Answer:
a
Step-by-step explanation:
solve for y in one equation
2x + y = -4
y = -4 - 2x
plug y into the other equation
5x + 3y = -6
5x + 3(-4 - 2x) = -6
5x -12 -6x = -6
-x - 12 = -6
-x = 6
x = -6
plug x into the equation to find y
y = -4 - 2x
y = -4 - 2(-6)
y = 8
ordered pair: (-6,8)
The third statement does not describe a correlation all relationship because some children’s vocabulary does not increase as they get older, but their weight does.
Answer:
B. The domain of the graph is all real numbers less than or equal to 0
Step-by-step explanation:
First, let's find the domain.
(negative infinity, 0} or All real numbers less than or equal to 0
Second, range.
[0, positive infinity) or All real numbers greater than or equal to 0
Right off the bat we can eliminate A, C, and D. We are left with choice B. as the answer.
15 minutes = 1/4 of an hour = 0.25
64 x 4.25 =272 miles total
