happening as a chain. So we need to multiply our two answers.

=4/12*3/11

=1/3*3/11

=1/11

What is the solution of the system equations y =-3x +8 y = -5x -2
Talja [164]

Answer:

Since both equations are equal to y, we can set them equal to each other.

y =-3x +8

y = -5x -2

-3x +8 = -5x -2

Solve for x.To do this, we need to get x by itself. First, move all the numbers to one side of the equation, and all the variables to the other.

-3x +8 = -5x -2

Add 5x to both sides

-3x+5x +8=-5x+5x -2

2x+8=-2

Subtract 8 from both sides

2x+8-8 = -2-8

2x=-10

Now, all the numbers are on one side, with the variables on the other. x is not by itself, it is being multiplied by 2. To undo this, divide both sides by 2

2x/2= -10/2

x= -5

Now, to find y, substitute -5 in for x in one of the equations.

y = -5x -2

y= -5(-5) -2

y=25-2

y=23

Put the solution into (x,y)

<u><em>The solution is (-5, 23)</em></u>

Solve each inequality. The variable should be on the left-hand side in your solution.
lara [203]

Answer:

x≤  −96 /23

Step 1: Simplify both sides of the inequality.

Step 2: Subtract 1/8x from both sides.

Step 3: Subtract 12 from both sides.

Step 4: Multiply both sides by 8/23.
