Answer:
a. x - intercept = (-9, 0)
No, y-intercept
Step-by-step explanation:
Since equation of line is x = - 9,
If we draw a graph of it, we will find that line will go parallel to y-axis intersecting x-axis at (- 9, 0).
Hence,
x - intercept = (-9, 0)
No, y-intercept
is the correct answer.
Answer:
Domain: x ≥ 7
Range: y ≥ -1
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted from function f(x).
We know that we can't take a square root of a negative and get a real number. The closest we can get is the square root of zero, no less.
What x-value renders the square root 0? x = 7 does, and we can't go less than that or we will get imaginary numbers. Therefore, the domain is x ≥ 7.
To find the range, we simply solve the rest of the function when x = 7, as we cannot go any lower.
y = 0 - 1
y = -1
Therefore, our range has to be y ≥ -1 because that would be the lowest y-value outputted from the lowest x-value.
The "outer" terms are x and -6, so their product is -6x.
The "inner" terms are +5 and x, so their product is 5x.
The sum of "outer" and "inner" terms is -6x +5x = -x. (selection B)
Quadrant IV is the answer
Answer:
a=6
b=5.5
Step-by-step explanation:
not very sure but..
since 8X2=16,
a=3X2
b=11/2
