Answer:
x = 14; x = 0
Step-by-step explanation:
(x)(6 + 8) = x²
(x)(14) = x²
14x = x²
14x - x² = 0
(x)(14 - x) = 0
x = 14; x = 0
Answer:
10 units squared
Step-by-step explanation:
Looking at the figure, we can observe that it consists of two triangles: one on the left of the y-axis and one on the right. This means that we can find the separate areas of each triangle and then sum them to get the total area.
The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.
<u>Left Triangle</u>:
The base is 4 and the height is 4, so the area is:
A = (1/2) * b * h
A = (1/2) * 4 * 4 = (1/2) * 16 = 8 units squared
<u>Right Triangle</u>:
The base is 2 and the height is 2, so the area is:
A = (1/2) * b * h
A = (1/2) * 2 * 2 = (1/2) * 4 = 2 units squared
The total area is 8 + 2 = 10 units squared.

F -1(x) = 4x
If you supply 3 for the function of F so f(3) = 4x then 4 x 3 = 12
The inverse would be
One way to work out an inverse function is to reverse the operations that f carries out on a
number. Here is a simple example. We shall set f(x) = 4x, so that f takes a number x and
multiplies it by 4:
f(x) = 4x (multiply by 4).
We want to define a function that will take 4 times x, and send it back to x. This is the same
as saying that f
−1
(x) divides x by 4. So
f
−1
(x) = 1
4
x (divide by 4).
There is an important point about notation here. You should notice that f
−1
(x) does not mean
1/f(x). For this example, 1/f(x) would be 1/4x with the x in the denominator, and that is not
the same as 1
4
x.
Answer:15/20 3/4
Step-by-step explanation:
Because 3 times 5 =15 and 4 times 5= 20 so that will be 15/20
Then if you multiply 3 and 4 by 1 it will give you 3/4
