Answer:
y = -6x + 2
Step-by-step explanation:
Slope intercept form: y = mx + b
m is the slope
b is the y-intercept
The line pictured goes down 6 for each 1 it moves to the right, slope is rise over run, in this case, -6/1 or just -6
The y-intercept is the point that the function crosses the y-axis, in this case 2
Plug those in to get:
y = -6x + 2
Ngl I think it’s 20 because 15 is 5x3 but 60 divided by 3=20 lmk if I’m wrong
Answer:
9 3/4 cups of sugar
Step-by-step explanation:
Answer:27 pieces were sold at the original price.
63 pieces were sold at the new price
Step-by-step explanation:
Let x represent the number of pieces of pottery that was sold at the original price.
Let y represent the number of pieces of pottery that was sold at the new price.
They sold some of their pottery at the original price of $9.50 for each piece. This means that the amount that they got from selling x pieces of pottery at the original price would be 9.5x
They later decreased the price of each piece by $2. This means that the new price was 9.5 - 2 = $7.5
This means that the amount that they got from selling x pieces of pottery at the new price would be 7.5y
If they sold all 90 pieces and took in $729, then the equations are
x + y = 90
9.5x + 7.5y = 729 - - - - - - - - - -1
Substituting x = 90 - y into equation 1, it becomes
9.5(90 - y) + 7.5y = 729
855 - 9.5y + 7.5y = 729
- 9.5y + 7.5y = 729 - 855
- 2y = - 126
y = - 126/- 2 = 63
Substituting y = 63 into x = 90 - y, it becomes
x = 90 - 63 = 27
