Write the point slope form of the given line that passes through points (-4,-1) and (3,-3). Identify (x1,y1) as (-4,-1) include

Masteriza [31]

Y-y1=m(x-x1)

find slope
(y2-y1)/(x2-x1)

so
(-4,-1)
(3,-3)
slope=(-3-(-1))/(3-(-4))=(-3+1)/(3+4)=-2/7

y-(-1)=-2/7(x-(-4))
y+1=-2/7(x+4)

Find a polynomial function that has the given zeros. (there are many correct answers.) 0, 1, 6

aev [14]

Since those are the zeros, we can say that the equation would have to be
x(x-1)(x-6), then we just expand to get x^3 - 7x^2 + 6x

Two events, A and B, are independent of each other. P(A)=– and P(A and B)

Georgia [21]

Answer:

D: 0.75

$P(B) = \frac{6}{8} = 0.75$

Step-by-step explanation:

Explanation:-

Independent events:

If the occurrence of the event 'B' is not effected by the occurrence or non- occurrence of the event 'A' then the event 'B' is said to be independent of 'A'

The two events are independent if the incidence of one event is not affect the probability of other event.

P(A∩B) = P(A) P(B)

Given data A and B are independent events

Given data

$P(AnB) = \frac{1}{8} and P(A) =\frac{1}{6}$

we know that A and B are independent events are

P(A∩B) = P(A) P(B)

$\frac{1}{8} = \frac{1}{6} P(B)$

Now calculation we get

$P(B) = \frac{6}{8} = 0.75$

Final answer:-

$P(B) = \frac{6}{8} = 0.75$

Penny says that the equation x³-8=0 has only one solution x=2. Use the fundamental theorem of algebra to explain to her why she

Airida [17]

Answer:

She is incorrect

Step-by-step explanation:

The fundamental theorem of algebra states that if a polinomial has a degree n, therefore has n roots. To fidn these roots the use of complex number imay be necesary .

For the equation, degree is 3, so there are 3 solutions.
