Help please ASAP 10 points
Answer:
The answer is D
Step-by-step explanation:
Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary
This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.
You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other
Hope this helped you!!!

Betsy buys three lamps and two end tables and pays $520. Her friend Tina buys two lamps
and RETURNS an end table and only pays $20. What do the lamps and end tables cost?
9514 1404 393
Answer:
lamp: $80end table: $140Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.
One number is four more than a second number. Two times the first number is 8 more than four times the second number.
Answer:
The required numbers are:
First number = 4
Second number = 0
Step-by-step explanation:
Let First number = x
second number = y
We are given:
One number is four more than a second number.
Writing in mathematical form:
[tex]x=y+4[/tex]
Two times the first number is 8 more than four times the second
Writing in mathematical form:
[tex]2x=4y+8[/tex]
Now, we will solve these equations by substitution to find values of x and y
Let:
[tex]x=y+4--eq(1)\\2x=4y+8--eq(2)[/tex]
Now, putting value of x from eq(1) into eq(2)
[tex]2x=4y+8\\Put\:x= y+4\\2(y+4)=4y+8\\2y+8=4y+8\\2y-4y=8-8\\-2y=0\\y=0[/tex]
So, we get y=0
Now put value of y in equation 1 to get value of x
[tex]x=y+4\\x=0+4\\x=4[/tex]
So, we get x=4
So, the required numbers are:
First number = 4
Second number = 0

Is it a right triangle?
Answer:
No, it is a obtuse triangle instead
Step-by-step explanation:
So, you use pythagorean and theorem which is a^2 + b^2 = c^2
So when you plugin in the numbers, it's 20^2__ 12^2 + 12^2
When you square them you get left with 400__144 + 144
Then, you add 144 + 144 = 288
But since 400 is > than 288, then it's an obtuse triangle.
Answer:
No
Step-by-step explanation:
It does not follow the Pythagorean Theorem, which states that the two shorter sides squared (squared BEFORE added together). 12 squared is 144, and 144 plus 144 equals 288. 20, which seems to be the hypotenuse, squared is 400. 288 does not equal 400.
We want to find the zeros of this polynomial:
p(2) = (2x - 1)(x+3)(x + 1)(x - 2)
Plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answer:
How do you find the zeros of a polynomial graphically?
Step-by-step explanation:
If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. The zeros of a polynomial can be found by finding where the graph of the polynomial crosses or touches the x-axis.

Answer:
C = 4x+ 16
Step-by-step explanation:
We know that When two parallel lines are cut by a third line, the third line is called the transversal, forming 8 angles.
From the attached diagram,
∠E and (2x+8) are vertical angles formed by the transversal line.
We know that vertical angles are equal.
Hence,
∠E = (2x+8)
∠A and ∠E are called the corresponding girls.
as
∠E = (2x+8)
so
∠A = ∠E = (2x+8)
Therefore,
C = m∠A + m∠E
C = 2x+8 + 2x+8
C = 4x+ 16
Therefore,
C = 4x+ 16

Solve the following system of equations with any method. Show all work and explain your thinking for each
step in the process.
2x- 10y = 10
Sx+9y =9
Answer: Let's solve for x.
2x−10y=10
Step 1: Add 10y to both sides.
2x−10y+10y=10+10y
2x=10y+10
Step 2: Divide both sides by 2.
2x

sx+9y+−9y=9+−9y
sx=−9y+9

at 5 p.m., the temperature began dropping 3 f every hour for 6hrs. what was the temperature after 6hrs?
time temperature
3 p.m. 14
5 p.m. 11
Answer:
-7°
Step-by-step explanation:
every hour the temperature dropped 3° so in 6 hours it would be -7° because 3x6 is 18 and 11-18 is -7
Determine all values of k that make each of the following a perfect square trinomial. X^2+8x+k
Answer:
k can either be
12
or
−
12
.
Step-by-step explanation:
Consider the equation
0=x2+4x+4
. We can solve this by factoring as a perfect square trinomial, so
0=(x+2)2→x=−2 and−2
. Hence, there will be two identical solutions.
The discriminant of the quadratic equation (b2−4ac) can be used to determine the number and the type of solutions. Since a quadratic equations roots are in fact its x intercepts, and a perfect square trinomial will have
2 equal, or 1
distinct solution, the vertex lies on the x axis. We can set the discriminant to 0 and solve:
k2−(4×1×36)=0
k2−144=0
(k+12)(k−12)=0
k=±12
Which number is less than 5.17 and greater than 5.04.
there can be infinitely many solutions
For example: 5.16 and 5.06
Two of the vertices of a rectangle are (6,1) and (7,1) . IF the rectangle has a perimeter of 18 units, then what are the coordinates of its other two vertices
Answer:
(6 , -9) (7, -9)
Or
(6, 11) (7, 11)
Step-by-step explanation:
Given: Two of the vertices of a rectangle are (6,1) and (7,1)
Perimeter= 18 units
To get the value of "x"
The distance between Two point can be calculated as (6-7)=-1
Then x= -1
We can get the value of "y" by using expression for perimeter,
The perimeter P= 2x+2y=18
= 2(-1)+2y= 18
-2+2y=18
2y=18+2
2y= 20
y=10
The "y" coordinate can move up or can move down
y1=( 1-10)=-9
Or
y2=( 1+10)=11
Hence, the two other points are;
(6 , -9) (7, -9)
Or
(6, 11) (7, 11)

Step-by-step explanation:
It takes Zion three times as long to paint a room as it does Sanjay. How long does it take each person by
himself if they can paint the room together in 30 minutes?
Answer:
It takes Sanjay 40 minutes and Zion 120 minutes
Step-by-step explanation:
If it takes Sanjay x minutes, it takes Sanjay 3 * x = 3x minutes
Painting together, they spent 30 minutes
1/x + 1/3x = 1/30
4/3x = 1/30
4 * 30 = 3x * 1
120 = 3x
x = 120/3
x = 40 minutes
3x = 3 * 40 = 120 minutes

Sam is interested in buying a TV. At Walmart, the TV is regularly prices at $599.99 and is on sale for 20% off the regular price. At Best Buy, the same TV is regularly prices at $899.99 and is on sale for 30%off the regular price.
What is the difference in the sale price of the TV between these two stores?
Show your work.
Answer:
If 30% of 599.99 is 197.99 and 30% of 899.99 is 269.99 then you subtract 269.99-197.99= $72
