Answer:

Slope of given line = \frac{-9}{4} and slope of perpendicular line = \frac{4}{9}

Step-by-step explanation:

We are given a line -9x - 4y = 5 .

We have to find the slope of a line parallel to this line and also a line perpendicular to this line.

Let the general equation be ax + by = c.

Then the slope of this line = \frac{-a}{b} = \frac{-9}{4}

The slope of a line perpendicular to a line is the negative inverse of the slope  of the line. Using this concept,

Slope of line perpendicular to the given line = \frac{b}{a} = \frac{4}{9}

fgiga [73]

Answer:

<u>x-intercept</u>

The point at which the curve <u>crosses the x-axis</u>, so when y = 0.

From inspection of the graph, the curve appears to cross the x-axis when x = -4, so the x-intercept is (-4, 0)

<u>y-intercept</u>

The point at which the curve <u>crosses the y-axis</u>, so when x = 0.

From inspection of the graph, the curve appears to cross the y-axis when y = -1, so the y-intercept is (0, -1)

<u>Asymptote</u>

A line which the curve gets <u>infinitely close</u> to, but <u>never touches</u>.

From inspection of the graph, the curve appears to get infinitely close to but never touches the vertical line at x = -5, so the vertical asymptote is x = -5

(Please note:  we cannot be sure that there is a horizontal asymptote at y = -2 without knowing the equation of the graph, or seeing a larger portion of the graph).

A board is 48 in long. It must be divided into 4 pieces of equal length, and each cut will cause a waste of 3/16 in. How long wi
NISA [10]

Answer:

12 pieces

Step-by-step explanation:

Total length of the board = 48 in

It must be divided into 4 pieces of equal length

This means, there will be 3 cut to have 4 pieces

Each cut will cause a waste of 3/16 in.

Total waste = 3 cut × 3/16 in

= (3*3)/16

= 9/16 in

Length of board remaining = Total length of the board - Total waste

= 48 - 9/16

= (768-9)/16

= 759/16 in

How long will each piece be after the cuts are made?

Length of each piece after the cut = Length of board remaining / 4

= 759/16 ÷ 4

= 759/16 × 1/4

= 759/64

= 11.859375

Approximately 12 pieces to the nearest whole number

Find x if f(x)=2x+7 and f(x)=-1
Natalija [7]

Answer:

x = -4

Step-by-step explanation:

~~~~~~f(x) = -1\\\\\implies 2x +7 = -1\\\\\implies 2x = -1 - 7\\\\\implies 2x = -8 \\\\\implies x = -\dfrac 82 \\\\\implies x = -4
