Answer: Rectangle
If you let
P = (0,0)
Q = (0,b)
R = (a,b)
S = (a,0)
you'll be able to find that
PQ is a vertical line with undefined slope
QR is a horizontal line with slope 0
so PQ and QR form a right angle as they are perpendicular lines
You'll find this with the other line pairings as well. We'll have four right angles
Answer:
Step-by-step explanation:
i) 
The equation can still be solved but it should be stated clearly at what value of would the equation be undefined. For instance, you have an expression,
1/x+2
When x is equal to -2, the denominator will be 0 resulting to an undefined solution. The value of x here can be any real number except -2.
to graph f (x) + k, move the graph k units up..your answer should be;
y = x ^ 2 + 5/2
Answer:
degree 4
Step-by-step explanation:
The degree of a polynomial is determined by the term with the largest exponent for the polynomial in standard form
Given
P(x) = (x - 1)(x + 2)(x + 3)(2x - 5)
We need only consider the product of the leading terms in each factor, that is
x(x)(x)(2x) = 2
← is the leading term in the expansion of the factors
with exponent 4
Thus polynomial is of degree 4
