Lian is paid for SR 75 per hour. Using p for her pay and h for the hours of work, which function rule represents
Andru [333]

Answer:

The function p = 75h represents  this situation.

Step-by-step explanation:

We know the equation of linear equation in the slope-intercept form is

y = mx+b

where

m = rate of change = slope

b = y-intercept

  • Let 'h' be the number of hours
  • Let 'p' be the pay

Given that Lian is paid SR 75 per hour.

so the rate of change of slope = m = 75

As there is no initial condition, so b = 0

as

y = mx+b

Now, mapping the information data into the slope-intercept form

  • p = y
  • m = 75
  • h = x
  • b = 0

Thus, the equation becomes

p = 75h

Therefore, the function p = 75h represents  this situation.

VERIFICATION:

Given the equation

p = 75h

for h = 1

p = 75(1)

p = 75

Thus, Liam is paid SR 75 per hour.

Which expression can be used to convert 22 Australian dollars to US dollars?
STatiana [176]

Answer:

22 AUD × (1 USD)/(1.2 AUD)

Step-by-step explanation:

1.2 AUD = 1 USD

Divide both sides by 1.2 AUD.

(1.2 AUD)/(1.2 AUD) = (1 USD)/(1.2 AUD)

(1 USD)/(1.2 AUD) = 1

The conversion factor from AUD to USD is (1 USD)/(1.2 AUD)

Answer: 22 AUD × (1 USD)/(1.2 AUD)

I need help with this problem, i am confused and don't know what to do.​
klasskru [66]

Problems a through c are asking you what the values would be at those values.

What will the value of f(x) be at x=0? Let's look at the graph.

It seems at x=0, f(x)=0, meaning that f(0)=0

Let's do the same for the others.

At x=-3, f(-3)=2

At x=2, f(2)=-4

For the last question, it is giving us the f(x) value and asking us which x values would give us that.

At f(x)=3, x=-2.

*Note* this function is continuous to the right, meaning that there is another point where f(x)=3.

Hope this helps.

頑張って!

A chef needs to decorate cupcakes for a birthday party. If the chef places
dimaraw [331]

The possible number of cupcakes is less than or equal to 23

<h3>How to write inequality equation?</h3>

let

  • k = possible number of cupcakes
  1. Number of strawberry slices = 46
  • Number if strawberry slices on each cupcake = 2

The inequality:

2k ≤ 46

divide both sides by 2

k ≤ 46 / 2

k ≤ 23

Therefore, the possible number of cupcakes is less than or equal to 23
