You have to solve 3x = 0, which is at x=0. The y intercept is the point (0,0), also known as the origin.

Answer:

(0,0)

Step-by-step explanation:

To find the y-intercept of a graph, you need to make x = 0 and then solve the equation for y.

In this case we have g(x) = 3x. This can also be written as y = 3x

So we're going to make x = 0 and solve for y:

y=3x\\y=3(0)\\y=0

Thus, the y-intercept of the graph is (0,0)

find two positive real numbers such that they sum to 108 and the product of the first times the square of the second is a maximu
topjm [15]

The two positive numbers are 36 and 72 which gives a sum equal to 108 and the product of 36 and the square of 72 is a maximum.

Any integer greater than zero is considered a positive number. A positive number can either be written as a number or with the "+" symbol in front of it.

Let us consider the two positive real numbers as x and y. Then, their sum is written as,

x+y=108

Then, y=108-x

And the product is written as,

P=xy²

Substitute value of y in the above equation, we get,

\begin{aligned}P&=x(108-x)^2\\&=x(11664-216x+x^2)\\&=11664x-216x^2+x^3\\&=x^3-216x^2+11664x\end{aligned}

Now, differentiate P with respect to x, and we get,

\begin{aligned}\frac{dP}{dx}&=3x^2-432x+11664\\&=x^2-144x+3888\end{aligned}

Solving the above equation to zero, we get,

\begin{aligned}x^2-144x+3888&=0\\x^2-36x-108x+3888&=0\\x(x-36)-108(x-36)&=0\\(x-108)(x-36)&=0\\x&=\text{108 or 36}\end{aligned}

Substitute values of x in y=108-x, to get values of y.

If we substitute x=108, we get the y value as zero which doesn't give the required solution.

But, if we substitute x=36, we get,

\begin{aligned}y&=108-36\\y&=72\end{aligned}

Thus, the two positive numbers are 36 and 72.

Answer:

  3 < b-a < 7

Step-by-step explanation:

The maximum difference will occur when the smallest 'a' value is subtracted from the largest 'b' value:

  9 -2 = 7

The minimum difference will occur when the largest 'a' value is subtracted from the smallest 'b' value:

  7 -4 = 3

So, the possible range of values of b-a is ...

  3 < b-a < 7

Evaluate the expression:<br><br> for y = 2 + 3x when x=4. What does y=?
lora16 [44]

Answer:

y = 14

Step-by-step explanation:

Plug in 4 as x into the equation:

y = 2 + 3x

y = 2 + 3(4)

Simplify:

y = 2 + 12

y = 14

So, when x = 4, y = 14.
