The heights of two elevators can be modeled by linear functions. At time t = 0. Elevator A is 16 feet above ground floor.
It descends at a rate of 4 feet per minute. The height of Elevator B is shown in the graph.
Which of the following statements are true? Select all that are true.
Answer:
Option B: Elevator A descends at a faster rate than elevator B
Option C: Elevator A will reach the ground first
Step-by-step explanation:
Elevator A: -4x+16
Elevator B: -3x +16
Option B: Elevator A descends at a faster rate than elevator B
Option C: Elevator A will reach the ground first
The calculation is as follows:
For Elevator A: -4x+16
And,
Elevator B: -3x +16
Therefore the above statements are true.

I need help with those 2 the rest I know. I just don’t know what that means.
Answer:
What are the problems?
Step-by-step explanation:
Please actually answer this it has a good amount of points!
The answer is D, "No, because two points with the same x-value have different y-values."
Essentially, there cannot be more than one point on the same x-line. Point (2, 11) and point (2, 2) are on the same x-line, which is 2.

i would recommend; watching a vid abt this!What is the solution to 0.3(12x - 16) = 0.4(12 - 3x)?
Step-by-step explanation:
The solution is one-solution
.3(12x-16)=.4(12-3x) (you do the distributive property)
3.6x-4.8=4.8-.12x (you add 1.2 to both sides)
3.6x-3.6=4.8 (You add 3.6 to both sides)
3.6x=8.4 ( You divide 3.6 both numbers)
x=0.4285...
Its a one-solution
What is the value of n in the equation below 9n-24=4n+6
Answer:
n = 6
Step-by-step explanation:
9n - 24 = 4n + 6 {Subtract 4n from both sides }
9n - 24 -4n = 6
5n - 24 = 6 {Add 24 to both sides}
5n = 6 + 24
5n = 30
n = 30/5
n = 6
Answer:
n=6
Step-by-step explanation:
Simplifying
9n + -24 = 4n + 6
Reorder the terms:
-24 + 9n = 4n + 6
Reorder the terms:
-24 + 9n = 6 + 4n
Solving
-24 + 9n = 6 + 4n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-4n' to each side of the equation.
-24 + 9n + -4n = 6 + 4n + -4n
Combine like terms: 9n + -4n = 5n
-24 + 5n = 6 + 4n + -4n
Combine like terms: 4n + -4n = 0
-24 + 5n = 6 + 0
-24 + 5n = 6
Add '24' to each side of the equation.
-24 + 24 + 5n = 6 + 24
Combine like terms: -24 + 24 = 0
0 + 5n = 6 + 24
5n = 6 + 24
Combine like terms: 6 + 24 = 30
5n = 30
Divide each side by '5'.
n = 6
Simplifying
n = 6

3x + 8 = 26
Reorder the terms:
8 + 3x = 26
Solving
8 + 3x = 26
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 3x = 26 + -8
Combine like terms: 8 + -8 = 0
0 + 3x = 26 + -8
3x = 26 + -8
Combine like terms: 26 + -8 = 18
3x = 18
Divide each side by '3'.
x = 6
Simplifying
x = 6

come help me on my last question
Step-by-step explanation:
what is an equation of the line that passes through the points (1,2) and (2,-1) 
Answer:
[tex]y = - 3x + 5[/tex]
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
Equation
[tex]y = mx + b[/tex]
First we need to know the slope
[tex]slope = \frac{y1 - y2}{x1 - x2} [/tex]
[tex]slope = \frac{2 - ( - 1)}{1 - 2} = \frac{3}{ - 1} = - 3[/tex]
So far the equation will look like this
[tex]y = - 3x + b[/tex]
To get the b you insert a point into the equation like this. I picked point (1,2)
[tex]2 = - 3 \times 1 + b[/tex]
[tex]b = 5[/tex]
We could also check it with the other point and see if we get the same answer.
[tex] - 1 = - 3 \times 2 + b[/tex]
[tex]b = 5[/tex]
So the equation is
[tex]y = - 3x + 5[/tex]

Jerome and his brother stayed at the carnival from 4pm to 8pm they spent 90 minutes watching the magic show what percentage of the evening did they spend at the magic show
Answer:
Percentage of time spend in magic show = 37.5%
Step-by-step explanation:
Given:
Total time 4pm to 8pm = 4 hours = 4 x 60 = 240 minutes
Time spend in magic show = 90 minutes
Find:
Percentage of time spend in magic show
Computation:
Percentage of time spend in magic show = [Time spend in magic show / Total time]100
Percentage of time spend in magic show = [90 / 240]100
Percentage of time spend in magic show = 37.5%
Answer:37.5%

Answer:
[tex]\frac{3}{5}[/tex]
Step-by-step explanation:
When finding the tangent of an angle, tangent of that angle is opposite over adjacent. So, 6 is the opposite side of angle G, and 10 is the adjacent side of angle G. Put [tex]\frac{6}{10}[/tex], which simplifies to [tex]\frac{3}{5}[/tex].

write the equation. the output of a function is 6 more than 2 times the input.
Answer:
y = 2x+6
Step-by-step explanation:
Let the output value be y
Let the input value be x
the output of a function is 6 more than 2 times the input
2 times the input is expressed as 2x
6 more than 2 times the input is expressed as 2x + 6
Since the output of a function is 6 more than 2 times the input, we will equate y to the resulting equation to have;
y = 2x + 6
Hence the required equation is y = 2x+6

Help please The actual distance between Apple Street and Pear Road is 8 miles. On a map, the distance is 3.5 inches. What proportion can you form to determine the scale on the map? 1 inch = ?
Answer:
1 in on the map = [tex]\frac{16}{7}\ miles[/tex] on the street
Step-by-step explanation:
Represent the actual distance as y and the map distance as x
So:
x = 3.5in when y = 8 miles
Required
Determine the proportion
The proportion of map measurement to actual measurement is:
[tex]x : y[/tex]
This gives:
[tex]3.5\ in : 8\ miles[/tex]
Divide by 3.5
[tex]\frac{3.5\ in}{3.5} : \frac{8\ miles}{3.5}[/tex]
[tex]1\ in: \frac{8\ miles}{3.5}[/tex]
Simplify the fraction
[tex]1\ in: \frac{8 * 2\ miles}{3.5*2}[/tex]
[tex]1\ in: \frac{16\ miles}{7}[/tex]
[tex]1\ in: \frac{16}{7}\ miles[/tex]
This means that:
1 in on the map = [tex]\frac{16}{7}\ miles[/tex] on the street
