I was just wandering if this was correct?

1. Your company is planning to spend no less than \$80,000 and no more than \$100,000 on a landscaping project, which will be used as a promotional park that promotes your toaster manufacturing company. Write an inequality with a variable that demonstrates how much money your company is willing to spend. (20% of grade)

80,000 ≤ y ≤ 100,000

2. In the promotional park your company has budgeted \$40,000 for some High Quality Astroturf and trees for a miniature golf course. The company plans on laying out 4,000 square feet of High Quality Astroturf, which costs \$5.50 per square foot. The trees that your company wants to plant on the course cost \$1313 each. Write out an inequality using the variable “t” for trees to show how many trees that you can plant. (20% of grade)

4,000(5.5) + 1313t<1=40,000
22,000+1313t < = 40,000
1313t < = 13.7
T < = 13 I can plant 13 trees because I cannot plant .7 trees

3.

a. Write an equation in the “y = mx + b” format for the canal that runs through the Toaster Company property. Solve for “m” and “b” in the “y = mx + b” formula. The canal crosses the x-axis at -16 and crosses the y-axis at 3. See the chart for a visual. (20% of grade)

X intercept is -16, the point is (-16,0)
Y intercept is 3, that is the b of the equation and the point (0,3)
Slope= (3,0)/(0-(-16))= 3/16
This makes the equation y= (3/16)x+3

b. Write an equation in the “y = mx + b” format for the Power Lines that runs through the Toaster Company property. Solve for “m” and “b” in the “y = mx + b” formula. The power lines cross the y-axis at 1 and cross the x-axis at 4. See the chart for a visual. (20% of grade)

y=4x+1

c. What is the slope of the equation for the power lines? (10% of grade)

16

d. What is the slope of the equation for the canal? (10% of grade)

• MAT/116 - ,

3 b) is not correct
you have 2 points (0,1) and (4,0)
the slope is (0-1)/4-0) = -1/4 , you had 4

equation: y = (-1/4)x + 1

c) slope of power line would be -1/4
d) slope of equation of canal is 3/16
