timama [110]3 years ago
4 0

Answer:

9

Step-by-step explanation:

Get the equation into the form y = mx + c

3x + y - 9 = 0

y = -3x + 9

The y intercept is 9

Write the equation for a line that has an initial value of 3 and 3/4 as it’s rate of change
frutty [35]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

initial value of 3, namely when x = 0, y = 3, so we have the point (0 , 3) and it has a rate or slope of 3/4.

(\stackrel{x_1}{0}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{3}{4} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{\cfrac{3}{4}}(x-\stackrel{x_1}{0})\implies y=\cfrac{3}{4}x+3

Please help emergency
Firdavs [7]

Step-by-step explanation:

This is a probability related problem.

  Probability is the likelihood of an event to occur;

    Pr = \frac{number of possible outcomes}{Total sample space}

The sample space here is from 1 to 25 which is 25

A.

Pr of a card marked 8; we have just 1 possible outcome;

       Pr(8)  = \frac{1}{25}

B.

Pr  of drawing a card that is a multiple of 5;

    Multiples of 5 = 5, 10, 15 and 25

     Pr (multiples of 5) = \frac{4}{25}

C.

Pr of drawing a card with odd numbers:

          Number of odd numbers between 1 and 25  = 13

     Pr(odd numbers) = \frac{13}{25}

D.

Pr of drawing a number with square number on it;

        Square numbers between 1 and 25  = 1, 4, 9, 16 and 25

  Pr(square numbers) = \frac{5}{25}   = \frac{1}{5}

Consider the line y=9x-1.
OLEGan [10]

Step-by-step explanation:

Slope=9

i)

y−y1=m(x−x1)

When line is parallel

y+5=9(x-6)

y+5 = 9x - 54

<h3>59 = 9x-y </h3>

When line is perpendicular

y+5=-1/9(x-6)

9(y+5)= -1(x-6)

9y + 45 = -x+6

<h3>x+9y = -39</h3>
