The descriminant is b^2-4ac so for 26 it would be -5^2 - 4 (1) (7). The quadratic formula is -B plus or minus the square root of b squared minus 4ac over 2a
If a shape is a square, this mean that each side has the same length. This means that each side of the square has a length of 17cm. Perimeter is the length of the outer boundary of a shape or the summation (addition) of all the sides. This means that the perimeter of this square is 17+17+17+17 or 17×4 which is equal to 68cm.
I hope this helps!
Y=1
x=7
that's the answer !!
35x=245
so you would divide both sides by 35
x=7
so it would take her 7 weeks or 1 month and 3 weeks to pay her friend back

Answer: vertical line.
Step-by-step explanation:
Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")
We have one rule for functions, each input can be mapped into only one output.
So if for example, for a given value x = A.
f(A) = B
and
f(A) = C
This is mapping the input A into two different outputs, then this is not a function.
Now to the question.
If we have a vertical line (parallel to the y-axis)
This line will have only one value of x associated with it, but all the values of y.
This means that this maps one value of the input into infinite outputs, then this can not be a function.
