Answer:

0.71 percent, or \frac{5}{7}

Step-by-step explanation:

There are 7 letters in a bowl.

However, two of them are both A.

So, out it would be \frac{2}{7} for the probability that you WOULD choose them.

\frac{5}{7} for your problem.

For the function f(x)=ax^3+bx^2-5x+9, determine the values of a and b so that f(-1)=12 and f'(-1)=3
Alecsey [184]

If

<em>f(x)</em> = <em>ax</em> ³ + <em>bx</em> ² - 5<em>x</em> + 9

then

<em>f '(x)</em> = 3<em>ax </em>² + 2<em>bx</em> - 5

Given that <em>f</em> (-1) = 12 and <em>f</em> '(-1) = 3, we get the system of equations

-<em>a</em> + <em>b</em> + 5 + 9 = 12

3<em>a</em> - 2<em>b</em> - 5 = 3

or

-<em>a</em> + <em>b</em> = -2

3<em>a</em> - 2<em>b</em> = 8

Multiply through the first equation by 2 and add it to the second one to eliminate <em>b</em> and solve for <em>a</em> :

2(-<em>a</em> + <em>b</em>) + (3<em>a</em> - 2<em>b</em>) = 2(-2) + 8

-2<em>a</em> + 2<em>b</em> + 3<em>a</em> - 2<em>b</em> = -4 + 8

<em>a</em> = 4

Substitute this into the first equation above to solve for <em>b</em> :

-4 + <em>b</em> = -2

<em>b</em> = 2

A line has a slope of -2 and a Y intercept of -3. Graph the line using the slope and y-intercept. Which of the following points
nikdorinn [45]
<h2>Greetings!</h2>

Answer:

(1.5 , 0) , (-6 , 9) , (3 , -9)

Step-by-step explanation:

First, you need to find the equation of the line, which is:

y = mx + c

Where m is the gradient (or slope) and c is the y-intercept. Simply replace these values with the one given to you:

y = -2x -3

Now, simply draw this line by finding two points,

x = 0

y = -2(0) - 3

y = -3 when x = 0

When x = 3

y = -2(3) - 3

y = -9 when x = 3

Now you can use these points to plot the graph. (attacthed a screenshot of it)

Now simply find which given co-ordinates fit on the line. The points on the line are:

(1.5 , 0) , (-6 , 9) , (3 , -9)


<h2>Hope this helps!</h2>
