The length of a rectangle is three times the width. The perimeter of the rectangle is 40 inches. What is the area of the rectang

Marizza181 [45]

Answer: 75 square

Explanation:

Width is X

Length is 3x

Every rectangle has 2 equal widths x 2 equal lengths

Perimeter is 2x + 2(3x) = 40
X = 5

Width is now 5in

Length is now 15in

Area is 75in^2

Half of a perimeter is length + width, which equals to 20in

4x = 20, CX = 5
= 75 sq

Given the following 2 equations, state whether these equations are parallel, perpendicular, or neither.

stiks02 [169]

Answer:

Neither

Explanation:

The slope-intercept form of the equation of a line is generally given as;

$y=mx+b$

where m = the slope of the line

b = the y-intercept of the line

Two lines are said to be parallel if they have the same slope. Looking at the two given equations below, we see that the slope of the 1st one, 5/7, is different from the slope of the 2nd one, 7/5;

$\begin{gathered} y=\frac{5}{7}x+14 \\ y=\frac{7}{5}x-20 \end{gathered}$

Two lines are said to be perpendicular if their slopes are negative reciprocals of each other, let's go ahead and compare their slopes;

$\begin{gathered} m_1=\frac{5}{7} \\ m_2=\frac{7}{5} \\ \therefore m_2=\frac{1}{m_1_{}} \end{gathered}$

So the two lines are not perpendicular to each other. It, therefore, means that the correct answer will be Neither.

Write the points (-3,5) and (1,1) in slope-intercept form

Jobisdone [24]

Y=mx+b
m=slope
b=yint

find slope
slope between (x1,y1) and (x2,y2) is (y1-y2)/(x1-x2)

given
(-3,5) and (1,1)
slope=(5-1)/(-3-1)=4/-4=-1

y=-1x+b
find b
when x=1, then y=1
1=-1(1)+b
1=-1+b
add 1
2=b

y=-x+2
