.49 its as simple as that :)
I would use the quadratic equation for this.
Answer:
The indifference point is 20 tiles.
Step-by-step explanation:
<u>First, we need to establish the total cost formulas for each store:</u>
<u></u>
Store 1:
Total cost= 10 + 0.99*x
Store 2:
Total cost= 1.49*x
x= number of tiles
<u>Now, we equal both formulas and isolate x:</u>
10 + 0.99x = 1.49x
10= 0.5x
10/0.5=x
20=x
The indifference point is 20 tiles.
Answer: y = 3x/2 + 8
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m represents the slope of the line.
The equation of the given line is
y = - 2x/3 + 5
Comparing with the slope intercept form, slope = - 2/3
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line passing through (2, 11) is 3/2
To determine the y intercept, we would substitute m = 3/2, x = 2 and y = 11 into y = mx + c. It becomes
11 = 3/2 × 2 + c
11 = 3 + c
c = 11 - 3 = 8
The equation becomes
y = 3x/2 + 8
