Answer:

y = 5x - 7

Step-by-step explanation:

y = mx + c

y = 5x + c

to find c, input given coordinates

8 = 5 x 3 + c

8 = 15 + c

-c = 15 - 8

-c = 7

c = -7

put that all together and you get:

y = 5x - 7

The function f is defined by the following rule

Oxana [17]

Answer:

The answer to your question is given below.

Step-by-step explanation:

1. f(x) = 5x + 1

x = – 5

f(x) = 5x + 1

f(–5) = 5(–5) + 1

f(–5) = –25 + 1

f(–5) = –24

2. f(x) = 5x + 1

x = – 1

f(x) = 5x + 1

f(–1) = 5(–1) + 1

f(–1) = –5 + 1

f(–1) = – 4

3. f(x) = 5x + 1

x = 1

f(x) = 5x + 1

f(1) = 5(1) + 1

f(1) = 5 + 1

f(1) = 6

4. f(x) = 5x + 1

x = 2

f(x) = 5x + 1

f(2) = 5(2) + 1

f(2) = 10 + 1

f(2) = 11

5. f(x) = 5x + 1

x = 2

f(x) = 5x + 1

f(3) = 5(3) + 1

f(3) = 15 + 1

f(3) = 16

Summary

x >>>>>>>> f(x)

–5 >>>>>> – 24

–1 >>>>>> – 4

1 >>>>>>>> 6

2 >>>>>>> 11

3 >>>>>>> 16

A Construction contractor used the equation 11.52 = (1.44)8 to calculate how much 8 boxes of nails would cost him . How much wou

k0ka [10]

Answer:

The 2 boxes of nails will cost him $ 2.88.

Step-by-step explanation:

Cost of a given substance is the amount of money needed to acquire it. The total cost involved in the purchase of a given number of units is equal to the cost of one unit multiplied by the total number of units.

Total cost = Cost of 1 unit × Total number of units ....equation 1

Given: Boxes of nails to be bought = 8

Price of 2 boxes of nails = ?

Assuming the money to be in dollars ($).

The given equation used to calculate the cost of 8 units or boxes of nails:

11.52 = (1.44)8 ....equation 2

By comparing equations (1) and (2), we get

The cost of 1 box of nails = $ 1.44

and the total cost of 8 boxes of nails = $ 11.52

∴ The total cost of 2 boxes of nails = cost of 1 box of nails × 2 = $ 1.44 × 2 = $ 2.88

Therefore, the 2 boxes of nails will cost him $ 2.88.

Can you please help me I need help with this question it’s for my test

kodGreya [7K]

Answer:

y=3

Step-by-step explanation:

Assuming this is an enlargement where EFGH is enlarged to ABCD then the former is the object and the latter is the image. If so then

scale factor(k) of the enlargement=image length/corresponding object length

k=3/2

Therefore, y=4.5/k

y=4.5/(3/2)

y=3

If we take the assumption another way and say ABCD is reduced to EFGH then the former is the object and the latter is the image.

In that case,

k=⅔

y=4.5×k

y=3

In either case y=3units
