Y-x =17
y = -x + 17
substitute this into the second equation
y = 4x + 2
-x + 17 = 4x + 2
0= 5x -15
15/5 = 5x/5
3 = x
Answer:26 last one 25 first and 3 middle
Step-by-step explanation:
Answer:
C, f(x) = 3(2)^x
Step-by-step explanation:
Since the y-intercept is 3, the function will have 3 multiplying by some number to the power of x.
As x increases by 1, we notice that y multiplies by 2 every time.
This leads us to believe that the equation is 3 * 2^x
So, 80 - 8. equals 72 / 2 = 36... then add 36 + 8 to one and you have 44...
44 for length and 36 for width
