Answer:
The answer is 1/9.
Step-by-step explanation:
When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.
First take the number and flip the reciprocal, in this case -9 turns into -1/9.
Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9
Therefore the answer is 1/9.
Her car had 14.46 gallons of fuel before her trip because 12.86+1.6=14.46
Answer:
116 degrees
Step-by-step explanation:
Answer:
The slope of the line given by the equation -3x=30-5y is .
Step-by-step explanation:
-3x=30-5y
Move the -3x to the right side of the equal sign and the -5y to the left.
5y=30+3x
By switching them to opposite sides, their sign changes from - to +.
Then, divide both sides by 5 in order to isolate the y.
You get:
<em>y= </em><em />
According to y=mx+b, mx refers to the slope.
In this case, the slope would be .
The answer is 21/6
Explanation: the next number in the pattern would be 21 since this is linear
