Y = - 7/6x + 1 Use the slope-intercept form to find the slope and y-intercept.

Answers

Answer:

slope = - (7)/(6) , y- intercept = 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given the line with equation

y = - (7)/(6) x + 1 ← in slope- intercept form

with slope m = - (7)/(6) and y- intercept c = 1

Answer & Step-by-step Explanation

We're given the following equation to work with.

-\!\!\!-\!\!\!-\!\!\!\! > \qquad\boldsymbol{\sf{y=-\cfrac{7}{6}x+1}}

We need to find the slope and the y-intercept.

The slope is the number in front of x, and the y-intercept is the constant term.

Therefore,

Note: This way of finding the slope only works for slope-intercept form. Slope-intercept is \sf{y=mx+b} where m is the slope and b is the y-intercept.

You need to put your reindeer, Rudy, Ezekiel, Gloopin, Bloopin, and Prancer, in a single-file line to pull your sleigh. However, Bloopin and Rudy are fighting, so you have to keep them apart, or they won't fly. How many ways can you arrange your reindeer?

Answers

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.

If Bloopin and Rudy are fighting, the reindeer do not fight, there are 72 ways that you can arrange your reindeer.

What are permutations?

The different arrangements which can be made out of a given number of objects by taking out some or all at a time are called permutations.

If Bloopin and Rudy are fighting, the reindeer do not fight,

then there are 5! = 120 ways

Out of these, Bloopin and Rudy are together in 4! = 24 times.  

Similarly, Rudy and Bloopin will be together 4! = 24 times.  

So the number of ways they are not together

120-24-24 = 72 ways.

Sally needs to have some drywall and insulation work done in her house. She has received a quote from a professional drywall contractor to complete her repairs for $1,200. Her neighbor Steve says he can complete the same job for $800. Sally could use a credit card to pay the contractor, but Steve can only accept cash. Sally’s credit card has a 14% APR for credit purchases and a 32% interest rate for cash advances. Expecting to pay $50 of the principle plus appropriate interest each month, Sally estimates that it would take her 24 months to pay off the contractor balance and 16 months to pay off the cash advance balance. In the end, would it be cheaper for Sally to hire the contractor or her neighbor to complete the repairs?

Answers

Answer:

Sally can chose Steve to work with.

Step-by-step explanation:

We will calculate EMI for both the contractor and Steve.

Contractor:

EMI formula = (p*r*(1+r)^(n) )/((1+r)^(n)-1 )

p = 1200

r = 14/12/100=0.0116

n = 24

Putting values in formula we get,

(1200*0.0116*(1.0116)^(24) )/((1.0116)^(24)-1 )

= $57.62

So, for $1200 at 14% for 24 months, Sally would have to pay $57.62 per month, or 57.62*24 = $1382.88 after 24 months.

Steve:

Similarly putting these values : (p=800, r=32/12/100= 0.0266 and n=16) in above formula we get, $62.08 per month or 62.08*16= $993.28 after 16 months.

Hence, even with the higher interest rate, Sally would pay:

1382.88-993.28 = $389.60 less if she chooses to work with Steve.

Though the monthly payments are almost same for the given timelines, still Sally can chose Steve.
It said the correct answer was the contractor
