Step-by-step explanation:
f(x)=2x+1 is a linear function, and not a exponential function.
This is because exponential functions, usually have exponents (exponential). It would look more like a roller coaster. It's either going up, or down.

Three brothers share a 5 gigabyte (gb) family data plan on their cell phones. One month. Aaron used. 2.3gb, Brian
used 1.1gb, and Caleb used 1.6gb. If the total bill for the
month $110, how should they split up the bill so they pay the
same fraction of the bill as the data they used?
Step-by-step explanation:
[tex] \frac{5gb}{110} = \frac{2.3gb}{x} [/tex]
→ x = 2.3 ×110÷5 = 50.6 $ Aaron pay
→Brian = 1.1 × 110 ÷5=24.2$
Caleb = 110 - ( 24.2 + 50.6 ) = 110 -74.8 = 35.2$
Aaron should pay $50.60, Brian should pay $24.20, and Caleb should pay $35.20 to split the bill in proportion to the data they used.
How to determine the way to split up the billTo split the bill among the three brothers in proportion to the data they used, we need to calculate the fraction of the total data used by each brother and allocate the bill accordingly.
The total data used by the three brothers is 2.3gb + 1.1gb + 1.6gb = 5gb.
Now, let's calculate the fraction of the bill that each brother should pay based on their data usage:
Aaron's fraction = 2.3gb / 5gb = 0.46
Brian's fraction = 1.1gb / 5gb = 0.22
Caleb's fraction = 1.6gb / 5gb = 0.32
The sum of these fractions should equal 1, representing the entire bill.
To allocate the bill, we multiply each brother's fraction by the total bill amount:
Aaron's payment = 0.46 * $110 = $50.60
Brian's payment = 0.22 * $110 = $24.20
Caleb's payment = 0.32 * $110 = $35.20
Therefore, Aaron should pay $50.60, Brian should pay $24.20, and Caleb should pay $35.20 to split the bill in proportion to the data they used.

find the slope (-2,-4) (-5,5)
Answer:
Your answer would be Slope m = -3
Step-by-step explanation:
Step 1: Graph the points on a coordinate plane( refer to image!)
Whenever your trying to find a slope of 2 order pairs, remember this
m = rise/run. ( Slope = rise over run.) = Δy/Δx
Now we solve:
M = rise/run = Δy/Δx
M = y2 - y1/x2-x1
M = 5 - (-4) / -5-(-2)
So we get M = 9/-3 and 9 divided by -3 is -3
So, the slope of (-2,-4) and (-5,5) is -3.

Step-by-step explanation:
10x - 30 and 3x + 15 are same- side interior angles and sum to 180° , so
10x - 30 + 3x + 15 = 180 , that is
13x - 15 = 180 ( add 15 to both sides )
13x = 195 ( divide both sides by 13 )

What is the area of this polygon?
Enter your answer in the box.
Answer:
42 square units
Step-by-step explanation:
Think of the polygon as being the rectangle GPST added to the triangle PES.
total area = area of rectangle GPST + area of triangle PSE
= LW + bh/2
= GT × GP + PS × h / 2
= 7(5) + 7(2)/2
= 35 + 7
= 42
Just a note of the height of the triangle. The height of triangle PSE, h, is the segment with endpoints E and point (2, 2), so its length is 2.

The point-slope form of a line that has a slope of –2 and passes through point (5, –2) is shown below.
y + 2 = –2 (x–5)
What is the equation in slope-intercept form?
Answer:
y = -2x + 8
Step-by-step explanation:
Solve for y
y + 2 = -2(x - 5)
y + 2 = -2x + 10
y = -2x + 8
y = -2x + 8
Slope-int. form is written as y=mx+b
m is your slope and b is you y intercept
You first will evaluate the -2(x-5) to get:
-2x + 10
Then you'll subtract 2 from each side to get the y alone:
y = -2x + 8

If x varies inversely as t, and x = 8 when t = 6, find t when x = 12-
=
Answer:
t = 4
Step-by-step explanation:
given x varies inversely as t , then the equation relating them is
x = [tex]\frac{k}{t}[/tex] ← k is the constant of variation
To find k use the condition x = 8 when t = 6 , then
8 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
48 = k
x = [tex]\frac{48}{t}[/tex] ← equation of variation
when x = 12 , then
12 = [tex]\frac{48}{t}[/tex] ( multiply both sides by t )
12t = 48 ( divide both sides by 12 )
t = 4

Julia is playing a board game with a spinner that has 6 equally-sized segments: 2 1 3 6 4 5 If she spins a “6” then she gets to move forward 6 spaces and spin again. Then, if she spins a “2”, she wins. Assume that the outcome of one spin doesn't affect the outcome of future spins. а What is the probability that Julia spins a “6” followed by a “2”? Round your answer to two decimal places.
Using it's concept, it is found that there is a 0.0278 = 2.78% probability that Julia spins a “6” followed by a “2”.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 6 equally spaced segments, one of which represents 6, hence the probability that Julia spins a “6” is [tex]P(A) = \frac{1}{6}[/tex].The trials are independent, hence the probability that she spins a “2” is [tex]P(B) = \frac{1}{6}[/tex].The probability of both events is given by:
[tex]p = P(A)P(B) = \frac{1}{6} \times \frac{1}{6} = \frac{1}{36} = 0.0278[/tex]
0.0278 = 2.78% probability that Julia spins a “6” followed by a “2”.
