Answer:
Seth watched TV for 6 3/4 hours last week.
Step-by-step explanation:
Let x be the number of hours he watched TV last week.
(2/3)x = 4 1/2 hrs. Solve for x by mult. both sides by (3/2):
(3/2)(2/3)x = (3/2)(9/2)
Then: x = 27/4 hours, or 6 3/4 hours.
Seth watched TV for 6 3/4 hours last week.
1.

4 + 7 or 4 - 7 = 11 or -3
2.
pi is a real number. It is not imaginary or complex, so it definitely belongs to the set of real numbers.
pi is not a whole number or a rational number. It cannot be written as a fraction of integers. pi is irrational.
Therefore, pi is real and irrational.
Pythagorean theorem states that:
c^2=a^2+b^2
where:
c=hypotenuse
a and b are the legs
this implies that, a and b are shorter than c; thus to find the Pythagorean theorem we look for values that satisfy the above equation, where c is the longest side.
17^2=15^2+9^2
thus (17,15,9) are Pythagorean triple.
13^2=5^2+12^2
Thus (5,12,13) are Pythagorean triple
12^2≠6^2+8^2
Thus they are not Pythagorean triple
6^2=5^2+3^2
Thus (3,5,6) are not Pythagorean theorem.
Answer:
No, the graph fails the vertical line test
Step-by-step explanation:
To determine if the graph is a function, we can use the vertical line test.
Use a vertical line, if the vertical passes through two or more points, the graph is not a function
Looking at the y axis ( which is a vertical line), it passes through two points
This means the graph is not a function
No, the graph fails the vertical line test
The slope can be found by the "rise over run", that is, is the change in variable y divided by the change in variable x.
