Just put in the x values for example
First one x = 1
y = 2(1) + 5
y= 7
I’ll tell u all the answers here in order:
7

Answer:
Domain: (-∞, -5) ∪ (-1, ∞)
Step-by-step explanation:
Note:
For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.
For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.
We need to find the domain of f(x) for which f(x) < 0
From the graph, we can tell:
f(x) < 0 on (-∞, -5) ∪ (-1, ∞)
Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)
Answer:
no.
Step-by-step explanation:
The survey has too small of a group to be random.
First, you find 5% of $50.
To do this, you times 50 by 0.05. This is because if you were to turn 5% into a decimal, with 1.0 being 100%, 5% would become 0.05.
50 x 0.05 = 2.5
After you have the amount, simply add it onto the original $50.
50 + 2.5 = 52.5
The new price is $52.5.
