Let r = ⟨5, –1⟩, s = ⟨6, 0⟩, and t = ⟨–1, –3⟩. Aaron incorrectly determined 2r + 4s – 7t as ⟨41, –23⟩. Review his calculations.
2r + 4s – 7t
2⟨5, –1⟩ + 4⟨6, 0⟩ – 7⟨–1, –3⟩
⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩
⟨41, –23⟩
What mistake did Aaron make?
He added ⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩ incorrectly.
He should have subtracted ⟨7, –21⟩ rather than add.
He did not correctly distribute 4 to both components of s.
He did not correctly distribute the negative when subtracting 7t.

Identify the function shown in this graph.
Answer:
Step-by-step explanation:
Answer:
C. y = -2x - 1
Step-by-step explanation:
y = mx + b
The slope is going down so that means that the m will be negative.
We are left with two choices:
y = -2x - 1
y = -2x + 1
Check the graph again to find what point does the line intersect the vertical line (y-axis). That hits in (0, -1) or -1.
So the only answer applicable is option C.

The price of a new SMART television was reduced from $250 to $200. By what percentage was the price of the television reduced?
20%
25%
5%
50%
Answer:
20%
Step-by-step explanation:
if the 100% of the price is $250 and the discount is $50 then to find what percent $50 we multiply 100 by 50 then divide it with 250
100 × 50 ÷ 250 = 20

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answer:
x = 3
y = -1
Step-by-step explanation:
in this system, we are given that y = x - 4
this means that we can take the other equation and replace y with x - 4:
so 2x - 3y=9 turns into
2x -3 (x - 4) = 9
distribute -3 to x and -4:
2x - 3x + 12 = 9
add like terms and subtract 12 from both sides
-x = -3
divide both sides by -1 to get rid of the negative on x:
x = 3
now we have the value of x, so we can replace the x in y = x - 4 with the value we just got
so y = x- 4 turns into
y = (3) - 4
solve and you get
y = -1

2. In Parallelogram TRIK, what is the mzt?
R
T
5x°
2(x + 30°
K
I
I
Answer:
[tex]T = 100[/tex]
Step-by-step explanation:
See attachment for parallelogram TRIK
Given
[tex]T = 5x[/tex]
[tex]I = 2(x + 30)[/tex]
Required
Determine T
Because T and I are opposite angles of the parallelogram, then they are congruent.
i.e.
[tex]T = I[/tex]
Substitute values for T and I
[tex]5x = 2(x + 30)[/tex]
Open bracket
[tex]5x = 2x + 60[/tex]
Collect Like Terms
[tex]5x - 2x = 60[/tex]
[tex]3x = 60[/tex]
Solve for x
[tex]x = \frac{60}{3}[/tex]
[tex]x =20[/tex]
Recall that:
[tex]T = 5x[/tex]
[tex]T = 5 * 20[/tex]
[tex]T = 100[/tex]
What fraction of the students finished in less than 20 minutes
The fraction of the students finished in less than 20 minutes is 2/3
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given the table of the time it took a group of students to complete a puzzle.
Here we can see that total frequency is 24, and the frequency that finished in less than 20 min is 16,
This means the frequency that depends on the number of students.
Therefore, 16/24 = 2/3

David is buying a cheese wheel priced at $ 14 $14dollar sign, 14 before tax. The store charges 8 % 8%8, percent sales tax. What is the total price, including tax, David pays for the cheese wheel? $
Answer:
$15.12
Step-by-step explanation:
{10 * 0.08 = 0.8
4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)
[0.8 + 0.32 = 1.12]
14 + 1.12 = 15.12
David is buying a cheese wheel priced at $14 on 8% sales tax.
David's pays for the cheese wheel is $15.12 .
Given:
Before-tax, the price of cheese wheel = $ 14
Sales tax on cheese wheel = 8%
Sales tax is 8% of $14
[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]
So, the sales tax on the cheese wheel is $1.12
The total price of the cheese wheel, including tax = $ 14 + $1.12 = $15.12
Therefore, David's pays for the cheese wheel is $15.12 .
