As the function is
y = 10,000 + 350x , Here x is the number of months elapsed and y is the amount after x number of months.
This function is for the form
y = mx +b or y = b +mx
which is the form of a linear equation
So the given function is a linear function.
So a is true
a)The function is a linear function.
Also The function is increasing at a constant rate , So options C and E are also correct
So
A, C and E

Answer:
- rewrite: 2x^2 +5x +20x +50
- factored: (x +10)(2x +5)
Step-by-step explanation:
I find this approach the most straightforward of the various ways that trinomial factoring is explained or diagramed.
You want two factors of "ac" that have a total of "b". Here, that means you want factors of 2·50 = 100 that have a total of 25. It is helpful to know your times tables.
100 = 1·100 = 2·50 = 4·25 = 5·20 = 10·10
The sums of these factor pairs are 101, 52, 29, 25, and 20. We want the pair with a sum of 25, so that's 5 and 20.
The trinomial can be rewritten using these factors as ...
2x^2 +5x +20x +50
Then it can be factored by grouping consecutive pairs:
(2x^2 +5x) +(20x +50) = x(2x +5) +10(2x +5) = (x +10)(2x +5)

<em>Additional comment</em>
It doesn't matter which of the factors of the pair you write first. If our rewrite were ...
2x^2 +20x +5x +50
Then the grouping and factoring would be (2x^2 +20x) +(5x +50)
= 2x(x +10) +5(x +10) = (2x +5)(x +10) . . . . . same factoring
Answer:
Step-by-step explanation:
Io
The angles are supplementary angles. When the sum of the angles are 180 degrees they are called supplementary. Thus, the two angles given in the problem is supplementary since when you add it up it will sum up to 180 degrees.
