Answer:
x= 40
so
3x-5= 115
2x-15= 65
Step-by-step explanation:
C is the correct answer. I see that you put a mark on that choice so you are right if you thought that. I hope this helps!
Answer:
C
Step-by-step explanation:
The 2 angles are same- side interior angles and are supplementary, thus
3x - 5 + 2x - 15 = 180, that is
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40
Thus
3x - 5 = 3(40) - 5 = 120 - 5 = 115°
2x - 15 = 2(40) - 15 = 80 - 15 = 65°
A reflection of shape I across the y-axis, followed by a (90 counterclockwise rotation 90 clockwise rotation 180 rotation) and then a translation left 6 units and down 4 units confirms congruence between shape I and shape II. Alternatively, a (90 counterclockwise rotation 90 clockwise rotation 180 rotation)
of shape II about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape II and shape I.
Answer:
1 90 clockwise rotation 2 90 counterclockwise rotation
Step-by-step explanation:
Transformation is a method required to resize or change the orientation of a given shape or figure. The required answer is:
i. Statements b and d would map Shape l onto Shape II
ii. Statements a, c, e, and f does not map Shape l onto Shape II
What is transformation?Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation. The translation is a method that requires moving every point in a given shape in the same direction and same unit.
Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased. Thus the answers to the question are listed as follows:
a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 6 units. Does not Map Shape l onto Shape II
b. a 90° clockwise rotation about the origin and then a translation left 6 units Answer: Maps Shape l onto Shape II
c. a 90° counterclockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation left 6 units.
d. Does not Map Shape l onto Shape IId. a 90° clockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation right 4 units Answer: Maps Shape l onto Shape II
e. a 180° rotation about the origin, followed by a reflection across the y-axis, and then a 90° clockwise rotation about the answer of the origin: Does not Map Shape l onto Shape II
f. a reflection across the y-axis, followed by a 90° counterclockwise rotation about the origin, and then a translation right 4 units. Does not Map Shape l onto Shape II.

On January 3rd, the Earth is 147,500,000 kilometers away from the Sun. On July 4th, the Earth is 152,500,000 kilometers away from the Sun. The Sun has a radius of about 865,000 kilometers.
Could the Earth's orbit be a circle with some point in the Sun as its center? Explain your reasoning.
Answer:
No
Step-by-step explanation:
It could not because in order for it to be a circle the number of kilometers would have to be constant, however in earth's orbit it is not constant, therefore it is an oval, not a circle.
Which city is closest to sea level?
Answer:
City A
Step-by-step explanation:
I mean B C and D are all about 0.5 or -0.5 while B is 1 3/4

AGIAN HELP!!!!Identify the point on the vertical axis (y-axis) and state the real-world meaning of that point.
Answer:
The point on the vertical axis (y-axis) represents the y-intercept.
It represents the height over the sea level at the starting point of hiking
Step-by-step explanation:
From the graph
The y-axis represents the height above the sea level in feetThe x-axis represents the hours hiking→ The point on the vertical axis (y-axis) represents
The initial height above the sea levelThis point is the starting point of hikingIt called the y-intercept (0, 2000)→ Which means it represents their height at 0 hour
→ The real-world meaning of that point is:
They are 2000 feet above the sea level when they decided to start hikingThe point on the vertical axis (y-axis) represents the y-intercept.
It represents the height over the sea level at the starting point of hiking

f(x) = x2+9
g(x) = X-9
Find f(x)*g(x).
Answer:
f(x)g(x) = x³ - 9x² + 9x - 81
General Formulas and Concepts:
Distributions - Expanding with FOIL (First, Outside, Inside, Last)
Step-by-step explanation:
Step 1: Define
f(x) = x² + 9
g(x) = x - 9
Find f(x) · g(x)
Step 2: Find
Set up expression: f(x)g(x) = (x² + 9)(x - 9)Expand (FOIL): f(x)g(x) = x³ - 9x² + 9x - 81A and B are supplementary angles. If m A=(x-18)° and mB =(x-20),
find the measure of B
Answer:
89 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so we can add up A and B and make it equal to 180.
(x-18)+(x-20)=180
2x-38=180
2x=218
x=109
then, we plug in 109 for x in the mB equation.
mB=x-20
mB=109-20
mB=89 degrees
therefore, the measure of B is 89 degrees.
Answer:
B = 89
Step-by-step explanation:
Supplementary angles: A + B = 180
Simplify: x-18 +x -20 = 180
2x-38 = 180
2x = 218
x= 109
B = x-20
B = 89

a) 5x/2+ 1 = 11
b) 2x/7 – 3 = 2
Answer:
A) x=4
B) x=35/2
Step-by-step explanation:
calculate the product
A) 5x/2+1=11
multiply both sides of the equation by 2
5x+2=22
move the constant to the right hand side and change its sign
5x+22-2
now subtract the numbers
5x=20
now didvide both sides
5x=20
x=4
B)
calculate the product
2x/7-3=2
multiply both sides of the equation by 7
2x-21=14
move the constant to the right hand side and change its sign
2x=14+21
add the numbers
2x=35
now divide both sides of the equation by 2
x=35/2

Jezebel is planning a party at the skating rink. The cost for each person attending is $3.50 for skate rental and $5.00 for food. Jezebel cannot spend more than $300. Which inequality could be used to find the greatest number of people, p, that can attend?
Answer:
The inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.
Step-by-step explanation:
From the information provided, you can write an inequality where total cost for people attending at the party should be less than or equal to $300:
3.50p+5.00p≤300
8.50p≤300
Now, you can solve for p:
p≤300/8.50
p≤35
According to this, the answer is that the inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

The volume of a rectangular pool is the product of the pool's area and depth. Suppose a pool that is 12 feet deep has
a volume of 10368 ft? What is the area of the pool?
The area of the pool is
square feet.
The area of the pool is the product of the pool's length and width. Suppose the pool's length is 24 ft. What is the
pool's width?
The pool's width is
feet
Answer:
The area of the pool is [tex]864\ ft^2[/tex]
The pool's width is 36 ft
Step-by-step explanation:
Volume and Area
The volume of a rectangular pool is the product of the pool's area and depth. We are given the pool's depth d=12 feet and the pool's volume V=10368 [tex]ft^3[/tex]
Since:
[tex]V= d*A[/tex]
Solving for A:
[tex]\displaystyle A=\frac{V}{d}=\frac{10368}{12}=864\ ft^2[/tex]
The area of the pool is [tex]864\ ft^2[/tex]
Now we calculate the pool's width, knowing the area is the product of the pool's length and width. Knowing the length is L=24 ft:
[tex]A=L*W[/tex]
Solve for W:
[tex]\displaystyle W=\frac{A}{L}=\frac{864}{24}=36[/tex]
The pool's width is 36 ft
Ojos del Salado is the highest mountain in Chile, with a peak at about 6900 meters above sea level. The Atacama Trench, just off the coast of Peru and Chile, is about 8100 meters below sea level (at its lowest point).
a. What is the difference in elevations between Mount Ojos del Salado and the Atacama Trench?
b. Is the elevation halfway between the peak of Mount Ojos del Salado and the Atacama Trench above sea level or below sea level?
Explain without calculating the exact value. c. What elevation is halfway between the peak of Mount Ojos del Salado and the Atacama Trench?
A) add the two elevations together:
6900 + 8100 = 15,000 meters.
B) Divide the total distance by 2:
15,000 / 2 = 7,500 meters.
Because the distance to the halfway point is larger than the elevation of Ojos del Salado, the elevation would be below seal level.
C Add the halfway point from part B to the lowest elevation:
-8100 + 7500 = -600 meters
