Step-by-step explanation:
Answer:
D) Owen’s function has a greater slope, and Rose’s function has a greater y-intercept
Step-by-step explanation:
slope-intercept form of linear equation: y = mx + b
(where m is the slope and b is the y-intercept)
Slope = change in y ÷ change in x
y-intercept is where the line crosses the y-axis
Owen: y = (3/4)x + 1
Rose: y = (2/3)x + 2
Owen's function has a greater slope, since 3/4 > 2/3
Rose's function has a greater y-intercept, since 2 > 1
To find the cost of each item, you will create an equation in terms of the t-shirt.
Each item is related to the price of the t-shirt.
SWEATPANTS + SWEATSHIRT + TEE SHIRT = TOTAL COST
(2t - 5.50) + (t + 8) + t = $76.50
4t + 2.50 = 76.50
- 2.50 -2.50
<u>4t</u> = <u>74</u>
4 4
t = $18.50
The tee shirt is $18.50.
The sweatpants are 2 x $18.50 - 5.5 = $31.50
The sweatshirt is $18.50 + 8 = $26.50
