More = Addition
"Twice a Number" = Multiplication (specifically by two)
Since the order of operations tell us to multiply before we add, we can simplify
.
Answer:
See below.
Step-by-step explanation:
Part A: A system will have no solution when the graphs are parallel and do not intersect.
Part B: A system will have no solution when the equations have the exact same slope. The same slope means they are parallel and do not intersect. This is done easiest in slope-intercept form.
Answer:
(a) f(0) = 1
(b) f(3) = 5 (I'm not sure about this one, it's either this or undefined)
(c) f(-2) = 3
(d)
(e)
(f)
(g) DNE, because the limit of x--> 1 from the left is 2, and the limit from the right is 1. Because they don't approach the same value from both sides, the limit doesn't exist.
Answer:
x-intercept: (-5, 0)
y-intercept: (0, -4)
Step-by-step explanation:
The x-intercept is as the name implies when the line intersects the x-axis (the horizontal axis) or when y is equal to 0. If you look at the graph it intersects the x-axis at (-5, 0). The y-intercept follows the same concept except it's when it intersects the y-intercept (vertical axis) or when x is equal to 0. If you look at the graph it, it intersects the y-axis at (-4, 0).
