Answer:
Find the "zeros" and plug in points
Step-by-step explanation:
You can tell this graph is a parabola.
We can find the "zeros" of the graph to help us.
Find the zeros:
2x-1=0
2x=1
x=0.5
2x-5=0
2x=5
x=2.5
We can substitute values into f(x)=(2x-1)(2x-5) to graph.
You should get (1.5,-4) to be the vertex.
Hope this helps
Answer:
90 nickels and 15 dimes
Step-by-step explanation:
If one is six times the other, then you would have 7 equal piles. Divide 105 by 7 to get 15 which is the number in each pile(number of dimes). Then 105 minus 15 gives you the total of the rest of the piles(number of nickels).
Check:
90 plus 15 equals 105, and
15 times 6 equals 90.
So if the perimeters are equal then you know
Rectangle Triangle
x + x + x + 4 + x + 4 = x + x + 9 + x + 5
which becomes
4x + 8 = 3x + 14
now you can solve the equation for x, then find the perimeters
Answer:
The 8th term in the sequence is -128
Step-by-step explanation:
The given series is a geometric progression (G.P) with the starting term as -1.
Let the starting term be a and the common ratio be r.
a = -1
r = 2
The formula for the nth term of a geometric progression (G.P) :

n = 8

Therefore, the 8th term in the sequence is -128
