P= 3

Q= -14

R= -5

Step-by-step explanation:

Just solve the equation on the right side, you'll get:

=3x^2 -15x +x -5

=3x^2 -14x -5

Now compare it to the equation on the left side,

The coefficient of x^2 on the left is "p", on the right that we just solved is 3.

Same for "q" which is the coefficient on the left, on the right it's -14.

And for "r" it's -5 from the equation on the right.

Answer:

The area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.

Step-by-step explanation:

Given that the dog pen for Ruth's dog is 7 feet long and 6 / 1.3 feet wide, while her friend Ralph's dog pen is 14 feet long and 6 / 1.2 feet wide, to determine how many times larger is the area of Ralph's dog pen, the following calculation must be performed:

1/3 = 0.333

1/2 = 0.5

7 x 6.333 = X

44,333 = X

14 x 6.5 = X

91 = X

44,333 = 100

91 = X

91 x 100 / 44.333 = X

9,100 / 44,333 = X

205.26 = X

100 = 1

205.26 = X

205.26 / 100 = X

2.05 = X

Thus, the area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.

r = - 18

multiply both sides by 3 to eliminate the fraction

3 × 6 = - r ⇒ 18 = - r ⇒ r = - 18

Determine if each statement about the relation {(3,7),(5,1),(6,4),(2,5)} is true or false.

s2008m [1.1K]

Answer:

a. true

b. true

c. True

Step-by-step explanation:

a. The domain of a relation includes all possible set of data that are the x-values. Therefore, the domain of the relationship given would be: {2, 3, 5, 6}.

a is True.

b. The range includes all corresponding y-values. Therefore,

Range would be {1 4, 5, 7}

b is Tire.

c. There's 5 on both range and domain.

c is hungry.
