Answer:
(0, -8)
Step-by-step explanation:
The distance must be equal from C to A and points B to D.
Answer:
and
Step-by-step explanation:
First of all, even if the system is of 4th degree, by looking at the shape of the equations I am expecting up to 2 solutions.
The easiest way to solve it, since both equation are in the form y= something, is to equate both RHSs.
which tells us that either or
Now we can replace these value of x in one of the two to finish our work:
Answer:
80/99
Step-by-step explanation:
When the repeat starts at the decimal point, put the digits over an equal number of 9s.
This fraction cannot be reduced.
Answer:
choice 3
Step-by-step explanation:
9/12 simplified = 3/4. 6/8 simplified =3/4
so they are the same
Answer:
69 degrees
Step-by-step explanation:
<u>1) Find x</u>
The angles measured x degrees and (x-28) degrees have a sum of 180 degrees because straight lines always have a measure of 180 degrees. Knowing this, construct the equation:
Add 28 to both sides
Divide both sides by 2
Therefore, x is equal to 104 degrees.
<u>2) Find the measure of the (x-28) degree angle</u>
Plug x into x-28
Therefore, the measure of this angle is 76 degrees.
<u>3) Find y</u>
All the interior angles in any triangle will add up to 180 degrees. Knowing this, we can construct another equation:
Open up the parentheses
Subtract both sides by 75
Divide both sides by 3
Therefore, y is equal to 35 degrees.
<u>4) Find the measure of the (2y-1) degree angle</u>
Plug y into 2y-1
Therefore, y is equal to 69 degrees.
I hope this helps!
