Y α x²
y = kx²
64 = k*4²
64 = k*4*4
64 = 16k
64/16 = k
4 = k
k = 4
y = kx²
y = 4*6²
y = 4*6*6
y = 144

Step-by-step explanation:
Answer: x=-3
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
To find the slope through 2 points
m = ( y2-y1)/(x2-x1)
= ( -4 - -3)/(3 - 3)
= ( -4+3)/(3-3)
= -1/0
Since it is a number divided by zero, the slope is undefined
Answer:
<em>9.3 + b = 14.5</em>
Step-by-step explanation:
We are learning about perimeter.
Look for the formula of the perimeter,
P = a + b + c
The question states "The longest side is twice that of the shortest side."
A is the longest side while b is the shortest side.
The shortest side equation would be found below :
6.2 = 2c
c = 3.1
Making a completion of the longest side :
14.5 = 6.2 + 3.1 + b
14.5 + 9.3 + b
