Hello!
You put -2 in for x
I don't know whether it is times x or to the power of x so I will do both
5 * 3 * x
5 * 3 * -2 = -30
------------------------------------------------------------------------------------------------------
5 * 3^x
5 * 3^-2
5 * 1/81 = 5/9 or 0.55555
Hope this helps!
Answer:
After 16 months, Kenya will have paid $5,550
Step-by-step explanation:
This is a guess and check type of a problem. You guess a number of months, plug it into x, and see if both equations come out with the same answer.
If you plug 16 into the first dealer's equation, you get y= 200(16) + 2350. Solving this equation will mean y equals 5550.
If you plug 16 into the second dealer's equation, you get y= 175(16) + 2750.
Solving this equation will mean y also equals 5550.
Answer:
y = 
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 = 
12^2 - 11^2
= 144 - 121
= 23
square root (23) = 4.79 = 4.8
