Answer:
x=4+√23 , 4-√23
Step-by-step explanation:
x^2-4x=4x+7
x^2-8x-7=0
now solving from quadratic equation
x=4+√23 , 4-√23

It is 5 because any thing times 1 is that number
Answer:
Well, if <em>y </em>is 1
Then the equation would be y = 1 (2x)
So, depending on the answer options. Y would be double of whatever the X value is.
See how 1 X value is worth 2 Y?

Answer:
Step-by-step explanation:
y = k*x This is the formula for a direct variation.
- y = 20
- x = 4 Substitute these values into the direct variation
20 = 4 * k Divide by 4
20/4 = 4k/4
k = 5
Answer: the constant of variation is 5
