Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20
largest to smallest

So....
.1 is 1/10 of 1.
.3 is 3/10 of 1.
MEANING .1 is smaller than 3.
1/2 is SMALLER than 3/4.
1/2 is equal to 2/4.
.85 is EQUAL to 85/100 rounded up to 9/10 making it larger than numbers such as .79 and 1/2.

Heather took one of her friends out to lunch. The lunches cost $100 and she paid 9% sales tax. If Heather left a 15% tip on the $100, how much in total did she pay?
Answer:
124 is the total
Step-by-step explanation:
100 * .09 = 9
100 * .15 = 15
15+ 9 + 100 = 124

What is the abbreviation for slope?
I
Answer:
the letter m
Step-by-step explanation:
I don't believe there IS one, however I would say as a educated guess that it would most likely be SLO. or SP. I would normally just look it up from different sources and explain it to you, however my school has the term abbreviation against the rules for searching.
I hope this helps and have a Merry Christmas,

Answer:
x = -36
Step-by-step explanation:
Distribute 1/2 to x - 12 first to get 1/2x - 6. Combine -6 and 4 together to get -2. Your equation should now be 1/3x - 8 = 1/2x - 2. Subtract 1/3x on both sides to get 1/6x. Add 2 on both sides to get -6. Since you are dividing a fraction number, you want to do the opposite and instead multiply 6 on both sides to get your x value which is -36.
Answer:
x = -36.
Step-by-step explanation:
1/3x - 8 = 1/2(x - 12) + 4
multiplying through by the LCM 6;
6 × 1/3x - 6 × 8 = 6 × 1/2(x - 12) + 6 × 4
2x - 48 = 3(x - 12) + 24
2x - 48 = 3x - 36 + 24
2x - 48 = 3x - 12
-48 + 12 = 3x - 2x
-36 = x
hence x = -36.

An online shopping club has 14,000 members when it charges $9 per month for membership. For each $1 monthly increase in the membership fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # membersmonthly fee.
9514 1404 393
Answer:
R = -500x^2 +9500x +126000
Step-by-step explanation:
The revenue is the product of number of members and membership fee. For a price increase of x, the number of members is said to be ...
14,000 -500x
For a price increase of x, the membership fee will be ...
9 +x
Then the revenue is ...
R = (14000 -500x)(9 +x)
R = -500x^2 +9500x +126000

Which function represents the graph of y=4x−1?
Answer:
y=4^x −1
x intercept is the point when y = 0, so you sub in 0 for y:
0 = 4^x - 1
4^x = 1
Any number excluding 0 that is raised to the the exponent 0 always equals 1, 0^0 is undetermined.
x = 0
x intercept = (0,0)
If the x intercept is at the origin (0,0) than the y intercept is also (0,0)
s is the only line that passes through (0,0)
Write the 5th and 6th terms of the sequence:
2/9, 2/3, 2, 6, ...
Answer:
18, 54
Step-by-step explanation:
6/2 = 3
2/(2/3) = 3
Each term is the previous term multiplied by 3.
6 * 3 = 18
18 * 3 = 54
Answer: 18, 54

Step-by-step explanation:
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope intercept form. Identify the slope and y- intercept of the equation. Be sure to show all your work.
2x + 3y= 1470
2x + 3y -2 = 1470 subtract 2x from both sides
3y= 1470 -2x simplify
3y/3= 1470/3 -2x/3 divide both sides by 3
y= -2/3x +490 simplify
-⅔ is the slope and 490 is the y- intercept
2. Describe how you would graph this line using the slope- intercept method. Be sure to write in full sentences.
Start at 490 on the y axis. After that you would use rise over run, down 2 units and right three. Do this until you reach the end of the graph, then go oppisite; up 2 left 3
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
I CANNOT figure out how to make the equation into notation form. Can someone please help?

4. If the point (-2-4) was reflected in the x-axis and then translated five units right and seven units down, which of the following would be the coordinates of its image?
Answer:
(3,-3)
Step-by-step explanation:
when you reflect over the x-axis it puts your point at (-2,4) then when you translate five units right it puts you at (3,4) and when you translate 7 units down you are at (3,-3)
If f(x) = 3x - 5, then f(2) =1.
step by step:
if its f(2) then u replace x with 2 so it would look like
f(2) = 3(2) - 5
3 times 2 is 6
6-5 is 1
thats how u solve it
Yes you are correct. It equals 1

Determine if (1, 3) is a solution to the given system of linear equations. 5x+y=8 x+2y=5 (1 point)
No, because substituting the given ordered pair yields two true expressions.
No, because substituting the given ordered pair doesn't yields two true expressions.
Yes, because substituting the given ordered pair doesn't yield two true expressions.
Yes, because substituting the given ordered pair yields two true expressions.
5x+y=8 equation 1
x+2y=5 equation 2
Subsitute (1,3) in bothe equations if the right side is equal to.the left side of the equation then (1,3) is a solution
5(1)+3=8
1+2(3)=7
7 isn't equal to 5 so 1,3 is NOT a solution for this system of equations

Aqua town charges $4.50 admission plus $0.75 for each ride. The cost at Wet World is $2.50 admission plus $1.25 per ride.
a) Write an equation for the cost of going to Aqua Town.
b) Write an equation for the cost of going to wet world.
c) How many rides would you have to ride for both water parks to cost the same amount? What would the cost be? Write a system of equations( put your two equations equal to each other)to solve for x and y. Write your answer in the form (x,y).
Answer:
4 rides at each park will result cost $7.50.
Step-by-step explanation:
a) A(r) = 4.50 + 0.75r
b) W(r) = 2.50 + 1.25r
c) 4.50 + 0.75r = 2.50 + 1.25r
0.50r = 2
r = 4
