Answer:
<u>The correct answer is D. y = -3x – 1</u>
Step-by-step explanation:
Let's find which of the following equations describes the relationship.
Answer A.
y = -x – 3
If x = 0 ⇒ y = -3; if x = 2 ⇒ y = - 5
Therefore, this is not the correct equation.
Answer B.
y = 3x - 1
If x = 0 ⇒ y = -1; if x = 2 ⇒ y = 5
Therefore, this is not the correct equation.
Answer C.
y = x – 3
If x = 0 ⇒ y = -3; if x = 2 ⇒ y = - 1
Therefore, this is not the correct equation.
Answer D.
y = -3x - 1
If x = 0 ⇒ y = -1; if x = 2 ⇒ y = - 7; if x = 5 ⇒ y = -16
Therefore, this is the correct equation.
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old
