Linear function A and linear function B both have the same input values as shown below. Why will the output values for linear function A always be different than the corresponding output values for linear function B? The initial values of the two functions are different, and the rates of change of the two functions are also different. The initial values of the two functions are different, and the rates of change of the two functions are the same. The initial values of the two functions are the same, and the rates of change of the two functions are different. The initial values of the two functions are the same, and the rates of change of the two functions are also the same.
Answer:The initial values of the two functions are different, and the rates of change of the two functions are the same.
Step-by-step explanation:
The values will start out different. When you apply the rate of change, because they have the same rate of change, you don't risk them coming out with the same value if the values ended up being just right, they will always remain different.
The differences in the output values for linear function A and function B are a result of varying y-intercepts and slopes in each function. When plotted on a graph, these differences become apparent.
Explanation:The output values for linear function A and function B will differ because of variations in their respective initial values (or y-intercepts) and their rates of change (or slopes). When you plot these output values against the shared input values as a graph of y as a function of x, these differences can be seen visually. For instance, consider the linear equation y = mx + b, where m represents the slope of the line and b is the y-intercept. If function A and B have different y-intercepts or slopes, the output values will differ for the same set of input values.

If prism A and Prism B have a ratio of similarity of 2:3, what is the volume of prism A if Prism B's volume is 56 cubic inches
Answer:
16.6 in³
Step-by-step explanation:
Given the ratio of similarity = 2 : 3, then
the ratio of volumes = 2³ : 3³ = 8 : 27
let the volume of prism A be x then by proportion
[tex]\frac{x}{8}[/tex] = [tex]\frac{56}{27}[/tex] ( cross- multiply )
27x = 448 ( divide both sides by 27 )
x = 448 ÷ 27 ≈ 16.6 ( to 1 dec. place )
Prism A has a volume of approx 16.6 in³

The angles do not share a special relationship.
Answer:
equal angles and vertical angles
Step-by-step explanation:
we know that
Vertical Angles are the angles opposite each other when two lines cross. They are always equal
In this problem
∠14=∠16 -----> by vertical angles
therefore
The answer is
equal angles and vertical angles
Answer:
Vertical angles, equal angles
Step-by-step explanation:
when a transversal passes through two lines, then,
Angles formed in the same side and inside the two lines are same side interior angles.
Angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
Angles formed on opposite sides of the transversal and outside the two lines are alternate exterior angles.
Angles with the same relative position at each intersection are corresponding angles,
While, when two lines intersect each other then the opposite angles formed called vertical angles,
supplementary angles : When the sum of two angles are 180°,
Right angles : angle that has the measurement of 90°,
Equal angles : angles with the same measurement.
Now, vertical angles are always equal angles,
Also, when two parallel lines are cut by the same transversal then the pair of alternate interior angles, alternate exterior angles, corresponding angles are always equal.
Hence, by above definitions it is clear that,
∠16 and ∠14 are vertical and equal angles.

The price of cable service changed from
$35.00 per month to $42.00 per month.
What was the percent of increase?
A. 5%
B. 7%
C. 17%
D. 20%
Answer:
D. 20%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
The new number is the increased price, $42, and the old number is the original price, $35.
percent change = ($42 - $35)/($35) * 100%
percent change = ($7)/($35 min) * 100%
percent change = 0.20 * 100%
percent change = 20%
Since the percent change is a positive number, it is a percent increase.
The percent increase was 20%.

Which is the better buy?
A. 1,323 ounces of topsoil for $410.13
B. 8 pounds of topsoil for $78.08
Answer:
Option. A
Step-by-step explanation:
Covert Ounces to Pounds, or vice versa, I went with pounds.
1323 ounces = 82 pounds.
find the pound to dollar rate
A; 82 ÷ 410.13 = about 5
B; 8 ÷ 78.08 = 9.76
The better buy is A. 1,323 ounces of topsoil for $410.13.
To determine which is the better buy, we need to calculate the price per ounce for both options and then compare them.
First, let's calculate the price per ounce for option A:
1,323 ounces of topsoil for $410.13.
Price per ounce for A = $410.13 / 1,323 ounces.
Now, let's calculate the price per ounce for option B:
Since 1 pound is equal to 16 ounces, 8 pounds of topsoil is equal to
8 × 16 = 128 ounces.
8 pounds of topsoil for $78.08.
Price per ounce for B = $78.08 / 128 ounces.
Next, we compare the price per ounce for both options:
Price per ounce for A = $410.13 / 1,323 ounces $0.310 / ounce.
Price per ounce for B = $78.08 / 128 ounces $0.609 / ounce.
Since the price per ounce for option A ($0.310) is less than the price per ounce for option B ($0.609), option A is the better buy. The customer gets more topsoil for their money with option A.
What is the measure of the missing angle
The sum of the angles of any quadrilateral is 360 degrees. This means that you can make a formula like the one bellow and solve for x:
72 + 107 + x + 91 = 360
270 + x = 360
(270 - 270) + x = 360 - 270
x = 90

Leonardo put a $600 ring on layaway by making a 10% down payment and agreeing to pay $65 a week. How many weeks will it take your nardo to pay off the ring?
Answer: 9 weeks
Step-by-step explanation:
Final answer:
Leonardo will take 9 weeks to fully pay off the $600 ring after making a 10% down payment and weekly payments of $65.
Explanation:
The question is asking how many weeks it will take Leonardo to pay off a ring valued at $600 with a 10% down payment and subsequent weekly payments of $65.
First, calculate the down payment Leonardo makes: 10% of $600 equals $60. Subtract the down payment from the original price to find out the remaining amount Leonardo has to pay, which is $600 - $60 = $540.
Next, divide the remaining amount by the weekly payment: $540 divided by $65 per week equals approximately 8.31, which rounds up to 9 weeks since you can't make a fraction of a payment.
Therefore, it will take Leonardo 9 full weeks to pay off the ring.
Anna wants to put a fence around a rectangular garden plot that measures 9 feet by
18 feet. She wants to place posts at the corners of the plot and every 2 feet around
the perimeter of the plot. How many posts does she need?
The answer is:
Anna will need 27 posts.
Why?To calculate how many post does she need to place at the corners and every 2 feet around, we need to calculate the perimeter of the garden plot.
So, we can calculate the perimeter of the garden plot (rectangle) using the following formula:
[tex]Perimeter=2height+2width[/tex]
We know that:
[tex]height=9ft\\width=18ft[/tex]
Then, calculating the perimeter of the garden plot, we have:
[tex]Perimeter=2height+2width[/tex]
[tex]Perimeter=2*9ft+2*18ft=18ft+36ft=54ft[/tex]
Now, calculating how many post she will need, we have:
[tex]No.Post=\frac{Perimeter}{DistanceBetweenPost}\\\\\frac{54feet}{2feet}=27posts[/tex]
Hence, we have that Anna will need 27 posts.

Combine Like Terms:
=7x^2+−3x+5x+−6
=(7x^2+2x+−6 )
Answer:
=7x^2+2x−6
Final answer:
The sum of (7x² - 3x) and (5x - 6) is found by combining like terms, resulting in 7x² + 2x - 6, which is option C.
Explanation:
To solve the algebraic addition (7x²-3x) + (5x-6), you need to combine like terms.
First, identify and group like terms from both expressions. Like terms are those that have the same variable raised to the same power.
Combine the coefficients (numerical values) for each group of like terms.
Now, let's go through each step:
For the x2 terms: 7x2 (from the first polynomial) has no like term in the second polynomial, so it remains as is.
For the x terms: -3x (from the first polynomial) and +5x (from the second polynomial) combine to give 2x.
Lastly, the constant terms: -6 (from the second polynomial) also has no like term in the first polynomial, so it remains as is.
By combining these, the result is 7x² + 2x - 6, which corresponds to option C.

Find the graph of the inequality y>-1/6x+1
what we do is, we simply draw the graph for its EQUALITY counterpart, namely [tex]\bf y=-\cfrac{1}{6}x+1[/tex].
then we check the regions on both sides of the graph, in this case we can check say the point (0,0) for simplicity, and
[tex]\bf y>-\cfrac{1}{6}x+1\qquad (0,0)~~ \begin{cases} x=0\\ y=0 \end{cases}\implies 0>-\cfrac{1}{6}(0)+1\implies 0>1[/tex]
now, is 0 > 1? is 0 really greater than 1? nope, is smaller, thus the area where the point (0, 0) is at is the false region, so that's the area we do NOT shade, thus the other region must be the true region and that's the one we shade.
the ">" sign means, that "y" is greater than, NOT equals to but greater, thus the values at the borderline are not included, and thus is a dashed line.

Which of the following could be the graph of this equation?
Answer: OPTION C.
Step-by-step explanation:
Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.
For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).
Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.
Therefore, you need to search the option that shown the graph wich contains the point (1,-3).
Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).
This is the graph of the option C.
