Answer:
(x-5) (x+4)
Step-by-step explanation:
x^2 -x -20
What two terms multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
(x-5) (x+4)
A decimal problem may be a addition problem you would need to regroup the hundredths to solve, like a money problem
Answer:
The parent function of f(x) = (x-2) (x-1) is
.
Step-by-step explanation:
Here, f(x) = (x-2) (x-1)
Now, parent function of a given function is the function, which is PRODUCT OF ALL IT S FACTORS.
Now, here, f(x) has two factors ( x- 2) and ( x-1)
So, the parent function p(x) of f(x) is given as the product of both the factors.
So, we get:

Hence, here the parent function of f(x) = (x-2) (x-1) is
.
Answer:
0.006369
Step-by-step explanation:
Given that a test consists of 10 multiple choice questions, each with five possible answers, one of which is correct.
By mere guessing p = probability for a right answer = 1/5 =0.20
There are two outcomes and each question is independent of the other.
X no of questions right is Bin (10,0.20)
the probability that the student will pass the test
= prob of getting more than 60%
=
=0.006369
Answer:
<h2>x = 3/2</h2>
Step-by-step explanation:

Expand



Collect like terms and simplify

Divide both sides of the equation by 4
