Answer:
18
Step-by-step explanation:
The diagonals of a parallelogram <em>bisect</em> each other, which is to say they split each other in half, and since each half length is equal to the other, we can say that
3x + 3 = 6x - 57
Which, after some algebraic manipulation, gives us the solution
x = 18.
Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
-n + 11/6 = 7/9
-n = 7/9 - 11/6
-n = -19/18
n = 19/18
Answer: 15 pongs you say?
Step-by-step explanation:
Mapping the triangle on one another simply means you use rigid transformations, which involve scaling. So the second triangle is congruent.
Since 3 is the shortest side, 27 pairs with three, so:
27/3 = 9
The second triangle is 9 times larger.
Using this we can do:
5 * 9 = 45
6 * 9 = 54
since 6 is the largest side, 54 is our answer! Or is it?
Note that this is a right triangle, so we use the Pythagorean theorem to find the hypotenuse.
= 
so 9*sqrt(34) is our answer
The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]
The range are the possible output values of f(x)
We need to solve f(x) = 3.2x for each value in our domain
f(-4) = 3.2(-4) = -12.8
f(-2) = 3.2(-2) = -6.4
f(0) = 3.2(0) = 0
f(2) = 3.2(2) = 6.4
f(4) = 3.2(4) = 12.8
