Answer:
the third one is the one having the highest y - intercept.
reason ; the equation is of the form y = x +c
substituting the given values of y and x to get the value of c,
the first one will give c = -8
the second will give c = -1
and the third will give c = 6
Step-by-step explanation:
Hello!
As you can see, 3x+9 makes a right angle, or 90 degrees. We can turn this into an equation and solve for x.
3x+9=90
First we subtract 9 from both sides.
3x=81
Then divide both sides by 3.
x=27
Therefore, x=27.
I hope this helps!

Answer:
The two clock will chime together in 75 minutes
Step-by-step explanation:
- The two clock will chime together in the multiples of 15 and 25
- Lets find the first common multiple of 15 and 25
∵ 15 = 5 × 3
∴ The prime factors of 15 are 3 and 5
∵ 25 = 5 × 5
∴ The prime factor of 25 is 5
∴ The lowest common multiple of 15 and 25 = 5 × 3 × 5 = 75
∴ The two clocks will chime together every 75 minutes
