Answer:
For the first part of 4 questions wrong: he would get 42 points
For the second part 48 points
Step-by-step explanation:
For the first part of 4 questions wrong: he would get 42 points because 50 divided by 2 is 25 and 25 minus 4 is 21 and 21 times 2 is 42.
For the last part I'm guessing x = 1 so again 50 divided by 2 is 25 and 25 minus 1 is 24 and 24 times 2 is 48
I think it is right.
Answer: first one 42
The second one is 50-2x
explanation: score with 4 questions wrong
Available points 50. Points lost=points per question x4=2x4=8 final score 50-8=42
Score with x questions wrong: available points 50 points lost=points per questionx4=2*x=2x final score =available points-points lost =50-2x

slope intercept equation from graph
Answer:
y = 2x+4
Step-by-step explanation:
Hi there,
In this linear graph, we notice that the slope is 2 since the [tex]\frac{rise}{run}[/tex] is [tex]\frac{2}{1}[/tex]. We also notice that this line crosses the y-axis at x = 0. Based on the information we found, we can put it in the linear equation y = mx+b.
Here is what the m and b means for reference:
m = slope
b = y-intercept
The final answer will be y = 2x + 4.
Hope this answer helps clarify this concept. Feel free to ask me questions. Cheers.

On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?
Answer:
30 first-class tickets were sold and 260 coach tickets were sold.
Step-by-step explanation:
Let a first-class ticket be represented by f and let a coach ticket be represented by c.
On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:
[tex]f+c=290[/tex]
The total income was $95,280. Therefore:
[tex]680f+288c=95280[/tex]
We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:
[tex]85f+36c=11910[/tex]
From the first equation, we can subtract f from both sides:
[tex]c=290-f[/tex]
Substitute:
[tex]85f+36(290-f)=11910[/tex]
Distribute:
[tex]85f+10440-36f=11910[/tex]
Simplify:
[tex]49f=1470[/tex]
So:
[tex]f=30[/tex]
From the previous equation:
[tex]c=290-f[/tex]
Substitute:
[tex]c=290-30=260[/tex]
30 first-class tickets were sold and 260 coach tickets were sold.

If the fourth term of an Arithmetic sequence is 48 and the third term is 36...
(A) What is the first term?
(B) What is the twelfth term?
Answer:
1st term is 12
12th term is 144
Step-by-step explanation:
48-36=a4-a3=a1 so a1 is equal to 12 now to get from a3 to a4, you must add 12, so d=12.
a12=12+11*12=12+132=144
Maria has 10 sheets of paper. She cuts some of the sheets into five parts each. After that Maria has 22 pieces in total. How many sheets did she cut?
Answer:
3 sheets
Step-by-step explanation:
It is given that:
Number of sheets Maria had = 10
Maria cut sheets into = 5 parts each
After cutting the sheet, the number of the sheets that Maria fad in total = 22
So Maria cut 1 sheet = 5 parts
Therefore, 1 sheet gives 5 pieces
2 sheets gives 10 pieces.
Similarly 3 sheets gives 15 pieces.
So number of sheets left with Maria = 10 - 3
= 7 sheets
Therefore, now Maria has = 15 + 7
= 22 pieces
Thus, Maria cut 3 sheets of paper.

You are shopping and find a coat that is on sale for 30% off . It is regularly priced at $80 . Your friend tells you that she saw the same coat for $ 80 in another store, but it was 20 % off plus an additional 10% off . Will you save money by going to the other store ? Explain why or why not .
You are shopping and find a coat that is on sale for 30% off . It is regularly priced at $80 . Your friend tells you that she saw the same coat for $ 80 in another store, but it was 20 % off plus an additional 10% off . Will you save money by going to the other store ? Explain why or why not .
Answer:
No
Step-by-step explanation:
Because if the coat is 20% with an additional 10% off that would equal 30% which is equal to the 30% off at the current store so they're both giving out the same deal
Answer:
No, because %30 is taking more off a higher number. Rather than only taking %20 off of it than the %10 is taking off an amount on a smaller amount resulting in it taking off less.
Step-by-step explanation:
$80 * 0.3 (%30) = $24
$80 - $24 = $56
$80 * 0.2 (%20) = $16
$80 - $16 = $64
$64 * 0.1 (%10) = $6.4
$64 - $6.4 = $57.6
