Using the rise over run strategy, you can get this answer by...
1. Look at the line and graph 2 points. ( 1 , 1 ) & ( 2 , 2 ).
2. Do the rise over run thing. ( how am I going to get from 1 point to the other.)
You get to it by rising 1 and running 1. The pattern is self explanatory.
3. Divide rise over run and the quotient is your answer
1 divided by 1 is 1.

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answers
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

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.

Answers
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.

20%
25%
5%
50%
Answers
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

Recall that all angles in a triangle sum up to 180°, therefore:
(9x + 3) + (5x - 2) + (11x - 21) = 180
Combine like terms:
9x + 5x + 11x + 3 - 2 - 21 = 180
25x -20 = 180
Add 20 to both sides:
25x = 200
Divide both sides by 25:
x = 8°
Answer:
Step-by-step explanation:
we know that the sum of the angles in a triangle is 180
(5x-2)+(9x+3)+(11x-21)=180
=5x-2+9x+3+11x-21=180
25x=180+20
25x=200

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? $
Answers
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 .
