9x - 4y = 7
-4y = -9x + 7
y= 9/4x - 7/4

slope of perpendicular line = -4/9
slope of parallel line = 9/4

Well if you change it to standard form, you get y=9/4x+7/4. The important part of that is 9/4x. If a line is perpendicular, the slopes are opposite. The slope of a perpendicular line would be -4/9x, don't forget the negative. And a parallel line has the same slope so any line with 9/4 is parallel but if the line has the same b value it is coinciding, not parallel and those aren't the same.

Divide to find two equivalent fraction 4/12
SCORPION-xisa [38]

Answer: 2/6 and 1/3

Step-by-step explanation: Equivalent fractions are fractions that have the same value but have different top and bottom numbers.

We can find 1 equivalent fraction by dividing the numerator and the denominator by 2 and we get 2/6. We can also reduce 2/6 by dividing the numerator and the denominator by 2 and we get 1/3.

So two equivalent fractions for 4/12 would be 2/6 and 1/3.

13. Jessica has taken 8 quizzes. The mean of her scores is 92. Her first 6 scores are shown.
Dovator [93]

Answer: Median= 91; 8th quiz score=86

Step-by-step explanation: The sum of the scores is 8×92=736. Subtract the 6 given scores and then a 100 for the seventh quiz to find the score she got on the 8th quiz, this is an 86. Now that you have all the scores, arrange them all in the least to greatest order and find the average of the middle two numbers (median), which is 91!
