Answer:

The answer to your question is number 3.

Step-by-step explanation:

Data

slope = m = 2

Point = (3, 9)

Process

1.- Write the equation of the line in the form point-slope

y - y1 = m(x - x1)

2.- Identify the values of x1 and y1

x1 = 3 y1 = 9

3.- Substitution

y - 9 = 2(x - 3)

4.- Simplify

y - 9 = 2x - 6

y = 2x - 6 + 9

5.- Result

y = 2x + 3 slope y-intercept form

For passing Grade 8, you received a $150 gift card. You want to purchase a skateboard for $78.50 and a helmet for $32.00. a) Sal

Yuki888 [10]

Answer:

a) $14.37 sales tax

b) $25.13 left on gift card

Step-by-step explanation:

Purchases: 78.50 + 32.00 = 110.50

Sales tax: 13%:

1% of 110.50 = 1.1050

1.1050 x 13 = 14.365

rounded to 2 decimal places: $14.37

Total cost: 110.50 + 14.37 = $124.87

Gift card: 150.00 - 124.87 = 25.13

Answer:

Good luck :)

Step-by-step explanation:

S=2πrh+2πr ²

subtract 2πr ² from each side

S -2πr ² = 2πrh

divide by 2πr from each side

(S -2πr ² )/ 2πr = h
