Answer:
see explanation
Step-by-step explanation:
Use the points to find a and b, that is
(2, 18)
18 = a → (1)
(4, 162)
162 = a → (2)
divide (2) by (1)
= = 9
b² = 9 ⇒ b = 3
substitute b = 3 into (1)
18 = 9a ⇒ a = 2
y = 2 ← exponential equation
So we are given that the perimeter is 106 and two problems to solve
we will write this as an equation
106 = 3x + 6
we will subtract 6 from both sides
100 = 3x
now divide by 3 to isolate the variable
we will get 33 1/3 as the x
for the second one
106 = 2x - 3
add three to both sides
109 = 2x
divide by 2 to isolate the variable
we will get 54 1/2 as the x
Hope this helps :)
Answer:
-14
Step-by-step explanation:
Think of it like this-
subtracting a negative is like adding a positive, so all you have to do is add a negative sign to the sum after solving these sort of problems :>
Hope this helps!
