The standard form:

$Ax+By=C$

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have m = 3 and b = -5.

Substitute:

$y=3x-5$ subtract 3x from both sides

$-3x+y=-5$ change the signs

$3x-y=5$

Need help with geometric sequences <br> 30 points

NeTakaya

Answer:

$a_{n}$ = 6 $(5)^{n-1}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = 6 and r = 30 ÷ 6 = 5, thus

$a_{n}$ = 6 $(5)^{n-1}$

At Best Buy they have a 60" TV that sells for $1250 and is on sale for 15% off. If the sales tax is 6.5%, what is the final cost

NNADVOKAT [17]

Answer:

Step-by-step explanation:

The sale price = Initial Cost - 15% of the initial Cost

The sale price = 1250 - 15/100 * 1250

The sale price = 1250 - 187.5

The Sale Price = 1062.5

Now you add on the sales tax

Cost with Sales Tax = 1062.50 + 6.5/100 * 1063

Cost with Sales Tax = 1062.50 + 69.06

Cost with Sales Tax = 1131.56 dollars.

For 30 people how many packages of hots dos and buns have to buy

Leona [35]

Hot dogs are sold in packs of 10. 30 divided by 10 equals 3. (30/10=3)
Buns are sold in packs of 8. 30 divided by 8 equals 3.75. (30/8=3.75) but we must round to 4 since we can’t buy 75% of a pack of buns.

3 packs of hotdogs and 4 packs of buns
