So, if you're trying to solve an equation, here's an example:
2x + 4y = 8
You would minus 2x from both sides. (you want to get the equation into a mx + b format)
4y= -2x + 8
you would now divide both sides by 4
y = -1/2x + 2
So now that your equation is in y = mx+b, you should know your answer.
mx= to slope
b= y-intercept
so, therefore, your y-intercept is 2.
Answer: 136 m
Step-by-step explanation:
For first interval,
Time = 2 hours 40 minutes = ![2+\dfrac{40}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=2%2B%5Cdfrac%7B40%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 18 m/h
Distance = 
[Formula : Distance=Speed x time]
For second interval,
Time = 1 hour 50 minutes = ![1+\dfrac{50}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=1%2B%5Cdfrac%7B50%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 24 m/h
Distance = 
Total distance = 48 m +88 m = 136 m
Hence, he went 136 m.
Combine like terms in Qx + 12 = 13x + P:
x(Q-13) = P-12
P-12
Then x = ----------
Q-13
Note that Q may not = 13. But none of the answer choices present Q = 13.
Let's go thru the answer choices one by one.
P-12
x = ----------
Q-13
-24
Check out A: Q=12 and P= -12: x = -------- = 24 This is OK (ONE sol'n)
-1
-25
Check out B: Q = -13 and P = -13: x = ----------- = 25/26 OK
-26
13-12
Check out C: Q = -13 and P = 13: x = ------------ = -1/26 OK
-13-13
12-12
Check out D: Q = 12 and P = 12: x= ---------- = 0 OK
12-13
It appears that in all four cases, the equation has ONE solution.
Answer:
-2
Step-by-step explanation:
y/x=constant
3/24=y/(-16)
y=-2
It is 4/15 im pretty sure ,
