Which graph models the solution set of 50x + 150y>1500?
hodyreva [135]

Answer:

see attached diagram

Step-by-step explanation:

First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.

When x=0, then 150y=1500, y=10.

When y=0, then 50x=1500, x=30.

Connect points (0,10) and (30,0) to get needed dashed line.

Then determine which region (semiplane) you have to choose. Note that origin's coordinates  (0,0)  do not satisfy the inequality 50x + 150y>1500, because

50\cdot 0+150\cdot 0=0

This means that origin lies outside the needed region, so you have to choose the semiplane that do not contain origin (see attached diagram).

Solve the problems using your graphing calculator. Round all parameter values to
Effectus [21]

Drawing a scatter plot for the given values on a graphing calculator, we have;

  • y = -0.19•x + 8.36

<h3>How can the function that best represents the data be found?</h3>

The values are;

Day; Running time

1; 8.2

2; 8.1

3; 7.5

4; 7.8

5; 7.4

6; 7.2

7; 7.1

Entering the above values in a graphing calculator, we have;

  • The slope of the line of best fit = -0.19
  • The x-intercept = 45

Therefore;

  • 0 = -0.19 × 45 + y-intercept

0 = -8.36 + y-intercept

  • y-intercept = 8.36

The equation found using the statistics function for scatter plot on a calculator is therefore;

  • y = -0.19•x + 8.36
