Answer: one second
Step-by-step explanation:

Directly proportional, both increase/decrease, Multiple k(constant you needed to solve for)..
Inversely --one increases as the other decreases, increase the denominator & fraction gets smaller.... So
Problem:
Dirextly to X (× by X)
Inversely to Y, (÷ by Y)
Z= k X/Y
Solve, working backwards: Z =5 becomes
5 = k (X) ÷ (Y). And
X=15 and Y =9 becomes
5= k(15)/(9). Undo ÷9, ×9 both sides
45= k(15). Now undo ×15 by ÷15 both sides
45/15 = 3. So k=3, (also called your constant of variation)....and your Equation/Proportion becomes...
Z = 3X/Y
Use the new #s.... X=23, Y=14
Z= 3×23÷14 = 69/14. If they want spirochete answer divide and round to corresponding # if decimals
Answer:
y=2/15x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-5-(-3))/(-15-0)
m=(-5+3)/-15
m=-2/-15
m=2/15
y-y1=m(x-x1)
y-(-3)=2/15(x-0)
y+3=2/15(x)
y+3=2/15x
y=2/15x-3
Answer:
1000 rounded to the nearest ten is:
1000
Step-by-step explanation:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Answer:
(.5 , 0) (7.8 , 2.4)
Step-by-step explanation:
The solution to a system of equations is when they cross each other on a graph.
When this is graphed you case use the trace and zoom in tools to find where they are solutions at.
