If you trace the path while counting, you'll find the answer is a little over 3 seconds and not quite 4 seconds. Thus leaving 3.9s
Step-by-step explanation:
step 1. break into 2 shapes: a rectangle of sides 3 and 4. a triangle of sides (x - 3), 4, and y.
step 2. y = 4sqrt(2) (definition of a 45° triangle)
step 3. note: sqrt is the square root.
step 4. x - 3 = 4 (definition of a 45° triangle)
step 5. x = 7 (add 3 to both sides).
First, divide 30 by 2, then times that by 20. Or, you could times 30 by 10<span />
A proportional relationship is between two variables where their ratios are equivalent. Another way to explain is one variable is always a constant value times the other . Which is known as the “constant proportionality”
Answer:
y = -3x
Explanation:
k = -3
y ¤ x......where ¤ represents the Greek alpha sign
y = k • x
y = -3 • x
y = -3x
