Answer:

A.) 2x = y + 7

y = x + 6

The variable "x" would represent Jacob's score and the variable "y" would represent Paul's score in each equation. In the first equation, 2x would represent Jacob's score multiplied by 2, and 7 would represent the amount of points needed in order for Paul to have double Jacob's score. In the second equation, 6 would represent the amount of points needed in order for Jacob's score to be equal to Paul's score.

B.) They are both correct so Jacob's score is 13 points and Paul's is 19.

6 + 7 = 13 (the difference between scores in both equations)

6 would represent the amount that Paul is above Jacob's score and 7 would represent the amount that Paul would have to score to get two times Jacob's score. So, this shows that Paul would have 26 points if he had double the amount of Jacob's score and 26 ÷ 2 = 13.

Hope This Helps!

What is the arithmetic sequence in this problem . help plz

adell [148]

Answer:

a(n)=80*(9/10)^(n-1)

Step-by-step explanation:

I think u r confused

this sequence is geometric not arithmetic

HOw we know that ??

when we get a common difference that must Be equal

d=72-80=-8 not equal to d=64.8-72=-7.2

So it is not arithmetic

but when we get the common ratio that also must be equal

r=72/80=9/10 equal to r=64.8/72=9/10

So it is geometric

By using this equation:

a(n)=a*r^(n-1)

and we have a=80 , r=9/10

Then a(n)=80*(9/10)^(n-1)

I really hope this helps <3

A TV that usually sells for $192.74 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including

Mashutka [201]

Answer:

Step-by-step explanation:

If you are saving 25%, you are still paying 75%, right? So the cost of the TV with a discount of 25% is 192.74(.75) which is $144.56

That's the cost of the TV on sale. Now we need to find the sales tax amount, if the sales tax is .05 as a decimal. We are paying $144.56 for the TV, which is 100% of the cost. On top of that, we are paying another 5%. So altogether, for the TV, we are paying 105% of the TV. Therefore,

144.56(1.05) = $151.79

A car moving at a constant speed passed a timing device at t=0. After 9 seconds, the car has traveled 837 ft. Write a linear fu

diamong [38]

Answer:

at t=0 the car has moved 0 feet, also you know it has a constant speed so you get the points:

P1:(0,0) therefore you know b, the y-intercept=0

P2:(8,840)

insert P2 into y=mx+b

840=8m+0

840/8=m

105=m

so the result is:

y=105x=105t=f(t)=d
