Yes. It's a linear function.
<u>x | y</u>
<u>0| 2(0) = 0</u>
<u>1| 2(1) = 2</u>
<u>2| 2(2) = 4</u>
Answer:
-16
Step-by-step explanation:
x^2 -1 /x+4
By putting the value of x in the expression as x = -7
= (-7)^2 - 1/ -7 +4
= (+49) - 1/ -3
= 48/-3
= -16
Answer:
q = 8
Step-by-step explanation:
Given the 2 equations
p + q = 36 → (1)
p - q = 20 → (2)
Add the 2 equations term by term
2p = 56 ( divide both sides by 2 )
p = 28
Substitute p = 28 into (1)
28 + q = 36 ( subtract 28 from both sides )
q = 8
