Answer:

2. 4x = 7x - 21

Step-by-step explanation:

4x = 7(x - 3) \\ 4x = 7x - 21 \\ 21 = 7x  - 4x \\ 21 = 3x \\  \frac{21}{3}  = x \\ 7 = x \\

xeze [42]

Answer:

speed greater than 0.08 mi/min

Step-by-step explanation:

given data

distance = 2 mi

time = 25 min

to find out

the distance you travel and your speed  and time related

solution

we know that distance is

distance = speed × time     ...............1

so at park at most 25 min

so we need time = \frac{distanec}{speed} \leq 25

so here

we know

\frac{2}{25} \leq speed

so

0.08 \leq speed

so we can say that he need to run at speed greater than 0.08 mi/min

Anyone good at this?? Please help me. I attempted at this and I don’t think my answer is correct!
AnnZ [28]

Answer:

A

Step-by-step explanation:

There are two ways you could do this question. You could graph it with something like Desmos or you could put a couple of x values in for f(x). I'll do the latter first. When you understand it, try putting it into Desmos.

f(x) = (3/4)^x

f(0) = (3/4)^0

f(0) = 1  

=======

f(x) = (3/4)^x

f(1) = 3/4

=========

g(x) = (3/4)^x - 6

g(0) = (3/4)^0 - 6

g(0) = 1 - 6

g(0) = - 5

========

g(x) = (3/4)^x - 6

g(1) =  (3/4)^1 - 6

g(1)= 3/4 - 6

g(1) = -5 1/4

Conclusion

It looks like the graph has shifted down 6.
