Answer:

X=-8

Step-by-step explanation:

81^(x-4)=9^3x

(9^2)^(x-4)=9^3x

9^(2x-8)=9^3x

Same base socompare both sides

So 2x-8=3x

2x-3x=8

-x=8

X=-8

So the value of X is -8

For which value of m 4/16=m/24
vampirchik [111]
Solve for m:
1/4 = m/24
1/4 = m/24 is equivalent to m/24 = 1/4:
m/24 = 1/4
Multiply both sides of m/24 = 1/4 by 24:
(24 m)/24 = 24/4
(24 m)/24 = 24/24×m = m:
m = 24/4
24/4 = (4×6)/4 = 6:
Answer:  m = 6

The sum of three consecutive rven integers is 72. Let x represent the first integer, x+2 represent the srcond integer, and x+ 4
Vsevolod [243]

Given parameters:

First term of the sequence = x

Second term = x + 2

Third term =  x + 4

Sum of the first three terms  = 72

Unknown:

First term of the sequence = ?

Solution:

The sum of the first three terms is unknown;

            (x) + (x + 2) + (x + 4) = 72

Solve for x;

          x + x + 2 + x + 4  = 72

          3x + 6  = 72

            3x = 72 - 6

              3x = 66

                x = \frac{66}{3}   = 22

The first term of the sequence is 22

If f is translated 4 units down to create g, which function represents g? A. g(x) = f(x) - 4 B. g(x) = f(x - 4) C. g(x) = f(x +
dalvyx [7]

Answer:

g(x)=f(x)-4

Step-by-step explanation:

we are given

f is translated 4 units down to create g

we know that

whenever we translate any function by 'a' units down , we always subtract that function by 'a' units

Suppose, f(x) is translated down by 'a' units

so, we get

=f(x)-a

now, we have

f is translated 4 units down

so, we get

=f(x)-4

and it is creating g(x)

g(x)=f(x)-4
