Answer:
f(3)=21
Step-by-step explanation:
f(1)=3
f(n)=2f(n-1)+3
n=2
f(2)=2f(2-1)+3
f(2)=2f(1)+3
f(2)=2*3+3
f(2)=6+3
f(2)=9
n=3
f(3)=2f(3-1)+3
f(3)=2f(2)+3
f(3)=2*9+3
f(3)=18+3
f(3)=21
Answer:
Any number from 1-5
Step-by-step explanation:
Less than 6!
Answer:
72
Step-by-step explanation:
8/9 + 3/8
Multiply the denominators to get the common denominator
9x8 = 72.
Answer:
no
Step-by-step explanation:
y = 3x
Substitute the point into the equation
2 = 3*0
2 =0
This is not true so the point is not a solution
Hi!
I would approach this question by first looking at where the parallelogram is located, by graphing the image. I did so and drew a rough image on Paint (See attached image)
To get the part where the diagonals intersect, I would find the midpoint of the line between points (1, 3) and (5,-9) (or the other pair). The reason is a parallelogram's diagonals always bisect each other, meaning the point they intersect is always the middle of the two diagonals.
Therefore, you can find the midpoint of a diagonal, between (1, 3) and (5, -9). The midpoint theorem is (
.
Take the points (1, 3) and (5, -9), and fill them in.

Then solve.

(3, -3)
If you'd like to check the other midpoint:
Take the points, (8, 3) and (-2, -9)

Then solve.

(3, -3)
They're the same, so that answer is correct.
Hope this helps!
