If you can figure this out you get brainliest.
Answer:
the answer is F: 6 because you add all the numbers together and then divide by the amount of numbers in the problem
Step-by-step explanation:
Answer:
6 is the answer cause when you add it all up it equals 60 then divide by how many numbers there were and that was 10 numbers so 60÷10=6
Beth finished a race in 4.59 minutes. Ana finished the race in 0.7 minutes less than Beth. Fran finished the race in 1.05 minutes less than Ana.
How many minutes did it take Fran to finish the race?
Answer:
2.84 minutes
Step-by-step explanation:
Subtract the less time of Ana from the intial (Beth) then subtract the amount less of Fran
4.59 - 0.7 = 3.89 minutes
3.89-1.05 = 2.84 minutes

Given g(x) = 2x – 1, solve for x when g(x) = 3.
Answer:
x = 2
Step-by-step explanation:
g(x) = 2x - 1
g(x) = 3
2x - 1 = 3
Add 1 to both sides;
2x = 4
Divide both sides by 2;
x = 2
for f(x) =4x+1 g(x)=x²-5, find (f•g)(x)
Answer:
(f · g)(x) = 4x³ + x² - 20x - 5
General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining Like TermsExpand by FOIL (First Outside Inside Last)Step-by-step explanation:
Step 1: Define
f(x) = 4x + 1
g(x) = x² - 5
(f · g)(x) is f(x)g(x)
Step 2: Find (f · g)(x)
Substitute: (f · g)(x) = (4x + 1)(x² - 5)Expand [FOIL]: (f · g)(x) = 4x³ - 20x + x² - 5Combine like terms: (f · g)(x) = 4x³ + x² - 20x - 5We know that,
[tex] \Large \underline{\boxed{\sf{ (f . g)(x) = f(x) \times g(x) }}}[/tex]
By substituting values :
[tex] \sf : \implies (f . g)(x) = (4x+1) \times (x^{2} -5)[/tex]
[tex] \sf : \implies (f . g)(x) = 4x(x^{2} -5) +1(x^{2} -5)[/tex]
[tex] \sf : \implies (f . g)(x) = 4x^{3} - 20x + x^{2} -5[/tex]
[tex] \sf : \implies (f . g)(x) = 4x^{3} + x^{2} - 20x -5[/tex]
Hence, answer is :
[tex]\underline{\boxed{\sf{(f . g)(x) = 4x^{3} + x^{2} - 20x - 5}}}[/tex]

Phyllis and Chen are saving money to go to a football game. Each friend starts with some money and saves a specific amount each week.
Phyllis made a graph to show the total she has saved at the end of each week.
Chen wrote an equation to show the total, y, he has saved at the end of each week, x.
y = 15x + 15
Compare the amount that each friend has when both friends start saving.
Select the correct answer from the drop-down menu to complete the statement.
Phyllis starts with $
Choose... 10,15,25, or 50
and Chen starts with $
Choose... 10,15,25, or 50
.
Answer:
Chen:15$
Phyllis: 50$
Step-by-step explanation:
Hi!
Here's what we have:
Chen's equation and Phyllis's graph.
Let's start with Chen. His equation is y=15x+15, where y is the total and x is the week. Chen's starting amount will be the amount at the zeroth week. Now, the zeroth week is when x = 0 --> y=15(0) + 15 --> y=15
So, Chen starts off with 15$.
Now, looking at the graph, Phyllis starts off at a number between 60 and 40 (we're looking at the y-intercept because that's when x=0)
The only number between 60 and 40 in the answer choices is 50.
Phyllis starts with 50$.
A certain map shows two roads. Road A is 1 1/5 miles long but it is 1 4/5 long on the map. What is the unit rate for inches per mile? If road B is 4 miles long, how long is road B on the map?
Answer: 6 inches
Step-by-step explanation:
Road in inches = 1 ⁴/₅
Road in miles = 1 ¹/₅
Inches per mile = 1 ⁴/₅ / 1 ¹/₅
= 1.5 inches
If the road is 4 miles long, on the map it would be;
= 1.5 * 4
= 6 inches

what are the coordinates of the point on the directed line segment from (-8,8) to (7,-7) that partitions the segment into a ratio of 1 to 4?
Answer:
The coordinates are (-5,5)
Step-by-step explanation:
We use the internal division formula here
(x,y) = (nx1 + mx2)/m+ n , (ny1 + my2)/(m + n)
where m = 1
n = 4
(x1,y1) = (-8,8)
(x2,y2) = (7,-7)
Substituting these values, we have
(x,y) = (4(-8) + 1(7))/5 , (4(8)+ 1(-7)/5
(x,y) = (-25/5, 25/5)
(x,y) = (-5,5)

equation
horizontal asymptote
vertical asymptote
Answer:
Hello,
In order to determine which is the horizontal asymptote remember that the horizontal is always x= something and remember that horizontal is straight from left to right.
So Horizontal asymptote = 2
For vertical asymptote it goes from the bottom of the graph, directly up. Think about it like this, you stand upright...or vertically right? So the vertical asymptote is
y= 0

A right triangle has a leg lengths of 9 units and 12 units. Write an equation that can be used to determine the length of the hypotenuse, c.
Answer:
a^2+b^2=c^2
c=15 units
Step-by-step explanation:
You can use the pythagorean theorem to solve this equation. a^2+b^2=c^2.
If you substitute the leg lengths in, the new equation will be 9^2+12^2=c^2, c being the hypotenuse.
Next, you can simplify it to get 81+144=c^2. Simplifying it further, you get 225=c^2, which means that the length of the hypotenuse is 15. Hope this helped! :)
Answer:
15
Step-by-step explanation:
9^2+12^2=c^2
81+144=c^2
225=c^2
15=c
or you can see that this is a 3,4,5 triangle (just 3 times bigger)

12. Question: Solve the unfinished equation.
1=4
2=16
3=64
4=???
Explain.
Answer:
4 = 256.
Step-by-step explanation:
The formula used in each equation is 4x = Y. So, 41 = 4, 42 = 16, 43 = 64, and 44 = 256.
Answer:
[tex]\huge\boxed{\sf 256}[/tex]
Step-by-step explanation:
The equation used for this unfinished equation is:
[tex]\sf 4^{x} = y\\\\Where \ x \ is \ L.H.S \ and \ y \ is \ R.H.S[/tex]
So,
If x = 1, y = 4
[tex]\sf 4^1 = 4[/tex]
If x = 4 , y = 256
[tex]\sf 4^4 = 256[/tex]
