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
7 is the only number that goes into all of em
Answer:

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:
; Where r is the constant of proportionality;
Solve for r

When x = 0.5; y = 0.8


When x = 1; y =1.6


When x = 3; y = 4.8


When x = 25; y = 40


Notice that the value of r is constant throughout;
Hence:

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
