Answer & Step-by-step explanation:
For this problem, all we have to do is add f(x) to g(x). So, we will add (x -2) to (x² + x - 6).
(x - 2) + (x² + x - 6)
Combine like terms.
x² + (x + x) + (-2 + (-6))
x² + 2x - 8
So, (f + g)(x) is equal to x² + 2x - 8
Answer:
y = 4/7x - 4
Step-by-step explanation:
You first have to put it in y = mx + b form
So, we first subtract 4x from both sides: -7y = -4x + 28
Divide both sides by -7
y = 4/7x - 4
Now to graph you have to start at the starting point which is -4
So we start with our point on -4 then move up 4 times and 7 times to the left. Mark the points then draw your line!
The given sequence is x-1, -2x+2, 4x-4, -8x+8 .
Notice that this is a geometric sequence because here we have equal common ratio.
So, common ratio : r =
=
= Take out -2 as common factor
= -2 Cancel out x - 1.
The formula for general term of a geometric sequence is,
Where, first term:
We need to find the 10th term of this sequence. So, n = 10.
Next step is to plug in these values in the above formula to get the 10th term. Hence,
So, A is the correct choice.
<u>To find the constant of proportionality:</u>
⇒ must define constant of proportionality
⇒ <em>Constant of Proportionality: ratio of two proportional values at a </em>
constant value
⇒ (in this case) two proportional values are x and y
<u>The ratio between x and y is equal to</u>
