If 3x / 4 = 7 - x / 3, then x = what?

Alja [10]

$\frac{3x}{4} = 7-\frac{x}{3} 

$
$\frac{3x*3}{4*3} = \frac{7*12}{12} -\frac{x*4}{3*4} 

$
$\frac{9x}{12} = \frac{84}{12} -\frac{4x}{12}$
$12*( \frac{9x}{12} = \frac{84}{12} -\frac{4x}{12} )$
$9x=84-4x
$
$13x=84$
$84/13$

Through: (-5, -5), slope=2/5

kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

$y = mx + b$

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: $m = \frac {2} {5}$

Thus, the equation is of the form:

$y = \frac {2} {5} x + b$

We substitute the given point and find "b":

$-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3$

Finally, the equation is:

$y = \frac {2} {5} x-3$

Answer:

$y = \frac {2} {5} x-3$

Which of the following is the value of f(3) in the function below? f(x)=2x-1

Dmitry_Shevchenko [17]

Answer:

F(3) = 2 * 3 - 1, which is 6 - 1 equaling 5.

Step-by-step explanation:

3 times 2 is six since you have to follow PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction). Multiplication is before Subtraction, and that is why we multiply 2 and 3 first, since 3 replaces the variable x. After multiplying 2 and 3 to get 6, subtract by 1 to get 5.

Answer: 5
