<u><em>These are the steps:</em></u>

|3x|=3x Convert the 3x to positive

x=6 Divide 3 to both sides

<u><em>Answer</em></u>: x=6

We can get two different equations from this:

3x = 18

and

3x = -18

So:

x = 6, x = -6

x = {6, -6}

P is a rectangle with a length 40 cm and width x cm

Vesnalui [34]

We know that
<span>the length of Q is 25% more than the length of p
</span>so
length Q=1.25*40--------> 50 cm

<span>the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18

the answer is
the ratio </span><span>x:y is
</span><span>25:18</span>

Because of her work schedule, Molly Kay plans to take classes at 8:00, 10:00, and 11:00. Five courses that fit her program are o

pychu [463]

Answer: There are 90 different schedules are possible for Molly Kay.

Step-by-step explanation:

Since we have given that

Three time scheduled at 8:00, 10:00, 11:00.

Number of courses offer at 8:00 = 5

Number of courses offer at 10:00 = 9

Number of courses offer at 11:00 = 2

So, the number of different schedules are possible for Molly Kay is given by

$^{5}C_1\times ^9C_1\times ^2C_1\\\\=5\times 9\times 2\\\\=45\times 2\\\\=90$

Hence, there are 90 different schedules are possible for Molly Kay.

I don’t understand how to solve this graph.<br> (Y=MX+B)

Alla [95]

Answer:

The equation of line shown in the graph is $\mathbf{y=-\frac{1}{2}x -1}$

Step-by-step explanation:

We need to find equation of the line shown in graph.

The equation of line will be in slope-intercept form $y=mx+b$ where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding y-intercept

Looking at the graph, we can find y-intercept when x =0, the value of y is known as y-intercept.

So, when x =0, y=-1

So, y-intercept is -1

Finding Slope

Now, for finding slope, consider 2 points on graph

(0,-1) and (-2,0)

Slope can be found using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have $x_1=0, y_1=-1, x_2=-2, y_2=0$

Putting values and finding slope:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-1)}{-2-0} \\Slope=\frac{0+1}{-2-0} \\Slope=\frac{1}{-2} \\Slope=-\frac{1}{2}$

So, slope is $m=-\frac{1}{2}$

Equation of line

Now, equation of line having slope $m=-\frac{1}{2}$ and y-intercept b = -1 is

$y=mx+b\\y=-\frac{1}{2}x -1$

So, equation of line shown in the graph is $\mathbf{y=-\frac{1}{2}x -1}$
