Answer:
2 miles is your answer hope this helps!!!!!!
Step-by-step explanation:
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x+7 f - 1 ( x ) = x + 7 is the inverse of f(x)=x−7 f ( x ) = x - 7 .
hope this helps.
Answer:
Pictures clicked by Drew = 27
Pictures clicked by Danielle = 97
Step-by-step explanation:
The pictures captured by both of them = 124
Let us assume the pictures clicked by Drew = m
So, Pictures captured by Danielle = 16 + 3( Pictures clicked by Drew)
= 16 + 3 m
Now, Total Pictures clicked by (Drew + Danielle) = m + (16 +3 m )
⇒ m + (16 +3 m ) = 124
or, 4 m = 124 - 16
⇒ 4 m = 108
or, m = 108/4 = 27, or m = 27
Hence, the pictures clicked by Drew = m = 27
and the pictures clicked by Danielle = 16 + 4m = 16 + 81 = 97
Answer:
D is false
Step-by-step explanation:
f(x) = -2x2 + 4x + 6 should be written with a " ^ " to indicate exponentiation:
f(x) = -2x^2 + 4x + 6.
Because of the - sign, we know that the graph of this function opens down, so there is a maximum at the vertex. We can determine the x-value at the vertex by using the formula x = -b/(2a), which here is x = -4/(2*-2), or 1.
Evaluating f(x) = -2x^2 + 4x + 6 at x = 1, we get -2 + 4 + 6, or 8. So statement A is true: there's a max at (1, 8). This is also the vertex of the graph.
Let's now look at C and D. We evaluate f(x) at x = 3 and x - 2. If the output (y) value is 0, we know we have an x - intercept:
f(3) = -2(9) + 4(3) + 6 = 0. Yes, C is true, (3, 0) is an x-intercept.
f(-2) = -2(4) - 8 + 6 is not 0. Therefore D is false; (-2, 0) is not an x-intercept.
Look at B: Let x = 0 and find y: it's 6. Thus, (0, 6) is the y-intercept. B is true.
