Answer:
B) {1000, 1100, 1200, 1300, 1400, 1500, 1600}
Step-by-step explanation:
Domain is the set of x values (input)
and
Range is the set of y values (output)
In this case, y = pay per month
so Range = {1000, 1100, 1200, 1300, 1400, 1500, 1600}
They will have to share 2.5 pounds of rice
Answer:
74.60=3x+2.60
74.60-2.60=72
72/3=24
x=24
the taxi ride was 24 miles
Since people read newspapers for a average of 364 minutes for a week, which is 7 days, you must divide 364 by 7. After you figure out how much they read per day multiply that by three to get your final result.
Answer:
B) y=3x+7.5
Step-by-step explanation:
The equation of the data in the table can be obtained by using any two points.
We will use points (3, 13) and (5,17)
<u>The slope - intercept form is: </u>
<u>We find the slope as:</u>
- m = (17-13)/(5-3) = 4/2 = 2
<u>The equation becomes:</u>
<u>To find the value of b, the y -intercept is:</u>
- 13 = 2*3 + b ⇒ b= 13 - 6 = 7
<u>So the equation is:</u>
<u />
<h3>Now let's compare this with the options</h3>
A) y = 2x + 8.5
- The slope is 2, and y- intercept is 8.5
- It has same slope and greater y-intercept
- Answer is <u>no</u>
B) y=3x+7.5
- The slope is 3, and y- intercept is 7.5
- It has greater slope and greater y-intercept
- Answer is <u>yes</u>
C) y=5x+6.5
- The slope is 5, and y- intercept is 7.5
- It has greater slope but smaller y-intercept
- Answer is <u>no</u>
D) y=10x+5.5
- The slope is 10, and y- intercept is 5.5
- It has greater slope but smaller y-intercept
- Answer is <u>no</u>
