Here's the equation for direct variation. k=y/x [ f(x)=y]
Find k
k= 48/8=6
6=y/2
y=12
Hope this helps.
4 because 8 x 3= 23 but 8 x 4= 32 so thre will be some left over.
Answer:
$7,865,000 + (Claire's cases)
Step-by-step explanation:
Euro 2,500,000 x 1.13 = $2825000
£4,000,000 x 1.26 = $5040000
$5040000 + $2825000 = $7865000
Answer:
Part A: Kimberly
Part B:
Becca = 22.5 miles, Kimberly = 25 miles
Step-by-step explanation:
Part A:
Given that Becca runs at a constant speed of 4.5 miles per hour, use the table to find the constant speed that Kimberly runs, and compare who runs faster.
Let x = time
y = distance
k = speed = y/x
Equation for each person can be written as: y = kx
Therefore:
✔️Equation for Becca if k = 4.5
y = 4.5x
✔️Find k (speed) of Kimberly using (2, 10):
Speed (k) = y/x
k = 10/2
k = 5 miles per hour
Equation for Kimberly would be:
y = 5x
Comparing their speed, Kimberly runs faster because she covers more miles per hour than Becca does.
Part B:
For Becca, substitute x = 5 into Becca's equation, y = 4.5x
Thus:
y = 4.5*5 = 22.5 miles
For Kimberly, substitute x = 5 into Kimberly's equation, y = 5x
Thus:
y = 5*5 = 25 miles
A square since all sides are equal and the angles aren't acute so it can't be a rhombus
