If f(x) = 3-8(x-2), what is f(-9)
Answer:
f(- 9) = 91
Step-by-step explanation:
To evaluate f(- 9) substitute x = - 9 into f(x), that is
f(- 9) = 3 - 8(- 9 - 2) = 3 - 8(- 11) = 3 + 88 = 91
Answer:
91 just fill in -9 to x

Determine any data values are missing from the table assuming that the data represents a linear function.
Answer:
Missing x:0
Missing y:1
Hence, option b is correct.
Step-by-step explanation:
Given the table
x y
-9 3
-6 2
-3 missing
missing 0
As we know that the linear function has a constant common difference between the x values and y values.
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by -3.
i.e. -9-(-6)=-3
-6-(-3)=-3
So the missing x value will be:
-3-(x)=-3
-3-(0)=-3
Therefore, the missing x value wil be: 0
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by 1.
i.e.
3-2=1
2-y=1
y=1
Therefore, the missing y-value will be 1.
Therefore,
Missing x:0
Missing y:1
Hence, option b is correct.

D. Robertas boat was farther from the dock at the beginning, and it traveled more quickly
I'll give u 5 stars if you right
Answer:
C
Step-by-step explanation:
John:
y = x +30
y = 5x + 50
Roberta:
y = 5x + 2
Conclusion:
You can see that John's boat was farther from the start and traveled faster because when John traveled for 5 hours, he traveled 50 miles while Roberta only traveled 25 miles for the same time.
Hello There!
Your correct answer is C.
There is no way to explain but when I put A it is incorrect but when I read that it was wrong I wanted to let other people that it was incorrect. Thanks!
Hope this helps to all you ape.x learners!!

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth.
Answer: 2.9 minutes.
Step-by-step explanation:
Given: Rate of filing the tank = 12 gallons per minute
Total volume of reservoir = 35 gallons
Time taken to fill the reservoir = [tex]\dfrac{\text{Total volume of reservoir }}{\text{Rate of filing the tank}}[/tex]
[tex]=\dfrac{35}{12}\approx2.9[/tex]
hence, time taken to fill the reservoir = 2.9 minutes.

Jack and Jillian sell apples at a produce stand. Jillian earns $2 for each bag of apples she sells. At the end of the week, Jack has earned $8 less than Jillian. The following expression shows Jack's earnings:
2x − 8
In the expression, what does the first term represent?
1 Jack's earnings at the end of the week
2 The number of bags of apples Jillian sold
3Jillian's earnings at the end of the week
4 The number of bags of apples Jack sold
We are given that Jack and Jillian sell apples at a produce stand .
We are given that an expression which shows Jack's earning=2x-8
We have to find that first term what represent in the given expression
Jillian earns for each bag of apples she sells=$2
Let Jillian sold number of bags of apples =x
Then ,Jillian earn total at the end of the week =
Jack has earned $ 8 less than Jillian earn
Therefore, total earning of jack=
In the given expression the first term 2x represent the earning of Jillian.

(-6k+7)-(7k+5)
Please help :)
9514 1404 393
Answer:
5b +3r -12k +5-13k +2Step-by-step explanation:
It looks like you want to simplify the sums.
1. (3r -4) -(-5b -3) = 3r -4 +5b +3 = 5b +3r +(-4+3)
= 5b +3r -1
__
2. (-4k -1) -(-6k -6) = -4k -1 +6k +6 = (-4+6)k +(-1+6)
= 2k +5
__
3. (-6k +7) -(7k +5) = -6k +7 -7k -5 = (-6-7)k +(7-5)
= -13k +2

Given the figure below, find the measure of
Answer:
x = 23.125°
Step-by-step explanation:
∠ACF = ∠GCB (vertically opposite angles)
3x + 5x - 5 = 180° (angles on a straight line are supplementary)
8x = 185°
x = 23.125°
This is a question on angles. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
