<span>Find
the number of bluejays bird and robins birds as joan counted it
=> the number of Robins is twice as bluejay
=> Robins = 2X
=> The number of bluejay is about to know:
=> Bluejay = X
The total number of birds is 21.
=> 2X + X = 21
=> 3x = 21
=> 3x / 3 = 21 / 3
=> x = 7
Thus the number of bluejay is 7
=> Robin = 2(7)
=> Robin = 14
Thus the number of Robin is 14</span>
Since 150 is the total and 12 is per week you can actuality do this equation
T= Total,150$ W=Amount saved,12$
150=12*X or 150/12=X
While X = 12.5 Weeks So, the correct answer
is 12.5 Weeks it can be stated As,
12 weeks 3 days 12 hours (X=12.5)
28% of 942 = 263.76
942 - 263.76
= $678.24
Answer:
f(x)=5(2^x)
Step-by-step explanation:
We have been given the parent function
We have the transformation rule:
Rule: If the parent function y =f(x) is stretched vertically by a factor 'k' then the equation becomes y=kf(x).
Here, the exponential function vertically stretched by a factor 5, hence, k = 5.
