20min/1hr
40min/1hr
Question order asks ratio from outside time to inside time so the 40 would come first. also, all the above are correct. You can write a ratio as a fraction, with a colon, or with the word to.
Y=-x+8
gradient of the parallel line is the same as the gradient of the line given, which is -1
to find the y-intercept, sub the values (9,-1) into the equation we are finding which is y=-x+c
B is the answer to your question
Answer:
(1)
(2)
Step-by-step explanation:
Solving (1):
Considering
We have:
This gives:
Solve for a
So:
To solve for b, we make use of Pythagoras theorem
This gives

Take LCM and solve
Take square roots
Solving (2):
Considering
We have:
This gives:
Solve for a
So:
To solve for b, we make use of Pythagoras theorem
This gives
Collect like terms
Take square roots
Answer:
y=2/3x+19/3
Step-by-step explanation:
Use this equation y-y1=m(x-x1) and plug the numbers in
