y = negative x + 9
y = negative x minus 3
y = x + 9
y = x minus 3
Answer:
Y = negative x + 9
Step-by-step explanation:
Find the equation of the line for side S-
m= 4-1/1-4 = 3/-3 = -1
The Gradient is -1
Since parallel lines share the same gradient, it should be either of the first two options.
We can see side Q shares the same gradient: 3-6/6-3= -1
Find the equation of the line of side Q-
y-y1= m(x-x1)
y-6= -1(x-3)
y-6=-x+3

A garden table and a bench cost $814 combined. The garden table costs $86 less than the bench. What is the cost of the bench?
Answer:
The Bench is 450 and the Garden table is 364
Step-by-step explanation:
Total of $814 substrate our difference of $86
so 814-86= 728 divide this by the amount of furniture purchased (2)
2/ 728= 364. Add on our difference of 86 to get our larger amount of 450.
Answer:
The bench cost $364
Step-by-step explanation:
Hey there,
Before starting, you want two separate variables to represent both the table and the bench.
Let's do this...
Garden table: x
Bench: y
*Note the variables don't have to be x and y, they just have to be two different variables, I just chose x and y. Any letter works as long as they're different.
We then know that the garden table PLUS the bench had a total cost of $814.
Going back to our variables, we could represent this system by saying...
x + y = 814
(remember x is the garden table and y is the bench)
We also know that the garden table costs $86 LESS than the bench.
Going back to our variables, we could represent this by saying...
x - 86 = y
(x - 86 is basically saying that the garden table minus $86 equals the cost of the bench)
Just by looking at this, we know that y is equal to x - 86.
Here's what you have to do...
Plug in y for the first equation...
x - 86 = y
x + ( x - 86 ) = 814
Now, solve...
2x - 86 = 814
Add 86 on both sides...
2x = 900
divide by two on both sides...
x = 450
We now know that the garden table costs $450. But how do we find the cost of the bench? Plug in x back into the original equation...
x + y = 814
(450) + y = 814
subtract 450 on both sides...
You get y = 364
The bench has a total cost of $364
I really hope this helped :)

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.
You would like to have $41,000 in 5 years for the down payment on a new house
following college graduation by making deposits at the end of every three months in
an annuity that pays 4.25% compounded quarterly. How much should you deposit at
the end of every three months? How much of the $41,000 comes from deposits and
how much comes from interest?
Answer:
a. You are looking for an annuity that will give $41,000 in 5 years with a quarterly compounding rate of 4.25%.
Convert periods and interest to quarterly rate.
Period = 5 * 4 = 20 quarters
Interest = 4.25 / 4 = 1.0625%
41,000 = Annuity * ( [ 1 + i ] ^n - 1 )/i
41,000 = Annuity * ( [ 1 + 1.0625%]²⁰ - 1) / 1.0625%
41,000 = Annuity * 22.1534596596
Annuity = 41,000 / 22.1534596596
= $1,851
b. There were 20 payments of $1,851 made which totals:
= 1,851 * 20
Cash from deposits = $37,020
Cash from interest = 41,000 - 37,020 = $3,980
Shaneen has $30 to spend on CDs that each cost $10. She wants to calculate n, the number of CDs she can buy with her $30. Which inequality represents the maximum number of CDs she can buy?
Answer:
[tex]10n \le 30[/tex]
[tex]n \le 3[/tex]
Step-by-step explanation:
Given
[tex]Total = \$30[/tex]
[tex]Cost (each) = \$10[/tex]
Required
Determine the inequality
Assume she wants to buy n CDs.
If 1 CD costs $10, then n CDs costs 10n.
So, the inequality is:
[tex]10n \le 30[/tex]
We used [tex]\le[/tex] because the amount she wants to spend cannot exceed 30
Divide both sides by 10, to solve for n
[tex]n \le 3[/tex]

What is the distance between the two points at(-3,8) and(-3,-7)
Answer:
[tex]\boxed {\boxed {\sf 15}}[/tex]
Step-by-step explanation:
Distance is calculated using this formula:
[tex]d=\sqrt {(x_2-x_2)^2+(y_2-y_1)^2[/tex]
where (x₁, y₁) and (x₂, y₂) are the points. We are given (-3,8) and (-3,7). Therefore;
[tex]x_1= -3 \\y_1= 8 \\x_2= -3 \\y_2= -7[/tex]
Substitute the values into the formula.
[tex]d= \sqrt {(-3--3)^2+(-7-8)^2[/tex]
Solve inside the parentheses.
-3 - - 3= -3+3= 0 -7 - 8 = -15[tex]d= \sqrt {(0)^2+(-15)^2[/tex]
Solve the exponents.
0²=0*0= 0 -15²= -15*-15=225[tex]d=\sqrt {0+225[/tex]
[tex]d=\sqrt {225[/tex][tex]d= \pm 15[/tex]
A negative number for distance doesn't make sense, so the distance must be 15.

Learn by DoingHere are the directions, grading rubric, and definition of high-quality feedback for the Learn by Doing discussion board exercises.ContextStudents researching backpack weights gathered data from 45 elementary school children in the 3rd and 5th grades. The variable is "percent of body weight carried in the school backpack." So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 ÷ 60 = 0.15 = 15%). The American Chiropractic Association (ACA) recommends that children carry no more than 10% of their body weight.PromptWhen we analyze backpack weight as a percentage of body weight, how do 3rd and 5th graders compare?

State whether the triangles are similar. If so, write a similarity statement and the postulate or theorem you used. The diagram is not drawn to scale.
Givn : OK = 3, OJ = 30, KN = 1, JM = 3
ON=OK+KN=3+1=4
OM=OJ+JM=30+10=40
In triangles OKJ & ONM,
OKOJ=330=110
ONOM=440=110
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means KJNM=110 or the two sides are parallel.
Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.
Two sides in each triangle that are proportional to each other, and a corresponding included angle in both triangles that are congruent, both triangles are similar.
The similarity statement is: [tex]\triangle NOM \sim \triangle KOJ[/tex]Theorem: Side-Angle-Side Similarity Theorem (SAS)Recall:
Two triangles can be proven to be similar by the SAS Similarity Theorem, if they both have two pairs of corresponding side lengths that are proportional to each other and also have a corresponding included angle that is congruent to each other.
Using the image given, let's determine if two of the given side lengths of each triangle are proportional to each other.
Given:
OJ = 30OM = 30 + 10 = 40OK = 3ON = 3 + 1 = 4Thus:[tex]\frac{OM}{OJ} = \frac{ON}{OK}[/tex]
Substitute[tex]\frac{40}{30} = \frac{4}{3}[/tex] (proportional)
Also, <NOM and <KOJ are congruent to each other (included angles).
Therefore, since we have two sides in each triangle that are proportional to each other, and a corresponding included angle in both triangles that are congruent, both triangles are similar.
The similarity statement is: [tex]\triangle NOM \sim \triangle KOJ[/tex]
Theorem: Side-Angle-Side Similarity Theorem (SAS)

Alexandra needs to rent a car while on vacation. The rental company charges $17.95, plus 15 cents for each mile driven. If Alexandra only has $50 to spend on the car rental, what is the maximum number of miles she can drive?
Answer: 213 2/3 miles
Step-by-step explanation:
first we need to set up an equation to solve
let your equation be in y=mx+b form since we are using a rate
Since this is a word problem, dissect it and match each part with a variable in the slope-intercept equation
y = Budget
m = rate
x = how many miles she can go -- the unknown variable
b = the initial fee
Your equation should be: 50 = 0.15x + 17.95
We want to soIve for x now so first get rid of the coefficient not attached to it
To do this, you do the inverse function of addition, which is subtraction
Subtract 17.95 from both sides
Your new equation will be: 32.05 = 0.15x
0.15 is still attached to x, so we want to do the inverse function of multiplication, which is division
divide both sides by 0.15
Your final answer: 213 2/3 miles
.Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.

How many miles did Jayne travel in 4 hours
Answer:
20
Step-by-step explanation:
Question Help In 2005, it took 20.29 currency units to equal the value of 1 currency unit in 1917. In 1990, it took only 13.10 currency units to equal the value of 1 currency unit in 1917 The amount it takes to equal the value of 1 currency unit in 1917 can be estimated by the linear function V given by V(x) = 0.4925x + 13.7485 where x is the number of years since 1990 Thus, V(11) gives the amount it took in 2001 to equal the value of 1 currency unit in 1917. Complete parts (a) and (b) below a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
Answer:
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Step-by-step explanation:
The value needed to equal the value of 1 currency unit in 1917, in x years after 1990, is given by:
[tex]V(x) = 0.4925x + 13.7485[/tex]
a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
2011 is 2011 - 1990 = 21 years after 1990, so we have to find V(21).
[tex]V(21) = 0.4925*21 + 13.7485 = 24.091[/tex]
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
2019 - 1990 = 29, so we also to find V(29).
[tex]V(29) = 0.4925*29 + 13.7485 = 28.031[/tex]
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
