Answer:2 and 4 and the second one is 7 and 8
Step-by-step explanation:
Answer:
Let's talk through this a one step at a time.
*Since f(x) is concave-up with its vertex on the x-axis, we know f(x) ≥ 0.
*We also know that when we shift a function's domain by a positive number, we shift the function left and when we shift a function's domain by a negative number, we shift the function right. So f(x-5) is f(x) shifted to the right by 5.
*At this point, f(x-5) has its vertex at (5,0).
*When we negate f(x-5), the parabola becomes concave down yet the vertex remains at (5,0). Now we're at -f(x-5). At this point we have -f(x-5)≤0 with a range (-∞,0]
*If we add 2 to create g(x)=2-f(x-5), then we have a concave down parabola with its vertex shifted up by 2, at (5,2). So, g(x) is concave down with its vertex at (5,2). Hence
Answer:
x = 10 Perimeter: 129
Step-by-step explanation:
FINDING X:
4x+7 = 5x -3
7 = x -3
10 = x
x = 10
PERIMETER:
4x + 7 + 5x - 3 + 4x - 5
Combine the "x" values
13x + 7- 3 - 5
Combine the numbers
13x - 1
13(10) -1
130 - 1
129
Answer: 0
Explanation: Displacement is how far something or someone is from the starting point, in this case, the frog, so it moves 18F then 6B then 12B, so 0+18-6-12=0.
Hope this helps! :)
