First, let's find g(4). After we find it, we can substitute the value into f(x).


To find g(4), we need to substitute x = 4 into the function g(x), as shown below:

g(x) = x^2 - 7

g(4) = 4^2 - 7

g(4) = 9


Now that we have found g(4) = 9, we can substitute this value in for x in f(x).

f(x) = 3x + 1

f(9) = 3(9) + 1

f(9) = 28


f(g(4)) is equal to 28.

Answer:

5.25 miles

Step-by-step explanation:

We are required to determine the distance between Lighthouse A and Lighthouse B in the diagram.

Using Law of Cosines

c^2=a^2+b^2-2abCosC\\c^2=7^2+4^2-2(7)(4)Cos48^\circ\\c^2=27.5287\\c=\sqrt{27.5287} \\c=5.25\: miles

The distance between lighthouses is 5.25 miles.

4. Here is a linear equation: y=1/4 x + 5/4
4vir4ik [10]

Step-by-step explanation:

"Solutions to the equation" just means that they are points on the line. To find out if these two points land on this line, plug each one in, like this:

1.5 = (1/4)(1) + (5/4)

1.5 = (1/4) + (5/4)

1.5 = (6/4)

1.5 = 1.5

Since the expression is true, this point is on the line.

Do the same process for the second point (remember a point is formatted (x,y)) and see if it is also a point on the line.

To find the x-intercept, simply plug in 0 for y and see what you get. It should look like (x,0).

2p - q + 4 - p + q

By rearranging the terms

2p - p + 4

( you might think where -q and +q went ???

They are cancelled because they have opposite signs )

∴The answer is p + 4
