Answer:
a = 1, b = 3.
Step-by-step explanation:
a + b = 4
a - b = -2 Adding to eliminate b:
2a = 2
a = 1
So 1 + b = 4
giving b = 3.
9=5 -y/3
-5
3=-y/3
cross multiply
1=-y
y=-1
The <em>correct answer</em> is:
C) The quantity of distance measured in feet depends on the quantity of time measured in minutes.
Explanation:
The rate of an airplane's descent would be found using the distance it descends and the amount of time that takes.
In this situation, the amount of time that passes causes the distance the plane descends to change; this means that the distance depends on the time.
Answer:
C. -0.7
Explanation:
Given the equation:
First, distribute the bracket on the left-hand side:
The number that makes the given expressions equivalent is -0.7.
The correct choice is C.
Answer:
(-3,5)
Step-by-step explanation:
If the slope of y=x is 1, then you have to reflect over that line with a negative slope. It should reflect over to be (-3,5).
