Answer:
Step-by-step explanation:
we have
Substitute the values of and in the expression to evaluate
x^2 - 9 = (x + 3)(x -3)
3x - 9 = 3(x - 3)
and
6
Common denominator would be 6(x+3)(x - 3)
Answer: 6(x+3)(x - 3)
Step-by-step explanation:
I'm guessing that "PQPA" means like Problem Question, Problem Answer (so what you are trying to find, and what it is (I think)).
That means the first problem is (3/4)+(7/8) = 13/8 and "How much water is collected in two hours?"
This means the second problem is (2 1/3) - (1 3/4) = (7/3)-(7/4) = 7/12 and "How many pounds of beef are left"
This means the third problem is (1 -(1/6))(2/5) = (5/6)(2/5) = 1/3 and "What fraction of her paycheck is saved"
This means that the fourth problem is (3/4)(2/3) = 1/2 and "How long did it take Megan to do her HW?"
Answer:
(x) =
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2 ( divide both sides by 2 )
= x
Change y back into terms of x and let x = (x), thus
(x ) =
B) if you are healthy, then you exercise.
C) if you don’t exercise, you won’t be healthier.
D) if you exercise, then you will be healthier.
2) which of the following is a conditional statement for the following statement? Cardinals are red birds.
A) if a bird is not red, then it is not a cardinal.
B) if a cardinal is red, then it is a bird.
C) if a bird is red, it is a cardinal.
D) if a bird is a cardinal, it is red
1. if you exercise, then you will be healthier.
2. if a bird is a cardinal, it is red
A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.
Given:
Exercise makes you healthier.
So, we have to write in the form of if- then statement
Thus, the statement is if you exercise, then you will be healthier..
Now, for the secondstatement "Cardinals are red birds."
The conditional statement is if a bird is a cardinal, it is red.

Answer:
D for both
Step-by-step explanation:
Exercise is the condition and healthier is the outcome. So if you exercise then you will be healthier.
