To begin, distribute the -2 to both the 3x and the 2, which would result in -6x-4. When added back into the original equation, you have 7-6x-4. 7-4 is 3, so the final answer is -6x+3.

Which of the following represents the equation of the line passing through (-4,5)

Sergio [31]

Answer:

Answer: y=2x+13.

Step-by-step explanation:

Your input: find the equation of the line perpendicular to the line y=5/2−x/2 passing through the point (−4,5).

The equation of the line in the slope-intercept form is y=5/2−x/2.

The slope of the perpendicular line is negative inverse: m=2.

So, the equation of the perpendicular line is y=2x+a.

To find a, we use the fact that the line should pass through the given point: 5=(2)⋅(−4)+a.

Thus, a=13.

Therefore, the equation of the line is y=2x+13.

Answer: y=2x+13.

Verizon [17]

The answer is: "40 cm " .
_________________________________________________________
<u>Note</u>:
_________________________________________________________

$\frac{200 ft }{ (x) cm} = \frac{5}{1}$ ;

Solve for "x" (in "cm" ) ;

→ 5x = 200 * 1 ;

→ 5x = 200 ;

Divide each side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 5x / 5 = 200 / 5 ;

to get:

→ x = 40 .

The answer is: " 40 cm " .
