Answer: y = 48/x
Step-by-step explanation:
y ∝ 1/x
Introducing the proportionality constant, we have
y = k/x
substituting the value of x and y , we have
6 = k/8
k = 48
Therefore the equation becomes
y = 48/x
Answer: c) 14,871
Step-by-step explanation:
See photo attached - if my work doesn’t make sense I can explain it, just ask (:
Always, ALWAYS remeber this format: y = mx + b
In this equation, 'm' is the slope, and 'b' is the y-intercept
When you're trying to find a slope, remember that the equation is 
When finding the rise and run, look at two points that are on the graph AND on the line as well. Essentially, make sure the points you're using are integers.
In this, case, the rise is -3, and the run is 2. This means that the slope is 
Now we have the first part of our equation:
y = -
+ b
But wait! How do we find b?
Sometimes you have to input x in order to find it, but only when you're not supplied with a graph. In this case, all you have to do is look!
The point of the line that is on the y-axis is called the y-intercept.
In this graph, the y-intercept is -1
Now we have our complete equation!
y = -
- 1
Good luck!
Step-by-step explanation:
d=days not used
50-2d = 40-1.5d
subract 40 each side
10-2d =1.5d
10= 0.5d
20=d
After 20 days the value of the gift cards will be equal.
20*2=40 50-40=10 ($10)
20*1.5=30 40-30=10 ($10)
each card will have a value of $10 after 20 days,when both cards have equal value
Make a word problem... I think.
Janie needs to knit 5 shirts. Maddy needs to make 12.5 shirts.They need to do this every day for 9.5 days. How many shirts in total (Maddy and Janie combined) do they make by the end of the 9.5 days?
Answer:
9.5 x (8 + 12.5)
9.5 x 20.5194.75 shirts in total
Did that help?
