Answer:
Ben is incorrect
The solutions are x>-3 and x < 3
Step-by-step explanation:
we have
Multiply by -1 both sides
Adds 9 both sides
The solutions are
and
-----> Multiply by -1 both sides ----> 
therefore
The solution is the interval (-3,3)

Answer:
#7: Vertex is (2,-6)
y-intercept is (0,6)
#8: Vertex is (-2,-29)
y-intercept is (0,-9)
#9: Vertex is (-1,1)
y-intercept is (0,-5)
#10: Vertex is (2,20)
y-intercept is (0,-8)

Graphs are in the picture below
Answer:
A: Not rational, because a rational number is any integer, fraction, terminating decimal, or repeating decimal. This does not show that.
B: In between 13 and 15, (200 rooted is 14.1) I know this because if you simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
C: He should make each side about 3.76 feet long. Because, 3.76^4 is 200, therefore it would become 200 square feet if each side is 3.76 feet long.

Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 13 → (1)
x + 2y = - 4 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = - 4 - 2y → (3)
Substitute x = - 4 - 2y into (1)
2(- 4 - 2y) - 3y = 13 ← distribute and simplify left side
- 8 - 4y - 3y = 13
- 8 - 7y = 13 ( add 8 to both sides )
- 7y = 21 ( divide both sides by - 7 )
y = - 3
Substitute y = - 3 into (3) for corresponding value of x
x = - 4 - 2(- 3) = - 4 + 6 = 2
Solution is (2, - 3 )
Answer: Elijah would be 42 inches tall
Step-by-step explanation:
We all know that Samuel is 48 inches while Elijah is 6 inches shorter.
You subtract 6 from 48 to get 42.
Hopefully, this helped. :D
