Answer:

\Huge \boxed{x=51}

\rule[225]{225}{2}

Step-by-step explanation:

\displaystyle \frac{x-3}{4} =12

Multiplying both sides by 4.

\displaystyle \frac{x-3}{4} *4=12 *4

x-3=48

Adding 3 to both sides.

x-3+3=48+3

x=51

\rule[225]{225}{2}

Answer:

x = 51

Step-by-step explanation:

(x-3) /4 = 12

Multiply each side by 4

(x-3) /4 *4 = 12*4

x-3 = 48

Add 3 to each side

x-3+3 = 48+3

x = 51

Solve 4e^2x-3=12 please help
Anestetic [448]

4*e^{2x} -3 = 12

Step 1:

Here we have -3 in subtraction on the left side, so when we take it to the right we apply opposite operation of subtraction that is addition.

4*e^{2x} = 12+3

4*e^{2x} = 15

Step 2:

Next we have 4 in multiplication on left side, so dividing right side by 4,

e^{2x} = 15/4

e^{2x} = 3.75

Step 3:

taking log on both sides

ln ( e^{2x}) = ln(3.75)

{2x} =ln 3.75

Step 4:

Dividing right side by 2,

x= ln (3.75) /2 = 0.66088

Answer : x = 0.66088..

please help 30 points !! in a proportional relationship when Y=2 when X=8 Which of the following equations would describe this r
Alex777 [14]

Answer:

(1)

Step-by-step explanation:

We will try:

(1) y = \frac{1}{4}x => 2 = 2 (seems legit)

(2) y = 4x => 2 = 32 (nope)

(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)

(4) y = \frac{1}{2}x - 2 => 2 = 2 (like the above)
