poizon [28]

Answer:

A ) 0.2 ( x + 15) = 5

Step-by-step explanation:

$0.2 ( x + 15 ) = 5$

$\frac{0.2 (x + 15)}{0.2} = \frac{5}{0.2}$

$x +15=25$

$-15$ $-15$

$x=10$

find the equation of a straight line passing through the point (3,3) which is perpendicular to the line y=-1/2x-4

Mars2501 [29]

Answer:

y = 2x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{1}{2}$ x - 4 ← is in slope- intercept form

with slope m = - $\frac{1}{2}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{1}{2} }$ = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, 3) into the partial equation

3 = 6 + c ⇒ c = 3 - 6 = - 3

y = 2x - 3 ← equation of perpendicular line
