Answer:
Infinitely many.
Step-by-step explanation:
3x + 2y = 4
-6x - 4y = -8
Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.
Hint: angle y is adjacent to an angle of 90 degrees adjacent angles add up to 180 degrees
3250
You will need to Multiply 10x325
To find the median of a data set order all the numbers from least to greatest, then find the number in the middle. If there are two numbers in the middle find the mean of the two numbers.
90 52 78 64 67 88 68 75 75 78 ← given
52 64 67 68 75 75 78 78 88 90 ← ordered l to g
75 and 75 are the two numbers in the middle, and since they are the same that means 75 is our median.
D) 75 is your answer.
9x-y = 45
Move 9x to the other side. Sign changes from +9x to -9x.
9x-9x-y=45-9x
-y=45-9x
Multiply both sides by -1
(-1)(-y)=y
(-1)(45)=-45
(-1)(-9x)
y=-45+9x or y=9x-45
Answer: y=-45+9x or y=9x-45
