When we are given a function f(x) and we are asked for f(a) [a is any number], it means to replace (or substitute) a into x in the function (x=a)
In this problem, we are asked to replace x with 2 in f(x), the first equation, and replace x with 3 in the second equation.
It looks like this:
f(2) = 2^3 + 5(2)^2 = 8 + 5(4) = 8 + 20 = 28
g(3) = 2(3) + 4 = 6 + 4 = 10
We finally just add these two numbers from f(2) and g(3) and get 28 + 10 = 38
Answer:
the answer is the A
Step-by-step explanation:
A coordinate system in geometry is a system that employs one or more integers. The coordinates of point H are (66, -19).
<h3>What are coordinates?</h3>
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The coordinates of point A are (-3, 9), and the coordinates of point B are (9, 5). Therefore, the difference between any two coordinates can be written as,
Difference
x ⇒ 9 - (-3) = 9 + 3 = 12
y ⇒ 5 - 9 = -4
Now, since the point are at equal distances, therefore, the difference in their coordinates will be the same as well,
The coordinates of point C are,
x = 9 + 12 = 21
y = 5 + (-4) = 1
- The coordinates of point C are (21, 1).
- The coordinates of point E are (39, -7).
- The coordinates of point H are (66, -19).
