y=-3x-6(-3,2)Write the equation of a line parallel to the given line and passing through the given point

1 answer:

8 0

Slope of required equation = slope of given line = -3( since both lines are parallel). By slope point form, y - y1 = m( x - x1). y-2 = -3(x-(-3)). y-2 = -3x - 9. y = -3x - 7. Required equation is y= -3x - 7.

1. To find the x-intercept, replace y in the equation with 0, then solve for x.

... To find the y-intercept, replace x in the equation with 0, then solve for y.

If the equation is easily put into the form

... x/a + y/b = 1

Then the x-intercept is "a" and the y-intercept is "b".

2. Let's graph 3x+4y = -12.

If we divide the equation by -12, we can put it into the form

.. x/(-4) + y/(-3) = 1

This equation has x-intercept -4 and y-intercept -3.

(If you know the intercepts, you can simply draw the line through them to graph your linear equation.)

Suppose that the functions r and s are defined for all real numbers x as follows.

mixas84 [53]

ANSWER

Given

$r(x) = x - 1$

and

$s(x) = 3 {x}^{2}$
ANSWER TO QUESTION 1

$(r + s)(x) = r(x) + s(x)$

$(r + s)(x) = x - 1 + 3 {x}^{2}$

$(r + s)(x) = 3 {x}^{2} + x - 1$

ANSWER TO QUESTION 2

$(r \times s)(x) = r(x) \times s(x)$

$(r \times s)(x) = (x - 1) \times 3 {x}^{2}$

$(r \times s)(x) = 3 {x}^{3} - 3 {x}^{2}$

ANSWER TO QUESTION 3

$( r - s)(x) = r(x) - s(x)$

$( r - s)(x) = x - 1 - 3 {x}^{2}$

$( r - s)( - 3) = (- 3) - 1 - 3 ({ - 3}^{2} )$

$( r - s)( - 3) = - 4 - 3 \times 9$

$( r - s)( - 3) = - 4 - 27 = - 31$
