6a-2(a-1)
6a-2a-2
4a-2
I think it is 4a-2
For this case we must resolve the following inequality:

Adding 7 to both sides of the inequality:

Different signs are subtracted and the major sign is placed.

Thus, the solution is given by all the values of "x" less than -5.
The solution set is: (-∞, - 5)

Here we want to find the equation of the line containing the median CP.
P, being the midpoint of AB can be found using the midpoint formula as:

.
The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

.
Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

.
Answer:
She has 501 more pennies than nickles.
Answer:
Correct choice is A
Step-by-step explanation:
Consider right triangle ABC formed by the telephone pole (side AB) and ground (side BC). In this triangle AC is the length of the wire, BC is the distance from the base of the pole to the spot where the wire touches the ground and AB=15 ft, ∠ACB=42°.
Then
