Given y2 + 5y - 6 = (y + p)(y +q) find the
values of p and q.
Answer:
p = 6, q = - 1
Step-by-step explanation:
Factor the left side and compare to right side
y² + 5y - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)
The factors are + 6 and - 1, since
6 × - 1 = - 6 and 6 - 1 = + 5, thus
y² + 5y - 6 = (y + 6)(y - 1)
Compare with (y + p)(y + q) , then
p = 6 and q = - 1

If an object travels for 10 seconds at a velocity of 50 feet per second, how far did it travel?
Answer:
500
Step-by-step explanation:
50x10 = 500
50 feet per second so we multiply 50 (the speed per second) by 10 (the time given). You can also use a formula like this:
S x T
S= Speed
T= Time
How would I set up question one?
A straight line is 180 degrees:
25x + 8 + 9x + 2 = 180
Combine like terms:
34x + 10 = 180
Subtract 10 from both sides:
34x = 170
Divide both sides by 34:
X = 5
Now solve the smaller angle:
9x + 2 = 9(5) + 2 = 45 + 2 = 47
They angle with the y is a vertical angle to 47 so needs to also equal 47:
7y + 5 = 47
Subtract 5 from both sides:
7y = 42
Divide both sides by 7:
Y = 6
Answer: x = 5, y = 6

Which is a counterexample for the conditional statement shown?
If three distinct points lie in a plane, then the points can form a triangle.
The points form a different polygon.
The points form a circle.
The points form an open figure.
The points form a line.
Answer:
d
Step-by-step explanation:
If three distinct points lie in a plane, can also form a straight line. Therefore, option D is the correct answer.
Given that, if three distinct points lie in a plane, then the points can form a triangle.
We need to identify the counterexample for the conditional statement given.
What is a counterexample?A counterexample to a mathematical statement is an example that satisfies the statement's condition(s) but does not lead to the statement's conclusion. Identifying counterexamples is a way to show that a mathematical statement is false.
Now, if three distinct points lie in a plane, then the points always can not form a triangle.
If three distinct points lie in a plane, can also form a straight line.
Therefore, option D is the correct answer.

Personal behavior is the only factor that determines if a person becomes ill.
The answer is False. Personal behavior is not the only factor that determines an individual’s illness or sickness. There are other factors which determine an individual’s sickness and dysfunction. There are reasons like obesity which leads to several diseases.
This is false because genetics and environmental factors may also come into play. So there are many factors to be considered if a person becomes ill.

77 is written as the product of two prime numbers 7 × 11. Can 702 be written as the product of two prime numbers? If not, why? What about 703?
Answer:
702 can't be written as the product of 2 prime numbers because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore, 702 is a prime number.
The prime factorization of 703 is 19 × 37. Since it has a total of 2 prime factors, 703 is a composite number.

Write an integer for: a deposit of $45 * Plz help fast!
Answer:
$45
Step-by-step explanation:
A deposit is positive, so the integer will be positive.An integer is a whole number that's not a fraction, so a positive integer for 45, would be 45.I hope this helps!
An integer is a whole number that's not a fraction, thus a positive integer for 45, would be 45.
What are integers?Natural numbers are: 1, 2, 3, ....
Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )
Rational numbers are numbers which can be written in the form of a/b where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.
Irrational numbers are those real numbers which are not rational numbers.
Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.
