Answer: y = -1.5x

Step-by-step explanation:

Use y2-y1 over x2-x1.

-6-3/4+2=-9/6

-9/6=-1.5

Plug in either point on the graph as x and y (I used (-2,3))

3=(-1.5)(-2)+b

3=3+b

b=0

Your equation is y = -1.5x+0

(You don't typically write the 0)

Brums [2.3K]

Answer:

Q:4A ($30) * 0.85 = $25.50

Q:4B ($18) * 0.85 = $15.30

Q:4C ($24.80) * 0.85 = $21.08

Q5:

(For six pack): $2.10 (each) * 8 = $16.80

(For eight pack): 3.12 (each) * 6 = $18.72

8 of the 6 packs would be the better deal.

Q6 (A): Elena is 142.24 cm tall.

(Formula is multiply the inches by 2.54. So, 56 times 2.54 is 142.24)

Q6 (B): Elena is 1.4224 meters tall.

(Formula is divide inches by 39.37. So, 56 divided by 39.37 is 1.4224)

*Hana purchased 2 pairs of pants for $26.59 each and a coat for $49. She used a coupon that saved her $10. The sales tax for the

Verizon [17]

Answer:

$100.02

Step-by-step explanation:

*Sales tax is always applied after the discount/coupon

1. Find how much Hana had spent on pants. Since she had bought 2 pairs of pants, and they are $26.59 each, we would have to multiply 26.59 by 2. So,

26.59 times 2 is 53.18.

Hana spent $53.18 on pants

2. Find how much Hana had spent on a coat. Since she had bought 1 coat, and they are $49.00 each, we would have to multiply 49.00 by 1. So,

49.00 times 1 is 49.

Hanna spent $49 on coats

3. Find how much Hana spent on clothes. Since she spent $53.18 on pants and $49 on coats, we would have to add 53.18 and 49. So,

53.18+49=102.18

Hanna spent $102.18 on clothes

4. Find how much Hana "spent" after using the coupon. Since the problem says the coupon helps Hana save $10, we need to subtract 10 from 102.18(the total amount of money Hana spent on clothes before using the coupon). So,

102.18-10=92.18

Hanna "spent" $92.18 on clothes after using the coupon

5. Find how much was the total purchase. Sales Tax is the amount of money that needs to be added to the price. Since the price is $92.18 and the sales tax is $7.84, we need to add 7.84 to 92.18. So,

7.84+92.18=100.02

The total purchase is $100.02
