Given f(x) =3x -1 and g(x) = 2x-3, which value of x does g(x)=f(2)

X=4 because if f(2)=3x-1 that means that x=2 will replace x in the equation so 3(2)=6 6-1=5.Then both need to equal to 5 so you need to do the he reverse of equations 5+3=8 and 2x=8 and 8÷4=2. I know I didnt explained quite perfectly but I know x=4.

f(x) = 3x - 1

g(x) = 2x - 3

g(x) = f(2)

g(x) = 3.2 - 1

g(x) = 6 - 1

g(x) = 5

If g(x) = 5, then, 2x - 3 = 5

2x - 3 = 5

2x = 5 + 3

2x = 8

x = 8/2

x = 4

So,

f(2) = g(4)

Multiple-Choice The average distance

murzikaleks [220]

Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).

If you do $\frac{meters}{meters/second}$ , your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!

If y varies directly as the x^2 and y = 200 when x = 5, what is the value of y when x = -3?

gayaneshka [121]

As the variation is direct we have:
$y = kx ^ 2
$
We must find the value of k.
For this, we use the following data:
y = 200 when x = 5
Substituting values we have:
$200 = k5 ^ 2
$
Clearing k:
$k = 200/5 ^ 2

k = 200/25

k = 8$
Then, the function is:
$y = 8x ^ 2
$
We evaluate the function for x = -3
$y = 8 (-3) ^ 2

y = 8 (9)

y = 72$
Answer:
the value of y when x = -3 is:
c.
72

Mae has a number cube with 6 sides that are numbered 1 through 6. What is the probability that Mae will roll an odd number?

Stels [109]

Answer:

C) $P(E) = \frac{3}{6}$

The probability that Mae will roll an odd number

$P(E) = \frac{3}{6}$

Step-by-step explanation:

Step(i):-

Given that Mae has a number cube with 6 sides that are numbered 1 through 6.

n(S) = { 1,2,3,4,5,6,} = 6

Let 'E ' be the event of odd numbers

Mae will roll an odd number

n(E) = {1, 3, 5} = 3

Step(ii):-

The probability that Mae will roll an odd number

$P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}$

$P(E) = \frac{3}{6}$
