Answer:
y=\frac{4x}{5}-5
Step-by-step explanation:
linear equation
y=mx+b
We can see that when x=0 y= -5
THis means that b= -5 so we have
y=mx-5
We then know that when x=5 y= -1 so we have
-1=5m-5
Solve this and get m= 4/5
So we have
Answer:
70
Step-by-step explanation:
You have to use ratios. If 5 of 12 members bought water, then x of 168 members will buy water.

70 members will buy bottled water.
8x+1=x-6
7x+1=-6
7x=-7
X=-1
Y=x
Y=-1
Answer:
5 laps
Step-by-step explanation:
30 ÷ 6 = n
n=5
Answer:
That's incorrect. The simplest way to show this is by evaluating the functions at a given point. Let's say x=0, then:
Sin(-x) = Sin(0) = 0
-cos x = -cos (0) = -1
Therefore, Sin(-x)≠-cos x.
