Can someone help me with these questions? I'm really lost.

1. Judy took $30 with her to spend on popcorn and drinks for herself and her friends at the movie theater. The price for each bag of popcorn was $5. The price of each drink was half the price of a bag of popcorn.
(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of bags of popcorn and the other axis to represent the number of drinks.
(b) Explain your graph.

2. Graph the piecewise function.
f(x) = { 3x - 5 if x ≤ - 1 / -2x + 3 if -1 < x < 4 / 2 if x ≥ 4

3. Graph the step function over the interval -2 ≤ x ≤ 2.
f(x) = { x+ 3}

Answers

Answer 1

Answer:

Step-by-step explanation:

On the x axis have popcorn going up in 5s and up to the value 30 and on the y axis have drinks going up in 2.5s to the value 15.

The graph should look like similar to an 'exponential graph' because for every popcorn you buy, the drink will be half the price

Its probably late but, I hope this helped!!!.

Answer 2

Answer:

here is the graph!

Step-by-step explanation:

My graph represents the number of drinks and bags of popcorn that Judy will be able to purchase with her $30. For every two drinks Judy buy’s, she would have to buy one less popcorn.

A person hikes 4 miles in 2.5 hours. Find the unit rate in miles per hour.

Answers

Answer:

60 miles per hour

Since d=rt, r = d/t = 420 miles/7 hours = 60 miles per hour

Step-by-step explanation:

Answer:

1.6 miles per hour

Step-by-step explanation:

Step one:

The unit rate is the number of miles in 1 hour

given

distance= 4 miles

time= 2.5 hours

so if he hike 4 miles in 2.5 hours

then he will hike      x mile in 1 hour

cross multiply we have

x=4/2.5

x=1.6 miles per hours

Therefore the unit rate is 1.6 miles per hour

How many degrees is angle y

Answers

Answer:

y = 39°

Steps:

w = 180 - (85+42) = 180 - 127 = 53°

y = 180 - (88+w)

y = 180 - (88+53)

y = 180 - 141

y = 39°

Answer:

y = 39

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of both triangles , then

x = 42 + 85 = 127

and

y + 88 = 127 ( subtract 88 from both sides )

y = 39

D) 75.4 cm

Answers

Answer:

B. 18.8cm

Step-by-step explanation:

Circumference = π x Diameter

The given diameter here is 6cm and we need to use 3.14 for π so:

Circumference = 3.14 x 6

Circumference = 18.84 = 18.8 (1.d.p)

Therefore B is correct.
