Patrick got a change of $14.90 for paying for the material with a $20 bill.
Explanation:
- 1 yard of material costs $3.40. Patrick bought 54 inches of material. First, we must convert the inches into yards. We have 36 inches = 1 yard. To calculate how many yards 54 inches we divide the 54 by the 36. So 54 inches of material = 54 / 36 yards = 1.5 yards of material
- Since 1 yard of material costs $3.40, the cost of 1.5 yards of material = 1.5 × $3.40 = $5.10. Patrick paid for the material with a $20 bill. So the change Patrick got = $20 - $5.10 = $14.90.
<span>y+2>1/2-2 looks a little strange. Is it OK to combine the last 2 terms?
</span><span>y+2> -3/2
Then y > -2 - 3/2, or y > -7/2. y must be greater than -7/2, greater than -3.5.</span>
Answer:
f(x) = -1/2x + 1
Step-by-step explanation:
Remember that f(x) = y
f(-2) = 2 tells you that when x = -2, y = 2 ; So you have point (-2, 2)
f(2) = 0 tells you that when x = 2, y = 0 ; So you have point (2, 0)
Now use the two points to find the slope: Slope = (change in y)/(change in x)
So slope = (0-2)/(2-(-2) = -2/4 = -1/2
Next find "b" using the slope and one point and solve for "b"
y = mx + b slope = -1/2 point (-2, 2)
2 = -1/2(-2) + b
2 = 1 + b
1 = b
Last thing to do: write the equation using slope = -1/2 and b = 1 into y = mx + b
y = -1/2x + 1
