Which linear inequality is represented by the graph?
jarptica [38.1K]

Answer: y > 2x + 1

Step-by-step explanation:

In the graph first, we can see two things:

The line is not solid (so the values in the line are not included), and the shaded part is above, so we will be using the symbol:

y > f(x)

Now, in the line we can see that when x = 0, y = 1.

So the linear equation must be something like:

f(x) = a*x + 1

The only one that has an y-intercept equal to 1 is y > 2x + 1

Mai is filling her fish tank. Water flows into the tank at a constant rate. Complete the table and answer the question below.
kvasek [131]

Answer:

r = 1.6

Step-by-step explanation:

Given

x   -----   y

0.5. --- 0.8

1. --- 1.6

3.--- 4.8

25. --- 40

Required

Determine the constant of proportionality

This can be calculated using the following formula:

y = rx ; Where r is the constant of proportionality;

Solve for r

r = \frac{y}{x}

When x = 0.5; y = 0.8

r = \frac{0.8}{0.5}

r = 1.6

When x =  1; y =1.6

r = \frac{1.6}{1}

r = 1.6

When x =  3; y = 4.8

r = \frac{4.8}{3}

r = 1.6

When x =  25; y = 40

r = \frac{40}{25}

r = 1.6

Notice that the value of r is constant throughout;

Hence:

r = 1.6

lisabon 2012 [21]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

The original amount of money on the gift card was $45. After buying 8 cups of coffee, the remaining balance was $25.

<u>First, we need to calculate the unitary value of each cup of coffee:</u>

Unitary cost= 20/8= $2.5

<u>Now, we can structure the remaining balance formula (A):</u>

A= 45 - 2.5x

x= cup of coffee

<u>After 2 cups:</u>

A= 45 - 2.5*2

A= 40
