Assume f(x) = g(x). Which of the following two functions may be used to represent the function 3x = x – 4? *

1 answer:

8 0

Since we know that the two functions are equal, f (x) = g (x), therefore when we equate the two equations the result should be similar to 3x = x – 4:

A. f(x) = 3x, g(x) = x – 4

Equating the two functions:

3x = x – 4 (correct)

So we now got our answer (A)

What is 49.6 divided by 7.8?

fomenos

Answer: 6.4

Step-by-step explanation: If rounding to one decimal place, your answer would be 6.4.

49.6 divided by 7.8 = 6.35897435...

Now, we see that after the 3 (The first decimal place) there is a five. Because we are rounding to the first decimal place the second decimal place will tell us to round up or down. In this case because it's a five, we would round up.

Which Expression is Equivalent to the given expression? (4m^2n)^2/2m^5n

Daniel [21]

Answer:

D. $8 {m}^{ - 1} n$

Step-by-step explanation:

$\huge \frac{(4 {m}^{2} n)^{2} }{2 {m}^{5}n } \\ \\ \huge= \frac{16 {m}^{4} {n}^{2} }{2 {m}^{5}n } \\ \\ \huge = 8 {m}^{4 - 5} {n}^{2 - 1} \\ \\ \huge \purple{ \boxed{= 8 {m}^{ - 1} n}}$

Un automóvil corre a 120 kilómetros por hora y otro a 80 kilómUetros por hora; si deben recorrer 960 kilómetros, ¿con cuántas ho

Artist 52 [7]

Answer:

4 hours

Step-by-step explanation:

The speed of the first car is

$v_1 = 120 km/h$

While the speed of the second car is

$v_2=80 km/h$

The time it takes for each car to cover a distance d is

$t=\frac{d}{v}$

where

d = 960 km is the total distance covered

For car 1, the time taken is:

$t_1=\frac{960}{120}=8 h$

For car 2, the time taken is:

$t_2=\frac{960}{80}=12 h$

Therefore, the difference in time is:

$\Delta t =t_2-t_1 =12 -8 = 4 h$

What are the coordinates grapging x=3 and y=-2x+1

marusya05 [52]

Answer: -5

First, coordinates are (x, y). You’re x is 3, so all you need to do it plug in x into your algebraic equation to find y. Then just plug both into (x, y) and you have your coordinates.

y=-2(3)+1
y=-6+1
y=-5
