The Allied Taxi Company charges $2.50 to pick up a passenger and then adds $1.95 per mile. Isaac was charged $27.46 to go from one city to another. If x represents the
BIG POINTS IF YOU ANSWER CORRECTLY PLEASE ANSWER ASAP number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth?
1.95x + 2.50 = 27.46; Isaac traveled 15.4 miles.
1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.
2.50x + 1.95 = 27.46; Isaac traveled 11.8 miles.
2.50x + 1.95 = 27.46; Isaac traveled 10.2 miles.
Answer:
It should be the second one
Step-by-step explanation:
Answer:
The answer is - 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.

if
[tex]f(x) = \sqrt{x} + 12[/tex]
and
[tex]g(x) = 2 \sqrt{x} [/tex]
what is the value of
[tex](f - g)(144)[/tex]
?
Answer:
0
Step-by-step explanation:
We have the two functions:
[tex]f(x)=\sqrt{x}+12\text{ and } g(x)=2\sqrt{x}[/tex]
And we want to find (f-g)(144).
This is the same thing to f(144)-g(144).
So, let’s determine the value of f(144) and g(144) first:
[tex]\begin{aligned} f(144)&=\sqrt{144}+12 \\ &=12+12 \\ &=24\end{aligned}[/tex]
And:
[tex]\begin{aligned} g(144)&=2\sqrt{144} \\ &=2(12) \\ &=24 \end{aligned}[/tex]
Hence:
[tex]\begin{aligned} (f-g)(144) &= f(144)-g(144) \\ &=24-24 \\ &=0 \end{aligned}[/tex]
Our final answer is 0.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex](f - g)(x) = \sqrt{x} + 12 - 2 \sqrt{x} \\ [/tex]
[tex](f - g)(x) = - \sqrt{x} + 12[/tex]
[tex](f - g)(144) = - \sqrt{144} + 12[/tex]
[tex](f - g)(144) = - \sqrt{ {12}^{2} } + 12 [/tex]
[tex](f - g)(144) = - (12) + 12[/tex]
[tex](f - g)(144) = - 12 + 12[/tex]
[tex](f - g)(144) = 0[/tex]

A certain map shows two roads. Road A is 1 1 2 miles long but is 1 7 8 inches long on the map. What is the unit rate for inches per mile on this map? If road B is 8 miles long, how long is road B on the map?
Answer:
a) What is the unit rate for inches per mile on this map?
= 5/4 inches per mile
b) If road B is 8 miles long, how long is road B on the map?
10 inches on the map
Step-by-step explanation:
a) A certain map shows two roads. Road A is 1 1/2 miles long but is 1 7/8 inches long on the map. What is the unit rate for inches per mile on this map?
Unit rate for inches per mile is calculated as:
1 7/8 inches/ 1 1/2 miles
= 15/8 / 3/2
= 15/8 × 2/3
= 5/4 inches per miles
b) If road B is 8 miles long, how long is road B on the map?
The unit rate is given as:
5/4 inches per miles
Hence,
Road B = 8 miles long
The length of Road B on the map =
5/4 inches per miles × 8 miles
= 10 inches

Answer:
y = -x + 2
Step-by-step explanation:
For any linear equation, the equation of the line can be written in the form 'y=mx+c'. In this form, m is the slope and c is the y-intercept. We can figure out both these things using the graph.
The slope is like the incline/decline and can be found by getting two points on the line, say (x1,y1) and (x2,y2) and using the following formula:
m = (y2-y1) / (x2-x1)
So lets take two points: (-1,3) and (2,0)
m = (0-3)/(2-(-1))
m = -3/3
m= -1
The y intercept (c) is the value for x when the line crosses the y-axis.
From the graph we can see that the line crosses the y axis when x=2
∴ c = 2
Now that we know the slope and intercept, we just sub them into the formula:
y = mx +c
y = -x + 2
Let me know if you have questions :)
Answer:
y equals -x plus 2
Step-by-step explanation:
for any linear equation, the equation of the line can be written in the form 'y=mx+c'. In this form, m is the slope and c is the y-intercept. We can figure out both these things using the graph.
the slope is like the incline or decline and can be found by getting two points on the line, say (x1,y1) and (x2,y2) and using the following formula:

Megan's bank account is charged $9.95 per month for an online newspaper subscription how can you represent a change in her account balance after three months of charges
Answer:
T = C - (9.95 * 3)
Step-by-step explanation:
The account balance total can be calculated with the following equation where the variable T represents the final balance while the variable C represents her current balance before the three months...
T = C - (9.95 * 3)
The monthly charge is multiplied by the three months that Megan will be charged and then discounted from her current balance in order to give the new Total Balance after paying the subscription for the three months.

The area of a square is (9x2 − 12x + 4) square units. Determine the length of each side of the square by factoring the area expression completely
Step-by-step explanation:
9x2 − 12x + 4 = 18 - 12x + 4 = 22 - 12x = 2(11 - 6x)
length of 1 side = ± sqrt 2(11-6x) (rej neg value)
The temperature of a liquid in an experiment starts at 0 degrees Celsius. The experiment calls for the temperature of the liquid to change at a rate of –0.6 degree Celsius per minute. How long will it take for the liquid to reach –10.5 degrees Celsius? 2Points Remember to divide to find the minutes.
Answer:
It will take 17.5 minutes or 17 minutes and 30 seconds to reach -10.5 degrees celsius
Step-by-step explanation:
Starting at 0 degrees, we have a change of -0.6 degree celsius per minute
We want to know how long it will take for the liquid to reach - 10.5 degrees Celsius
The total difference between the two is;
-10.5 - 0 = -10.5
The change per minute is -0.6
So the number of minutes it will take will be;
-10.5/-0.6 = 17.5 minutes
Is there a constant rate of change? If yes, what is the rate?

-x + 1 = x + 21
solve for x
I need this asap
Answer:
x = -10
Step-by-step explanation:
-x + 1 = x + 21
(given)
__________
-x + 1 = x + 21
+x +x
(addition property of equality)
(add the x term on both sides to cancel out -x)
__________
1 = 2x + 21
-21 -21
(subtraction property of equality)
(subtract by 21 on both sides to get rid of the constant term on the x side)
________
-20 = 2x
÷2 ÷2
(division property of equality)
(divide to get rid of the coefficient of 2 in the x term)
_______
-10 = x
(symmetric property of equality)
(switch both sides so that x is on the left)
_______
x = -10
________________________________
Proof by substitution:
x = -10 because
x = -10 → -x + 1 = x + 21 → -(x) + 1 = (x) + 21 → -(-10) + 1 = (-10) + 21 → 10 + 1 = 21 - 10 →

Answer: 5/8
Step-by-step explanation:
When multiplying two fractions together, always try to cross-cancel if possible as your first step.
In this problem the 3 and 6 reduce to 1 and 2.
Next we simply multiply across the numerators and multiply across the denominators and we have our answer which is 5/8

You newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton Descartes have 5040 volunteer min altogether how many min do you volunteer
Complete question is;
You, newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton and Descartes. You all have 5040 volunteer min altogether. how many min do you volunteer?
Answer:
2520 volunteer minutes
Step-by-step explanation:
You have 2 times as many volunteer minutes as Newton and Descartes.
Now, if Newton and Descartes each have x volunteer minutes, it means you have 2x volunteer minutes.
Since the total volunteer minutes of the 3 of you is 5040,then we have;
2x + x + x = 5040
4x = 5040
x = 5040/4
x = 1260
Since you have 2x volunteer minutes, then you have: 2 × 1260 = 2520 volunteer minutes
