If slopes of the given lines are solved and observed, we get the slope of line E is [tex]m_{E}[/tex] = [tex]\frac{-5}{6}[/tex]
As per question statement, the equation for line A is [tex]y = \frac{6x}{5} - 10[/tex] Line A is parallel to line B, which is perpendicular to line C. The line D is perpendicular to line C and perpendicular to line E.
Before solving this question, we need to know about some basic formulas and concepts of equation for a line.
If Lines are parallel, their slopes are equal and if lines are perpendicular, the product of their slopes is -1.
i.e., if [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are slopes of two lines then if,
[tex]m_{1} = m_{2}[/tex] then lines are parallel
Now slope of line A can be found out by formula [tex]y=mx+c[/tex] hence slope of line A [tex]m_{A}[/tex]= [tex]\frac{6}{5}[/tex]
Line B is parallel to A so, [tex]m_{B}[/tex] = [tex]\frac{6}{5}[/tex]
Line C is perpendicular to B so [tex]m_{C} * m_{B} = -1\\m_{C} = \frac{-5}{6}[/tex]
Line D is perpendicular to C so [tex]m_{D} *m_{C} = -1\\m_{D} = \frac{6}{5}[/tex]
Line E is perpendicular to D hence [tex]m_{E} * m_{D} = -1\\m_{E} = \frac{-5}{6}[/tex]
Therefore the slope of line E is [tex]\frac{-5}{6}[/tex]

Answer:
I gotchu! The answer is 80.
Step-by-step explanation:
To find the mean, you need to add up all the scores and divide it by how many scores there are. In this case, there are 5 scores, so we can first add them all up.
70+75+80+85+90=400
Now, since there are 5 scores, you need to divide 400 by 5.
400/5=80
The mean would be 80.

Eva left her house at time zero and drove to the store, which is 3 blocks away, at a
speed of 1 block per minute. Then she stopped and went into the store for 3 minutes.
From there, she drove in the same direction at a speed of 1 block every 2 minutes
until she got to the bank, which is 3 blocks away from the store. She stopped at the
bank for 6 minutes. Then she drove home at a speed of 1 block every minute. Make a
graph of showing the number of blocks away from home that Eva is a minutes after
she leaves her house, until she gets back home.
The function f(x), representing the number of blocks Eva is away from her house after x minutes is
[tex]f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}[/tex]
The graph for the same is attached.
In the question, we are asked to form a graph showing the number of blocks, that Eva is away from her home at x minutes, after she leaves her home.
To form the graph, we first try to make a function for x minutes, f(x), showing the number of blocks Eva is away from her home after x minutes.
Since x represents time, it cannot be negative.
At x = 0, f(x) = 0, as she is at her home at 0 minutes.
Then, Eva visits the store, 3 blocks away from her home at a speed of 1 block per minute.
Thus, she moves 1 block every minute up to 3 minutes.
Thus, we get f(x) = x, 0 < x ≤ 3.
After this, she spends 3 minutes at the store, giving f(x) = 3, 3 < x ≤ 6.
Then she moves towards the bank, in the same direction, 3 blocks away at the speed of 1 block every 2 minutes.
Thus, in every minute, she travels 1/2 block.
Thus, the function can be designed as follows:
f(x) = 3 + (1/2)(x - 6), 6 < x ≤ 12,
or, f(x) = x/2, 6 < x ≤ 12.
Now, we are given that she stops at the bank for 6 minutes.
Thus, we get, f(x) = 6, 12 < x ≤ 18.
Now, she drove back home, at the speed of one block every minute.
Thus, we get f(x) = 6 - (x - 18), 18 < x ≤ 24,
or, f(x) = 24 - x, 18 < x ≤ 24.
At the 24th minute, Eva reaches her house back, giving f(x) = 0, x > 24.
Thus, the complete function can be shown as:
[tex]f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}[/tex]

two and half of a number added to three quarters of the same number gives you 13.find the number.
Answer:
52/21
Step-by-step explanation:
Translate the word equation into an algebraic equation as follows:
Let the number be X
two-and-a-half of a number --> (2 1/2) X
2 1/2 = (2 x 2 + 1) = 5/2
So two-and-a-half of a number --> (9/2)X = 9X/2
three-quarters of the same number --> (3/4)X --> 3X/4
two and half of a number added to three quarters of the same number becomes 9X/2 + 3X/4
gives you 13 --> = 13
So we get the equation:
9X/2 + 3X/4 = 13
Multiply both sides by 4 to get rid of the denominators
4.(9X/2) + 4(3X/4) = 4 x 13 = 52
36X/2 + 12X/4 = 52
==> 18X + 3X = 52
==> 21X = 52
==> X = 52/21

Find the dimensions of a rectangle if the perimeter is 318 inches and the
length is half the width plus nine inches.
The dimensions of the rectangle are 59 by 50 inches
How to fnd the dimensions of a rectangle?The given parameters are
Length (l) = 1/2 width (w) + 9
Perimeter (P) = 318
Perimeter is calculated as
P = 2 (l + w)
Substitute l = 1/2w + 9 in P = 2(l + w)
So, we have
2 * (1/2w + w + 9) = 318
Evaluate the like terms
2 * (1.5w + 9) = 318
Divide by 2
1.5w + 9 = 159
So, we have
1.5w = 150
Divide by 15
w = 100
Substitute w = 100 in l = 1/2w + 9
l = 1/2 * 100 + 9
Evaluate
l = 59
Hence. the dimensions of the rectangle are 59 by 50 inches

A quantity increases from 225 to 250. what is the percentage increase? round your answer to the nearest tenth of a percent.
The percentage increase for given quantity is 11.1%
In this question,
A quantity increases from 225 to 250.
So, the absolute change in the quantity would be,
|225 - 250| = 25
The relative increase of the quantity would be,
R = [tex]\frac{|225 - 250|}{225}[/tex]
R = 25 / 225
R = 0.111
We know that, the percentage increase of the quantity is the relative increase multiplied by 100.
So, the percentage increase of given quantity would be,
P = 0.111 × 100
P = 11.1%

an isosceles trapezoid has legs of length 30 cm each, two diagonals of length 40 cm each and the longer base is 50 cm. what is the trapezoid’s area?
768 cm'^2 is the trapezoid’s area.
What is isosceles trapezoid?
Isosceles trapezoids have equal length non-parallel sides, hence the name "isosceles" which means "equal legs". The "legs" are another name for these equal sides.
Let 50 cm = the bottom base
We can find the area of one of the triangles that comprise the area of the trapezoid.....its sides are 30, 40 and 50 cm
Let s be the semi-perimeter of one of the triangle = [ 50 + 40 + 30 ] / 2 = 60 cm
And the area of of this triangle = sqrt [ s ( s - a) (s - b) ( s -c) ] where a,b, c are the sides
So...we have sqrt [ 60 ( 60 - 30) (60 - 40) (60 - 50) ] = sqrt [ 60 * 30 * 20 * 10 ] =
sqrt [ 1800 * 200] = sqrt [ 3600 * 100] = 60 * 10 = 600 cm ^2
Now the base of this triangle = 50 and the height can be found as
follows :
Area = (1/2) 50 * height
600 = 25 * height
height = 24 cm and this is the height of the trapezoid
Now....the top base can be found as 50 - 2 sqrt [ 30^2 - 24^2 ] = 14 cm
So....the area of the trapezoid = (1/2) height ( sum of the bases) = (1/2) (24) ( 50 + 14) = 12 ( 64) = 768 cm'^2

Find the amount of money that the bank loaned out at 7.9%.
The amount that the bank loaned out at 7.9% is $1,574.00
How do represent the amounts lent at different rates?
On the assumption that x amount was loaned at 7.9% and that the remaining amount, (8,200-x) was loan out at 7.4%, we can determine the interest charged on each loan as the loan multiplied by the interest rate
interest on 7.9% loan=7.9%*x=0.079x
interest on 7.4% loan=7.4%*(8200-x)
interest on 7.4% loan=606.80-0.074x
total interest=0.079x+606.80-0.074x
total interest=0.005x+606.80
