Answer:

Step-by-step explanation:

<u>Plotting </u>\underline{y=2x+3}<u />

Step 1: determine the y-intercept

(0,3)

  • plot the point as the first point on the graph

Step 2: Move 2 units up, and 1 unit left (keep repeating this process until you have reached the limit of the graph)

Step 3: Go to the other side of the graph of the first point (y-intercept)

  • move 2 units down, and 1 unit right keep repeating this process until you have reached the limit of the graph)

<em>When you've completed this process, it should look like this:</em>

Answer:

The lines blue and green are perpendicular

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope of the blue line

we have the points

(-1,-3) and (0,3)

substitute

m=\frac{3+3}{0+1}

m=\frac{6}{1}=6

step 2

Find the slope of the red line

we have the points

(3,-3) and (4,2)

substitute

m=\frac{2+3}{4-3}

m=\frac{5}{1}=5

step 3

Find the slope of the green line

we have the points

(-4,-1) and (2,-2)

substitute

m=\frac{-2+1}{2+4}

m=-\frac{1}{6}

step 4

Compare the slopes

Blue line ----> m=6

Red line ----. m=5

Green line ---> m=-\frac{1}{6}

so

The slope of the blue line and the green line are opposite reciprocal ( their product is equal to -1)

therefore

The lines blue and green are perpendicular

A sales person is given a choice of two salary plans. Plan 1 is a weekly salary of 700 plus 4% commission of sales. Plan 2 is a
bezimeni [28]

Let 's' represent the amount of sales.

Plan 1:

\text{ \$700 + (4\% of s)}\begin{gathered} \text{ \$700+(}\frac{\text{4}}{100}\times s) \\ \text{ \$700+(0.04}\times s)=\text{ \$700}+0.04s \end{gathered}

Plan 2:

12\text{ \% of s}\begin{gathered} \frac{12}{100}\times s \\ 0.12\times s=0.12s \end{gathered}

Equating the two plans together and solving for the amount of sales,

\begin{gathered} \text{Plan 2=Plan 1} \\ 0.12s=\text{ \$700+0.04s} \\  \end{gathered}

Collecting like terms,

\begin{gathered} 0.12s-0.04s=\text{ \$700} \\ 0.08s=\text{\$700} \end{gathered}

Divide both sides by 0.08,

\begin{gathered} \frac{0.08s}{0.08}=\frac{\text{ \$700}}{0.08} \\ s=\text{ \$8750} \end{gathered}

Hence, the amount of sales is $8,750.
