Step-by-step explanation:
Write an equation of the line that passes through point P and is parallel to the line with the given equation. P(3,5); y=2x-6
Answer:
y = -(5/2)x + 3 is a line perpendicular to y = (2/5)x + 2. This line is also perpendicular to y = (2/5)x + 9 because it has the same slope.
Step-by-step explanation:
A) So the line you are given is written in slope intercept form y = mx + b meaning that the slope of the line is m = 2/5 and the intercept b = 9 (so the line hits the y axis at 0,9). A line that is parallel has to have the same slope so we know our m is the same. So we have y = (2/5)x + b. We need b. It passes (0, 2) since the x coordinate is 0 you know the y intercept is 2 but you can verify this using the point slope formula:
y - y1 = m(x - x1) plug in values
y - 2 = (2/5)(x - 0) now simplify
y - 2 = (2.5)x last solve
y = (2/5)x + 2 see how when the x coordinate is 0 you can automatically use the point slope intercept formula? Neato!
B) Now we want a line perpendicular to y = (2/5)x + 2 and that passes through 0,3. What are the properties of a line perpendicular to a line of the form y = mx + b and passes through (0, 3)? We know that the slope of this new line will be the reciprocal and have the opposite sign of m. So the new slope we will call it mnew = -(1/m) so plug in for m and you get mnew = -(1/[2/5]) if you simplify you get that the mnew = -(5/2). So we have half of our equation for the perpendicular: y = -(5/2)x + b. If you look at (0, 3) you see that the y intercept is 3 so b = 3. So:
The equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, we need to find the equation of a line passing through the point (3, 5) and is parallel to y = 2x-6,
Comparing the given equation with the general equation of line y = mx+c
m = 2 (the slope)
We know that the two parallel lines have equal slope.
Therefore, the required equation is =
y = 2x+c
To find the value of c, put x = 3 and y = 5,
5 = 2(3) + c
c = -1
Therefore,
The required equation is =
y = 2x-1
Hence, the equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

How many miles did Jayne travel in 4 hours
Answer:

Step-by-step explanation:
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
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 :)

Step-by-step explanation:

Answer:
6 2/3 or 20/3 or 6.6667
Step-by-step explanation:
Since the figures are similar, you can find x through comparing ratios. To get from 9 to 4, multiply 9 by 4/9. To find x, you must then multiply 15 by 4/9.
15 x 4/9 = 6 2/3 or 20/3 or 6.6667

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

Write an equation in slope-intercept form for the line with slope 6 and y-intercept -9.
Answer:
y=6x-6
Step-by-step explanation:
The slope equation is: y=mx+b
Keep in mind that m= slope and b= y-intercept
Since this problem gives us both of the things needed to complete the equation, we just need to plug it in.
m, (slope) = 6
b, (y-intercept) = -9
y= 6x-6
