You need to get rid of -6 by adding 6, you also need to add 6 to 18.

4x = 24

Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24

x = 6

So the value of x is 6

Hope this helps! :)

Answer: X=6

Step by step explanation:
First you want to add 6 to 18 and you get 24
2nd: so the equation is 4x=24
3rd: you want to divide 4 to both sides
4th: 4 divided by 4 =1 and 24 divided 4= 6
So.. X=6

What function represents the pattern shown in the table?
Pavlova-9 [17]

Given:

The table of values of an exponential function.

To find:

The function for the given table of values.

Solution:

The general exponential function is:

y=ab^x        ...(i)

Where, a is the initial value and b is growth factor.

From the given table it is clear that the function passes through the points (1,9) and (2,36). It means the function must be true for these two points.

9=ab^1        ...(ii)

36=ab^2       ...(iii)

On dividing (iii) by (ii), we get

\dfrac{36}{9}=\dfrac{ab^2}{ab}  

4=b  

Putting b=4 in (ii), we get

9=a(4)^1

\dfrac{9}{4}=a

Putting a=\dfrac{9}{4},b=4 in (i), we get

y=\dfrac{9}{4}(4)^x

y=9(4)^{x-1}

The function notation with variable n is:

f(n)=9(4)^{n-1}

Therefore, the correct option is D.

A system of equations is graphed on the coordinate plane.
ANTONII [103]
You have 2y=3x-1 and 4y=6x-2. first step is to get the y by itself . first equation you divide everything by 2 which gives you the equation: y= 3/2x-1/2
or y= 1.5x-.5, for the second equation you divide everything by 4, which gives you y=6/4x-2/4 (1/2) or y=1.5-.5. both equations are equal to one another: 
the answer is therefore C Infinitely many solutions.

Please help me idk this
Sergio [31]
First take the fractions and find their common denominator:
\frac{1}{2} x 4 =\frac{4}{8}

Now you can add the fractions:
\frac{4}{8} + \frac{1}{8} = \frac{5}{8}

Now add your whole numbers and the fraction:
1+1= 2 >> 2+\frac{5}{8} = 2\frac{5}{8} yards

Now subract 2\frac{5}{8} from 5:
5-2\frac{5}{8} =2\frac{3}{8} yards
