If f={(-1,-3), (1,1),(2,3),(4,6)} and g={(-1,-1),(1,7),(4,3)} what is (f+g)(4)?

Answer:
(f + g)(4) = 9
Step-by-step explanation:
We have that:
f = {(-1,-3), (1,1),(2,3),(4,6)}
this means that:
f(-1) = -3
f(1) = 1
f(2) = 3
f(4) = 6
and we also know that:
g = {(-1,-1),(1,7),(4,3)}
hich means that:
g(-1) = -1
g(1) = 7
g(4) = 3
Now we want to find:
(f + g)(4)
For the general case of two functions f(x) and g(x)
(f + g)(x) = f(x) + g(x)
Then:
(f + g)(4) = f(4) + g(4)
and we know both of these values, so we can just replace them:
(f + g)(4) = f(4) + g(4) = 6 + 3 = 9
Then we get:
(f + g)(4) = 9
yes all proportional relationships are all linear relationships
non-proportional=non-linear
Answer:
4/27 chance of getting a white marble.
Step-by-step explanation:
There are 4 white marbles but there are 27 marbles in total. If you wanted a percentage, then divide 4 by 27 and place the decimal two places to the right once you founded your answer.

This is about understanding the meaning of a rectangle and parallelogram.
<u><em>Option A is the correct definition.</em></u>
<u><em /></u>
We are given the 2 statements as;
1) A rectangle is a parallelogram with 4 right angles
2) A rectangle is a parallelogram
- Let us define a rectangle and parallelogram;
- A rectangle is defined as a quadrilateral with four right angles. This means all the angles are equal. It also has 4 sides with the length of opposite sides being parallel to each other.
- A parallelogram is defined as a quadrilateral that has two pairs of parallel sides with the opposite sides of such parallelogram having equal length and the opposite angles being equal.
- Option A; This is correct because the reverse statement is that; A parallelogram is a rectangle with 4 right angles, This is possible because the only condition where a parallelogram is a rectangle is when it has 4 right angles.
- Option B; This is wrong because a rectangle is not a parallelogram.
- Option C; This is wrong because not all parallelograms are rectangles.
- Option D; This is wrong because a rectangle must have 4 right angles
