Answer:
1. 9/10
2. 14/15
3. 1 1 /6 or 7/6
Step-by-step explanation:
1. Change the 5, the denominator to 10. 8/10
then add to 1/10 8/10 + 1/10= 9/10
2. Change both denimnators to 15. You will then get 9/15 and 5/15.
Add them together and get 14/15
3. Change both denominators to 6 and you will get 3/6 and 4/6.
Add them together to get 7/6.
If you want to make it into a mixed fraction it would be 1 1/6 (as in one and one-sixth)
Answer:
y = -1/3x + 2
Step-by-step explanation:
The gradient of the given line is 3 because (y = mx +c where m is the gradient)
Therefore, to find the gradient of the perpendicular line (at 90 degrees), you need to find the negative reciprocal.
The negative reciprocal of 3 is -1/3 because imagine if 3 = 3/1, to get the reciprocal, you flip it, and to get the negative, you just flip the sign.
Now we know that Line M is y = -1/3x + c, we need to find the y-intercept.
To do this, just input the point (3,1) into y = -1/3x + c, to get c. This is because we know (3,1) is on the line from the question.
So it would be 1 = (-1/3 x 3) +c
Which would be 1 = -1 +c
And so c = 2
Put everything together and you get y = -1/3x + 2
