Answer: C
Step-by-step explanation: 8 (1/3) 16 (2/3) 24 (3/3)
Answer:
y=3x-2 (d)
Step-by-step explanation:
First, we need to look at the y-intercept, we can see that when x = 0, y= -2. So then our equation has to be y=mx+b, and b is -2. next we find our slope, we can see that we go up by 3, then over 1, so our slope is 3/1 or 3. so the final equation is y=3x-2.
Hope this helps!

Assume r= t not sure if you mistyped this.
t = 15 min
T(t) = 68 (0.5)^(15/10) = 24 Celsius
31 = (0.5)^(t/10) take ln
ln31 = (t/10) ln (0.5) + ln68
t = (ln32 - ln 68/ln0.5) * 10 = 11.3 min
Let start with making equation to find how much your friend’s lunch cost.
19= 3+x Let x= the cost of your friend’s lunch
19-3=3+x-3
16=x
Answer: Your friend’s lunch is $16.
