Answer:
Multiply input by 4.
Step-by-step explanation:
So, all we have to do is find the difference between the input/output.
So for the first one.
4y=1x
Divde both sides:
1y=1/4x
Next we have 16y=4x
Divide both sides:
1y=1/4x
Ok, so we now know that y is 1/4x
Or in otherwords, 4x is 1y.
Remember x is input, and y is output.
So we can think of this as the input times 4 equals the output.
This seems to be the second answer.
Hope this helps!
(2*x+3*y)*(x-y) this is expanded form
In a symmetric distribution, better known as the Gaussian or normal distribution, two thirds of the observations or 66.67% of the observation belongs to the area between the -3∅ to +3∅ where ∅ is the standard deviation of the group. it is assumed here that the mean is 1 and the area under the curve is also 1.
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
y is the average annual salary
x is the number of years
r is the rate of change
a is the initial value
In this problem we have

substitute


For x=4 years

1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5
2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.
3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.
