1 answer:

5 0

X turns positive anywyere you do it

to graph it
graph x=y for all x≥0
now reflect that line across y axis
you get a v
move that whole graph 7 units down

done

Answer:

4 minutes 5 seconds

Step-by-step explanation:

Without additional information, we have to assume that one sequence can begin immediately after another, and that each takes the same amount of time. The total time for 7 sequences is 7 times the time for one sequence.

7 × 35 seconds = 245 seconds = 4 minutes 5 seconds

There are 60 seconds in a minute.

The value of x in the equation 4^(2x+5)=8^(3x)

Roman55 [17]

4⁽²ˣ ⁺ ⁵⁾ = 8³ˣ

But 4 = 2² and 8 = 2³

4⁽²ˣ ⁺ ⁵⁾ = 8³ˣ

2²⁽²ˣ ⁺ ⁵⁾ = (2³)³ˣ

Multiply out the powers, also since the

2⁴ˣ ⁺ ¹⁰ = 2⁹ˣ

Since the bases are the same, hence the powers are also the same.

4x + 10 = 9x

4x - 9x = -10

-5x = -10

x = -10/-5

x = 2

Hope this explains it.

mafiozo [28]

Answer:

2/9

Step-by-step explanation:

If you meant you want to find U,

1) Divide both side by 2. -> U = 4/9 divided by 2

2) You get U = 4/18, which you can further simplify by dividing 2 on top and bottom to get 2/9
