Answer:
35
Step-by-step explanation:
3x-15=90
3x=90+15
x=105/3
x=35
Given exponential function:

Let us obtain three points including the y-intercept so that we can plot the function y = f(x)
When x =0:

when x =1:

when x =2:

We have the points : (0, 1), (1, 1/5), and (2, 1/25)
Using these points, let us provide a sketch of the plot of y =f(x). We have the plot as shown below:
Step-by-step explanation:
-4^(-5)/ 2^(-3) =
2³/(-4)^5 =
8/(-1024) =
- 1/128 (d)
800 - 50 = 750
750 ÷ 5 =150
150 small vehicles were washed
Answer:
x = 90°
Step-by-step explanation:
The diagonals of the kite AC and BD are perpendicular to each other
Hence x = 90°
