Answer:
A. The equation of the line parallel to line L is y = – x
B. The equation of the line perpendicular to line L is y = x
Step-by-step explanation:
We'll begin by calculating the slope of line L.
This can be obtained as follow:
y = –x + 2
Comparing the above equation with:
y = mx + c
We can see that the slope (m) = –1.
Therefore, the slope of line L is –1
A. Determination of the equation of the line parallel to line L. This is illustrated below:
When two lines are parallel, their slope (m) is equal i.e
m1 = m2
m1 = – 1
– 1 = m2
This means that the slope of the line parallel to line L is –1
Now we shall determine the equation of the line parallel to line L as follow:
Coordinate = (0, 0)
x1 coordinate = 0
y1 coordinate = 0
Slope (m) = –1
y – y1 = m(x – x1)
y – 0 = –1 (x – 0)
y = – x
Therefore, the equation of the line parallel to line L is y = – x
B. Determination of the equation of the line perpendicular to line L. This is illustrated below:
When two lines are perpendicular, the product of their slope (m) is –1 i.e
m1 • m2 = – 1
but m1 = –1
–1 x m2 = – 1
Divide both side by – 1
m2 = –1/–1
m2 = 1
Now, we shall determine the equation of the line perpendicular to line L as follow:
Coordinate = (0, 0)
x1 coordinate = 0
y1 coordinate = 0
Slope (m) = 1
y – y1 = m(x – x1)
y – 0 = 1 (x – 0)
y = x
Therefore, the equation of the line perpendicular to line L is y = x
Is √3600 rational or irrational? choose all statements are true
Answer:
Rational
Step-by-step explanation:
A surd is an irrational number. An irrational number refers to any number that can not be written in the form a/b where a and b are integers.
Given √3600, which can be written as √36 × √100 = 6 ×10 = 60.
Hence √3600 is a rational number.
Gary used candle molds, as shown below, to make candles that were perfect cylinders and spheres: What is the approximate difference in the amount of wax needed to make a candle from each of these molds? Use π = 3.14. A.) 16.75 cubic inches B.) 20.93 cubic inches C.) 24.25 cubic inches D.) 33.49 cubic inches
Answer:
A.) 16.75
Step-by-step explanation:
First, find the volume of each mold:
[tex]Cylinder_{volume}[/tex] = πr²h
Where,
π = 3.14
r = 2 in
h = 4 in
[tex]Cylinder_{volume} = 3.14*2^2*4 = 50.24 in^3[/tex]
[tex]Sphere_{volume}[/tex] = ⁴/3πr³
Where,
π = 3.14
r = 2 in
[tex]Sphere_{volume} = \frac{4}{3}*3.14*2^3 = 33.49 in^2[/tex]
Approximate difference in the amount of wax needed = 50.24 - 33.49 = 16.75 in^3

What value of x makes the equation below true?
8x – 13 = 3x + 7
O = 2
O x = 5
x = 16
O x=4
Answer:
x = 4
Step-by-step explanation:
8x – 13 = 3x + 7
add 13 to both sides
8x = 3x + 20
subract 3x from both sides
5x = 20
divide by 5 on both sides
x = 4

Max has coins worth $4.50. If the coins are all quarters, how many quarters does he have? *
Answer:
18 quarters
Step-by-step explanation:
4.50/.25=18
Answer:
He has 18 quarters
Step-by-step explanation:
Each dollar is equivalent to 4 quarters, and max has $4. Therefore max has 16 quarters. Then you add the 50 cents, which is equivalent to 2 quarters. Now you add the 16to the 2 and you get 18. Max has 18 quarters.
Which of the following correctly uses exponents to write "6 factors of 2"?
062
26
06.2
12
Please hurry!
Answer: 2^6
Step-by-step explanation:
First, when we have:
x^n
this means that we are multiplicating x by itself n times.
Now, in this case we have:
6 factors of 2 would mean that we have:
(2)*(2)*(2)*(2)*(2)*(2)
2 multiplied by itself 6 times.
This is equal to:
(2)*(2)*(2)*(2)*(2)*(2) = 2^6

What is the length of segment RS? On a coordinate plane, line R S has points (negative 4, negative 3) and (1, 9). StartRoot 65 EndRoot 12 13 StartRoot 153 EndRoot
Answer: Length of RS = 13
Step-by-step explanation: Segment is a line connecting two points.
Length or Distance of a segment is the distance between these two points and is calculated as:
[tex]d=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}[/tex]
For the line RS:
[tex]d=\sqrt{[1-(-4)]^{2}+[9-(-3)]^{2}}[/tex]
[tex]d=\sqrt{(1+4)^{2}+(9+3)^{2}}[/tex]
[tex]d=\sqrt{(5)^{2}+(12)^{2}}[/tex]
[tex]d=\sqrt{25+144}[/tex]
[tex]d=\sqrt{169}[/tex]
d = 13
The length of segment RS is 13 units.

a motor scooter travels 12 mi in the same time that a bicycle covers 5 mi. If the rate of the scooter is 2 mph more than twice the rate of the bicycle, find bith rates.
Answer:
Step-by-step explanation:
let the rate of travel of bicycle=x m/h
rate of travel of motor scooter=2x+2
time taken by motor scooter to travel 12 mi=12/(2x+2) hrs.
time taken by bicycle to travel 5 mi=5/x
as time is same
[tex]\frac{12}{2x+2}=5/x\\12x=5(2x+2)\\12x=10x+10\\12x-10x=10\\2x=10\\x=10/2=5\\rate~ of~ travel~ of~bicycle=5 m/h\\rate~ of~ travel~ of~ motor~ scooter=2x+2=2 \times 5+2=12 ~m/h[/tex]
Write an exponential function in the form y=ab^x that goes through points (0,14) and (3,3024).
Answer:
y = 14 [tex](6)^{x}[/tex]
Step-by-step explanation:
For an exponential function of the form y = a[tex]b^{x}[/tex]
Use the given points to find a and b
Using (0, 14 ), then
14 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , thus
a = 14
y = 14[tex]b^{x}[/tex]
Using (3, 3024 ) , then
3024 = 14 b³ ( divide both sides by 14 )
216 = b³ ( take the cube root of both sides )
b = [tex]\sqrt[3]{216}[/tex] = 6 , thus
y = 14 × [tex]6^{x}[/tex] ← exponential function

The diagram shows a rectangle ABCE.
D lies on EC.
DAB is a sector of a circle radius 8cm and sector angle 30º.
Calculate the area of the shaded region.
Answer:
15.25 cm²
Step-by-step explanation:
Step 1: find the width of the rectangle, AE.
[tex] cos(60) = \frac{EA}{8} [/tex]
[tex] 8*0.5 = EA [/tex]
[tex] 4 = EA [/tex]
[tex] EA = 4 cm [/tex]
Step 2: Find the area of the rectangle
[tex] Area_{rectangle} = length * width = 8*4 = 32 cm^2 [/tex]
Step 3: Find the area of the sector.
Take π as 3.14
[tex] Area_{sector} = \frac{30}{360}*3.14*8^2 [/tex]
[tex] Area_{sector} = \frac{30}{360}*3.14*8^2 = 16.75 cm^2 [/tex]
Step 4: Find the area of the shaded region.
Area of shaded region = [tex] Area_{Rectangle} - Area_{sector} = 32 - 16.75 = 15.25 cm^2 [/tex]

Find the distance between the points (3,4) and (5,9). Leave in simplest radical form.
Answer:
√29
Step-by-step explanation:
The distance between points (x1, y1) and (x2, y2) is:d = √(x2-x1)² + (y2-y1)²We have points (3,4) and (5,9), so the distance:
d = √(5-3)² + (9-4)² = √4 + 25 = √29Solve for x.
4x - 4 <8
AND 9x + 5 > 23
Answer:
2 < x < 3
Step-by-step explanation:
4x - 4 < 8 AND 9x + 5 > 23
4x < 12 AND 9x > 18
x < 3 AND x > 2 so the answer is 2 < x < 3.
Solve : 9x-28 = 0
Add 28 to both sides of the equation :
9x = 28
Divide both sides of the equation by 9:
x = 28/9 = 3.111
Write an equation fo nth term of the given arithmetic sequence 7,13,19,25,...
Answer:
The nth term for the given sequence can be written as:
[tex]a_n=6\,n+1[/tex]
Step-by-step explanation:
Notice that this arithmetic sequence is created by adding to each term a common difference of 6 units:
7 + 6 = 13
13 + 6 = 19
19 + 6 = 25
Then, using the general expression for the nth term of an arithmetic sequence of first term "[tex]a_1[/tex]" and common difference "d" we can write the nth term as:
[tex]a_n=a_1+(n-1)\,d[/tex]
which in this case translates as:
[tex]a_n=a_1+(n-1)\,d= 7\,+(n-1)\,6=7+6\,n-6=6\,n+1[/tex]
Answer:
Step-by-step explanation:
7, 13, 19, 25, .......
Arithmetic sequence.
First term = a = 7
Common difference = d = second term - first term
d = 13 - 7 = 6
nth term [tex]a_{n}=a+(n-1)d\\[/tex]
[tex]a_{n} = 7 +(n-1)*6\\\\\\a_{n}=7 + 6n - 6\\\\\\a_{n} = 1 + 6n[/tex]

Use the number line below, where RS = 7y + 2, ST = 2y +6, and RT = 13y - 12
a. What is the value of y?
b. Find RS, ST, and RT.
R
What is the value of y?
Answer: a. y=5
b. RS = 37 , ST =16 and RT = 53 .
Step-by-step explanation:
Given: On number line we have,
RS = 7y + 2, ST = 2y +6, and RT = 13y - 12.
a. Since its on number line so we have
RT = RS+ ST
i.e. 13y - 12 = (7y + 2) + ( 2y +6)
⇒ 13y - 12 = 7y + 2 + 2y +6
⇒ 13y-12 = 9y+8
⇒ 13y-9y = 8+ 12 [Subtract 9y from both sides and add 12 in both sides]
⇒ 4y = 20
⇒ y= 5 [Divide both sides by 4 ]
b. Now , RS = 7(5) + 2 = 35+2= 37,
ST = 2y +6 = 2 (5)+6 = 10+6 =16,
and RT = 13y - 12 = 13 (5)-12 = 65-12 = 53.
Hence, RS = 37 , ST =16 and RT = 53 .
Point X in quadrant III is reflected across the x-axis and then across the y-axis. In which quadrant is the image of point X?
Answer:
Quadrant I
Step-by-step explanation:
Reflection is a type of solid transformation in which an object or a point is flipped with respect to a reference point or plane to produce its image. It changes the orientation of an object, but not its shape and size.
Reflecting the point X across x-axis produces an image in quadrant II. Now, reflecting it across the y-axis would fix its image now in quadrant I.
Therefore, reflecting point X across the x-axis and then y-axis would produce its image in quadrant I.
