The first one because it goes through pretty much all the points on the graph.
Answer:
6 Nickels
42 Dimes
Step-by-step explanation:
There are 48 coins in total (nickels and dimes). Let the number of nickels be "n" and the number of dimes be "d". So we can write:
n + d = 48
or
n = 48 - d
In dollars, we know nickels are worth 0.05 and dimes are worth 0.10. In total there is $4.50, so we can write:
0.05n + 0.10d = 4.50
Now replacing first equation [n = 48 - d] into 2nd, we get and equation in "d" and solve for d first:
So, there are 42 dimes.
We know from before, n = 48 - d, so
n = 48 - 42 = 6
There are 6 nickels

Answer:
115
Step-by-step explanation:
The measure of x is half the sum of the intercepted arcs. The arc on the left is a semicircle, so 180°.
The arc on the right is the difference between 180° and the two arcs shown, 60° and 70°, so is 180° -60° -70° = 50°.
Then half the sum of the intercepted arcs is ...
x° = (180° +50°)/2 = 230°/2 = 115°
x = 115
To find the contrapositive, you negate the hypothesis and the conclusion of the statement, and then switch their positions in the statement such that the conclusion becomes the hypothesis and vice versa:
If two variables are directly proportional, then their graph is a linear function.
If two variables are not directly protional, then their graph is not a linear function.
