Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.

We would solve this using direct proportion.

y = kx.

12.15 = 11.25k

k = 12.15 / 11.25

k = 1.08

Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.

y = kx.

59.13 = 54.75k

k = 59.13 / 54.75

k = 1.08

The equation that models the relationship will be:

y = 1.08x

noname [10]
Hmm, so they seem to be increaeing by powers of 5
10=2 times 5
25=5 times 5
35=7 times 5
60=12 times 5

so maybe it is
nth term=5(n+2) or 5n+10
lets try it
0th term
5(0)+10
0+10=10
corrrect

3rd term
5(3)+10
15+10
25
correct



so the function is
f(x)=5(x+2)

The total cost of 2 novels and 4 fiction books is $84. Each novel costs $6 more than each fiction book. What is the total cost o
zhuklara [117]

Answer:

$30

Step-by-step explanation:

Let,

  x - fiction book

  x + $6 - novel

EQUATION:

  4(x) + 2(x + $6) = $84

  6x + $12 = $84

  6x = $84 - $12

  6x = $72

  x = $12

SUBSTITUTE:

    novel = $12

    fiction = $18

TOTAL COST OF NOVEL AND FICTION

$18 + $12 = $30

Help please alegra2

A = 1/2bh...multiply both sides by 2
2A = bh...divide both sides by b
(2A)/b = h

s = 1/2gt^2...multiply both sides by 2
2s = gt^2...divide both sides by t^2
(2s) / (t^2) = g

H = vt - 5t^2...add 5t^2 to both sides
H + 5t^2 = vt...divide both sides by t
(H + 5t^2) / t = v
