Answer:

  dependent

Step-by-step explanation:

The percentage of males depends on whether they attend the concert. The events are dependent.

If the events were independent, the percentage would remain the same regardless of concert attendance.

4x +40 = 80 <br> Step by step how to solve?
oksano4ka [1.4K]

Answer:

<u>x=10</u>

Let's solve your equation step-by-step:

4x+40=80

<em>Step 1: Subtract 40 from both sides</em>

4x+40−40=80−40

4x=40

<em>Step 2: Divide both sides by 4</em>

4x/4=40/4

Answer:

<u>x=10</u>

Graph the solution to the following linear inequality in the coordinate plane 5x-y&gt;-3
Irina18 [472]

Answer:

Here's one way to do it

Step-by-step explanation:

1. Solve the inequality for y

5x - y > -3

      -y > -5x  -  3

       y < 5x + 3

2. Plot a few points for the "y =" line

I chose

\begin{array}{rr}\mathbf{x} & \mathbf{y} \\-2 & -7 \\-1 & -2 \\0 & 3 \\1 & 8 \\2 & 13 \\\end{array}

You should get a graph like Fig 1.

3. Draw a straight line through the points

Make it a dashed line because the inequality is "<",  to show that points on the line do not satisfy the inequality.

See Fig. 2.

4. Test a point to see if it satisfies the inequality

I like to use the origin,(0,0), for easy calculating.

y < 5x + 3

0 < 0 + 3

0 < 3. TRUE.

The condition is TRUE.

Shade the side of the line that contains the point (the bottom side).

And you're done (See Fig. 3).

the slope of the line below is -3. use the coordinates of the labeled point to find a slope-point equation of the line. (5,-7)
HACTEHA [7]

\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{-7})~\hspace{10em} slope = m\implies -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-7)=-3(x-5) \\\\\\ y+7=-3x+15\implies y=-3x+8
