Answer:

The answer is -8 (Option B)

Step-by-step explanation:

You can solve this by replacing x in the equation with 8, because the question give us what x equals. So instead of y=8-2x, we get y=8-2(8)

Now that we have the complete equation, we can solve for y:

y= 8 - 2x

y= 8 - 2(8)

y= 8 - 16

y= -8

Answer: OPTION B.

Step-by-step explanation:

You know that the function is:

y= 8 - 2x

Then, in order to find the value of the variable "y" when the value of the variable "x" is 8 (x=8), you need to substitute this value into the function y= 8 - 2x.

Therefore, this is:

y= 8 - 2x\\\\y= 8 - 2(8)\\\\y= 8 - 16\\\\y=-8

Answer:

Population of town in Year 2010 is 3476.

Step-by-step explanation: Formula for the Population after t years is given by   P(t) = P (1-i/100)^n

        where P is initial population.

Here in question P is initial population.

If we compare the equation given in the question to the problem equation

13. t plus the product of three and t​
Sindrei [870]

Answer:

4t

Step-by-step explanation:

Let's form an equation here just to put it visually.

So it would be t+3*t

We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)

Now we can do t+3t which is 4t

If this doesn't make sense, then you can look at it this way

You do 1t+3t and since they're like terms, you can combine them and do 4t.

How to graph exponents and solve functions for graphs
hoa [83]
A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis
