Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.

Let x = width and x+10 = length

So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.

Thus the area is 5⋅15=75m2

Write the equation of the given line in slope intercept form (2,3) (8,6)
Dominik [7]

Answer:

y = 1/2x + 2

Step-by-step explanation:

slope:

6 - 3 / 8 - 2 = 3 / 6 = 1/2

start by putting it in point slope form and then simplify it to slope intercept form:

y - 3 = 1/2(x - 2)

y - 3 = 1/2x - 1

y = 1/2x + 2

Solve the system of equations using substitution or elimination. Show all work for credit.
Tomtit [17]
Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
y =  \frac{ -  \frac{1}{2} x + 2}{3}  \\ y =  - x + 9

Since both expressions are equal to y, you have to equal both expressions like this:
\frac{  - \frac{ 1}{2}x + 2 }{3}  =  - x + 9
Now you can solve the equation:
-  \frac{1}{2} x + 2 = 3( - x + 9) \\   - \frac{ 1}{2}x  + 2 =  - 3x + 27 \\  \\  -  \frac{1}{2} x + 3x = 27 - 2 \\   \frac{5}{2} x = 25 \\ x =  \frac{(25)(2)}{5}  \\ x = 10
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result

y =  - (10) + 9 \\ y =  - 1
So, the answer is x=10 and y=-1

Explain how to find the middle quartile of a box-and-whisker plot.
Soloha48 [4]

Step-by-step explanation: The middle quartile or <em>second quartile</em> as I like to call it is the median of the entire data set. Remember that the median is the middle number when the data is written from least to greatest.
