The answer is -3. Now imagine a line of numbers from -4 to +4. Your first number in that line would be +2. From there you would be moving to the left since you're taking numbers away and in this case you're taking away +5. So when you're going on that line from +2 tho the left by +5 it gets you to -3. I hope you understand what I'm trying to say:D I also included the photo of that "line".

A line that includes the points (0,w) and (–1,2) has a slope of 6. What is the value of w?
mars1129 [50]

Answer:

8

Step-by-step explanation:

slope =  \frac{w - 2}{0 - ( - 1)}  \\  \\  \therefore \: 6 =  \frac{w - 2}{0 + 1} \\  \\  \therefore \: 6 =  \frac{w - 2}{1}  \\  \\ \therefore \:w - 2 = 6 \\  \\  \therefore \:w = 6 + 2 \\  \\  \therefore \:w = 8\\  \\

Beth gets a sum of 5 when she rolls two fair number cubes. What is the probability that one of the fair number cubes is a 1?
ira [324]

Using it's concept, it is found that there is a 0.5 = 50% probability that one of the fair number cubes is a 1.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The outcomes of the pair of cubes that result in a sum of 5 are as follows:

(1,4), (2,3), (3,2), (4,1).

Of those 4 outcomes, 2 involve a number 1, hence the probability is given by:

p = 2/4 = 0.5.

Find the value of c so that the polynomial p(x) is divisible by (x-3). p(x) =-x^3+cx^2-4x+3. c=?
Vilka [71]

Answer:

\boxed{\textsf {The value of c is $\sf \dfrac{-14}{3}$. }}

Step-by-step explanation:

A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,

\sf \implies p(x)=- x^3+cx^2-4x+3

And the factor is ,

\sf \implies g(x) = x + 3

Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0

\sf \implies p(x)= - x^3+cx^2-4x+3 \\\\\implies\sf p(-3) = 0 \\\\\sf\implies -(-3)^3+c(-3)^2-4(-3)+3 = 0 \\\\\sf\implies 27 + 9c +12+3=0 \\\\\sf\implies 9c +42=0 \\\\\sf\implies 9c = (-42) \\\\\sf\implies c = \dfrac{-42}{9}\\\\\sf\implies \boxed{\pink{\sf c = \dfrac{-14}{3}}}

<h3><u>Hence </u><u>the </u><u>value </u><u>of </u><u>c </u><u>is </u><u>(</u><u>-</u><u>1</u><u>4</u><u>)</u><u>/</u><u>3</u><u> </u><u>.</u></h3>
