What is the slope of the line that passes through
(−2, 3) and (5, −6)
a.-1/2
b.−1
c.-9/7
d. I don't know.
Answers
Start with the slope formula.
m = y₂ - y₁ / x₂ - x₁
m = -6 - 3 / 5 - -2
m = -9 / 7
So the slope is -9/7.
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]
?
Answers
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]

Given the function f ( x ) = − 1 x + 3 x 4 , f(x)=− x 1 + 4 3 x , find f ′ ( 4 ) . f ′ (4). Express your answer as a single fraction in simplest form.
Answers
Step-by-step explanation:
The question is not well written. Let us say the function given as expressed as;
f(x) = -1/x + 3/x⁴
f'(x) means we are to differentiate the function with respect to x;
Given f(x) = axⁿ
f'(x) = naxⁿ⁻¹
f(x) = -x⁻¹ + 3x⁻⁴
Applying the differentiation formula we will have;
f'(x) = -1(-x⁻²)+(-4)3x⁻⁴⁻¹
f'(x) = x⁻²-12x⁻⁵
Express as a fraction
f'(x) = 1/x²-12/x⁵
To get f'(4), we will have to substitute x = 4 into the resulting expression
f'(4) = 1/4²-12/4(5)
f'(4) = 1/16-12/20
f'(4) = 1/16-3/5
Find the LCM
f'(4) = (5-48)/80
f'(4) = -43/80
Note that the function used was assumed but the same method can be employed to any other functions.

Alice rode her bicycle the same number of miles every day for 17 days. She
rode a total of 68 miles during these 17 days. At this rate, how many miles did
Alice ride her bicycle in 1 day?
Answers
Answer: 4
Step-by-step explanation:
Alice ride her bicycle in 1 day for a distance of 4 miles.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given that,
Alice rode her bicycle the same number of miles every day for 17 days.
Let x be the number of miles that Alice rode for 1 day.
She rode x miles for 17 days.
Total number of miles that she rode in 17 days = 68 miles
So, we have,
17x = 68
Dividing both sides by 17,
x = 4
Hence the number of miles Alice rode in 1 day is 4 miles.

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.
Answers
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
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
Answers
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

Answers
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 :)

y equals -x plus 2

Given that :
Amount of potting soil in bag = 9 cups
Size of scooping cup = 3/4 cup
The number of times scooping will be done to use entire bag of potting soil will be ;
(Amount of potting soil in bag ÷ size of scooping cup)
(9 ÷ 3/4)
9/ 1 * 4/3
= 36/3

Andrea bought tacos from a food truck and left 25% tip of $2.00. What was the price of Andreas tacos, before tip?
Answers
If 2.00$ is 25% multiply by 4 which would give you the original price of 8$, plus tip that’s 10$. However the answer is, Andreas tacos, before tip, were 8$.
Answer:
$8
Step-by-step explanation:
25% is .25, also known as 1/4. So if you think of it that way, $2 is 1/4 of the entire payment that was added to it. 2*4 is 8, so the price of the tacos was $8 before any tip was added. Andrea paid $10 in total if you include the tip.

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?
Answers
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
