Consider the data shown on the graph.
• The y-intercept represents the base price of $ drag and drop answer here for airfare from NYC
• The slope represent a cost of drag and drop answer here cents per mile traveled.
• If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be drag and drop answer here
• If the cost per mile changed to 50 cents, the new equation would be drag and drop answer here
Answers
Answer:
Step-by-step explanation:
THE ANSWER IS 200 , 30, Y=50+0.30X, Y=200+ 0.50X
The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
EXPLANATION
The equation given can be express as
y = 0.25x + 50
y = 0.30x + 40
Since, both equations are functions
Equate the two functions together
0.25x + 50 = 0.30x + 40
Collect the like terms
0.25x - 0.30x = 40 - 50
x(0.25 - 0.30) =-10
x(-0.5) = -10
-0.5x = -10
Divide both sides by -0.5
-0.5x / -0.5 = -10/-0.5
x = 10/0.5
x = 20
When collecting the like terms, we isolate values with the same variables from values with a different variables.
If a positive sign crosses an equality sign it automatically becomes a negative sign and if a negative sign crosses an equality operator it automatically becomes a positive sign.
Hence, The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.

x greater-than 272
x less-than-or-equal-to 272
x less-than 272
x greater-than-or-equal-to 272
Answers
Answer:
1200-928 = 272 for the rest of the month Clarissa has to spend.
Step-by-step explanation:
So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over.

Oceanside Bike Rental Shop charges a 13 dollar fixed fee plus 9 dollars an
hour for renting a bike. Carlos paid 58 dollars to rent a bike. How many
hours did he pay to have the bike checked out? *
Answers
Answer: 5 hours
Step-by-step explanation:
Carl paid $58 dollars in total and this included the fixed dollar fee and the variable amount of $9.
To find the number of hours, first deduct the fixed component:
= 58 - 13
= $45
$45 was spent as a result of hourly fee. The number of hours is therefore:
= Total hourly cost/ Cost per hour
= 45 / 9
= 5 hours
After a very successful year, Cheap-Rentals raised salaries by a scale factor of `\frac{11}{10\ }`. If Luan now makes $14.30 per hour, what did she make before?
Answers
Answer:
$13
Step-by-step explanation:
Given that :
Increase in salary factor = 11/10
New salary = $14.30
Initial salary = x
To obtain the value of the initial salary,
The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary
11 / 10 * x = 14.30
1.1x = 14.30
x = 14.30 / 1.1
x = $13
Hence.initial salary per hour = $13

Answer:
50
Step-by-step explanation:
We know angles in a straight line add up to 180, therefore:
2x + 50 + 30 = 180
2x + 50 = 180 - 30
2x + 50 = 150
2x = 150 - 50 = 100
2x = 100
x = 50
Answer:
Step-by-step explanation: Since we know the angle of a line is 180 degrees. We can use that.
1. 180-30 because we already know that angle is 30 degrees.
2. We are left with 150 degrees so we know the large angle is 150 degrees to check we do this.
3. 150=2x+50
4. 100=2x Divide both sides by two and get
5. x=50
About 32% of the 104 children ate a school picnic ate hamburgers. The rest ate hotdogs. How many children ate hotdogs at the picnic
Answers
Answer: 71 children ate hotdogs at the picnic.
Step-by-step explanation:
Given: About 32% of the 104 children who ate a school picnic ate hamburgers.
The number of children ate hamburger = 32% of (104 children)
= 0.32 x 104
= 33.28 ≈ 33
Thus, the number of children ate hamburger = 33
Number of children ate hotdogs = 104-33 = 71
Hence, 71 children ate hotdogs at the picnic.

Answer:
C= 93⁰, B= 64⁰, D= 23⁰
Step-by-step explanation:
180= (4x + 1) + (3x - 5) + x⁰
180= 4x+1 +3x-5 +x
180= 8x - 4
184= 8x
184/8= x
23=x
therefore
C= (4(23) +1)
C= 93
B= (3(23)-5)
B= 64
D= 23
93⁰+64⁰+23⁰=180⁰

SAS Theorem
Step-by-step explanation:
You can tell that the triangles are similar because of the SAS (side-angle-side) theorem.
This is because you already know that two of the sides are congruent since AB and CD were shown to be congruent in the image, and AC and CA are congruent because they're shared. You know that there are similar angles because of the Alternate Interior Angles Theorem*: because of it, you know ∠ACD and ∠CAB are similar because the lines that their transversal intersects are parallel.
*The Alternate Interior Angles Theorem states that if two lines are parallel, the alternate interior angles formed by a transversal are congruent.

Step-by-step explanation:
Felicity cuts 27 equal strips from a 6-yard spool of ribbon. Which expressions show the number of yards for one strip of ribbon
From the above question:
27 equal strips of ribbon = 6 yards of spool
1 strip of ribbon = x yards
Cross Multiply
27 strips of ribbon × x yards = 6 yards × 1 strip of ribbon
x yards = 6/27
x yards = 2/9 yards
Therefore, for 1 strip of ribbon we need 2/9 yards
