Which relationships describe angles 1 and 2? Select each correct answer.
Adjacent angles
Vertical angles
Complementary angles
Supplementary angles
Answer:
They are adjacent angles and supplementary angles.
Step-by-step explanation:
∠1 and ∠2 are supplementary angles because they form a linear pair who sum = 180°
∠1 and ∠2 are adjacent angle because they are next to each other or you can say that they share a common side and have the same vertex.

→ 12x - 6
therefore, option A is correct.
hope this answer helps you dear!
The required simplified solution of the given expression is 12x -6. Option A is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
= 4 + 5(3x -2) - 3x
Following the distributive property,
= 4 + 15x - 10 - 3x
Following the associative property,
= 4 - 10 + 15x - 3x
= -6 + 12x
= 12x - 6
Thus, the required simplified solution of the given expression is 12x -6. Option A is correct.

Find the equation of this line plz help
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]
The line crosses the y- axis at (0, 1 ) ⇒ c = 1

3) I get a 15% employee discount, but then have to pay 8.2% tax on the discounted price. What do I pay for a $300
item?
Answer:
$243.45
Step-by-step explanation:
300 * 0.15 = 45
300 - 45 = $225
$225 is the discounted price
225 * 0.082 = 18.45
225 + 18.45 = $243.45

As long as that a football team charges $ 30 per ticket and averages 20,000 people per game, and each person spend an average of $ 8 on concessions, and for every drop of $ 1 in price, the attendance rises by 800 people, to determine what ticket price should the team charge to maximize total revenue, the following calculation must be performed:
20,000 x 30 + 20,000 x 8 = 760,000 24,000 x 25 + 24,000 x 8 = 792,00024,800 x 24 + 24,600 x 8 = 792,00025,600 x 23 + 25,600 x 8 = 793,600 26,400 x 22 + 26,400 x 8 = 792,000

Constructed Response
Two skyscrapers are under construction in Atlanta. They will sit on opposite sides of Peachtree St. and
the architect has designed them to be similar. The architect made a sketch of two rectangles to model
the front view of the two buildings and included the following statement: ABCD ~ JKLM. It was also given
that AB = 1600 ft., BC = 200 ft., and JM = 150 ft.. Use the scenario to solve problems (a) through (d)
a.) Which rectangle is being used to model the taller building?
b.) Which line segments could be used to model the height of the smaller building?
c.) What is the height of the taller building? Explain your reasoning.
d.) What is the height of the smaller building? Explain your reasoning.
e.) Would it make sense to say that the scale factor from smaller building to taller building is 3/4?
Explain your reasoning.
A rectangle is a quadrilateral which has the length of its opposite sides to be equal. Thus, the following are the solutions to the questions:
a) The rectangle used to model the taller building is ABCD.
b) The line segment used to model the height of the smaller building is JM = KL.
c) The height of the taller building is 200 feet.
d) The height of the smaller building is 150 feet.
e) Yes, the scale factor from small to tall building is [tex]\frac{3}{4}[/tex].
Rectangles have equal length of opposite sides , and the sum of its interior angles to be [tex]360^{o}[/tex]. Since the two given skyscrapers were modeled with respect to rectangles ABCD and JKLM, then the answers to the questions are:
a) The rectangle used to model the taller building is ABCD. Since the length of a rectangle is always greater than its width. So that the height; AD = BC.
b) The line segment that can be used to model the height of the smaller building is; JM = KL. This represent the width of the rectangular model for the small building.
c) The height of the taller building is AD = BC = 200 feet. The width of a rectangle is often smaller than its length, which in this case is the height.
d) The height of the smaller building is JM = KL = 150 feet. The length of a rectangle is usually longer than its width.
e) Yes, it would make sense because:
scale factor = [tex]\frac{height of the smaller building}{height of the taller building}[/tex]
= [tex]\frac{150 ft}{200ft}[/tex]
= [tex]\frac{15}{20}[/tex]
scale factor = [tex]\frac{3}{4}[/tex]

Question 5 of 10
The graph shows the function f(x) = 2^x.
What is the value of x when f(x) = 4?
Answer:
A. 2
Step-by-step explanation:
Our y-axis is equivalent to f(x), so we can use it to find the value of x when f(x) = 4. If we look at the graph, we can find that an f(x) value of 4 (or, a y-value of 4) has an x-value of 2.
We could also figure this out by making f(x) equal to 4 in the equation:
[tex]4=2^{x}[/tex]
2 times itself how many times is equal to 4? Well, 2 times 2 is equal to 4, so 2 times itself two times is equal to 4. x is equal to 2:
[tex]4=2^{2}[/tex]
Either way works. If you have any more questions, let me know! :)

The function f(x) = −(x + 5)(x + 1) is shown. On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 3, 4), and goes through (negative 1, 0). What is the range of the function? all real numbers less than or equal to 4 all real numbers less than or equal to −3 all real numbers greater than or equal to 4 all real numbers greater than or equal to −3 Mark this and return
Answer:
All real numbers less than or equal to 4.
f(x) ≤ 4
Interval notation: (-∞, 4]
Step-by-step explanation:
Given the quadratic function, f(x) = -(x + 5)(x + 1), where the vertex occurs at point, (-3, 4):
Since the graph of the parabola opens down, then it means that the vertex is its maximum point. In reference to the vertical points on the graph (i.e., the range values), then the vertex sets the maximum range value of k = 4. This implies that the maximum possible range value is from negative infinity to positive 4.
Therefore, the range of the function is: all real numbers less than to or equal to 4.

The values of A and B that will result in an equation with infinite solutions are 6 and 4
Infinite solution of an equationFor an equation to have infinite number of solutions, the equations on both sides must be the same,
Given the equation
Ax + 4 = 6x + B
If the equation has infinite number of solution, then
Ax = 6x
A= 6
Similarly
4 = B
B = 4
Hence the values of A and B that will result in an equation with infinite solutions are 6 and 4

What is a Cubic equation?Cubic equations are polynomials of degree3.
That means, the maximum degree of polynomial is three.
And the standard form of cubic equation is;
f(x) = ax³ + bx² +cx +d, where a, b, c and d are constant coefficients and a ≠ 0.
Given:
The volume of a rectangular prism is equal to the area of the rectangular faces multiplied by the prism's height.
The volume = height x (the area of the rectangular) ..... equation 1
The volume of a rectangular prism can be expressed as the following cubic function x³ + 125.
We can simplify the function,
x³ + 125,
= x³ + 5³
Here, we can use the formula,
x³+y³ = (x+y) (x²-xy+y²)
So,
x³ + 5³,
= (x+5) (x²-5x+25)
Comparing with the equation 1,
we get,
The height = (x+5) and the area of the rectangular = (x²-5x+25).
Therefore, (x²-5x+25) is the area of the rectangular.
