Answer:
f(x)=9
Step-by-step explanation:
Answer:
y=0x+2 meaning the slope is equal to 0
Step-by-step explanation:
If you think about this question you'll see that our two points have the same y coordinate
This means that the slope is equal to 0
so we have
y=0x+b
If we plug in -3 for x and set the equation equal to 2 we can find b
0+b=2
b=2
so we have
0x+b=y

Answer:
A. 2.8 billion years old
Step-by-step explanation:
1/16 = (1/2)^4, so 4 half-lives have elapsed.
4 · 0.700 billion years = 2.8 billion years
The rock is 2.8 billion years old.
Rewrite the first equation: 3y=-2x-17. The equations are coincidental and -17 is one sixth of -102 so the other coefficients need to be multiplied by 6: 18y=-12x-102.
Answer:
8.5 min
Step-by-step explanation:
Here, distance = rate times time. The rate is 10 in/min, and so
d = (10 in/min)t.
If the snail travels 85 in, then 85 in = (10 in/min)t, and we solve for t as follows:
t = (85 in) / (10 in/min) = 8.5 min
