Answer:
x+46
Step-by-step explanation:
-32x+20+33x+26=
x+20+26=
x+46
For quadratic
.. ax^2 +bx +c = 0
the discriminant is
.. d = b^2 -4ac
You have
.. a = 2
.. b = -5
.. c = 7
so the value of the discriminant for your equation is
.. (-5)^2 -4(2)(7)
.. = 25 -56
.. = -31
Because the discriminant is negative, the roots of the quadratic are complex.
Reasoning: this is the usual interpretation of the sign of the discriminant. It derives from the fact that the square root of the discriminant is part of the roots of the quadratic. That part will be imaginary when the discriminant is negative.

The graph shows there are no real roots.
<u>ANSWER=5</u>
<u />
<u>EXPLANATION</u>
The Mode is known as the number that occurs most often in a set of data, so the data being 5,5,5,5,5 only has fives in it so the answer must be <u>5</u>.
304020 just say it in your head it will make sence
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
