Mathematics

EastWind [94]3 years ago

Answer:

Option c and d are correct

Step-by-step explanation:

The pair is ordered in this way: (x,y)

To get y you have to replace the different number of x in the equation

For example,  

In the first pair x is 2 and y= 14

To x=2

y=-5x+4

y=-5*2+4

y=-10+4

y=-6

To x=5

y=-5x+4

y=-5*5+4

y=-25+4

y=-21 (option d)

To x=-3

y=-5x+4

y=-5*-3+4

y=15+4

y=19(option c)

-3,6,-9,12,-15 which of the following represents the general term for the sequence give?
Mademuasel [1]

The general term for the sequence a_{n}=(-1)^{n} 3 n

<h3><u>Solution:</u></h3>

Given sequence is -3, 6, -9, 12, -15

We have to find the general term of sequence

The terms in the sequence are found out by using the recursive definition:

a_{n}=(-1)^{n} 3 n

Let us use this definition to find out the terms and check if it matches our given sequence

\begin{array}{l}{\text { For } n=1:-(-1)^{n} 3 n=(-1)^{1} \times 3 \times 1=-3} \\\\ {\text { For } n=2:-(-1)^{n} 3 n=(-1)^{2} \times 3 \times 2=1 \times 6=6} \\\\ {\text { For } n=3:-(-1)^{n} 3 n=(-1)^{3} \times 3 \times 3=-1 \times 9=-9} \\\\ {\text { For } n=4:-(-1)^{n} 3 n=(-1)^{4} \times 3 \times 4=1 \times 12=12} \\\\ {\text { For } n=5:-(-1)^{n} 3 n=(-1)^{5} \times 3 \times 5=-1 \times 15=-15}\end{array}

Thus the general term is given by a_{n}=(-1)^{n} 3 n

Please answer #6 for me!
sdas [7]
Ok s we know the total cost is $320 so if the cost for the supplies is $70 the n we will subtract 70 from 320 leaving us with $250. The jobs is 5 hours so we will divide 250 by 5 and get 50 so the total cost per hour is        $50
hope this helps!

When is a long-term purchase on a credit card better than taking out a loan?​
skad [1K]

Long-term purchase on a credit card better than taking out a loan when interest rate is 0% or very lower than loan, or any other benefits

<h3><u>Explanation:</u></h3>

We can use a credit card for long term purchases if there is a 0% interest rate on purchase is allowing you to pay off your shopping with no additional cost for an introductory period. Or some of the credit cards may offer interest-free purchases for 3 to 6 months others can run for as long as 12 to 14 months. An interest-free period could be considered long-term if it lasts between 12 and 14 months or more.

We could benefit from one of these cards if you are making a large purchase and need more breathing room to pay it off without any interest. This is especially useful if you have a high spending period such as an overseas holiday coming up.
