Answer:

Yes.

Step-by-step explanation:

$f\left(x\right)=-3x+2$

$f\left(-1\right)=-3(-1)+2$

$y=f(-1)=5$

The domain of this function is all Real numbers $\:\left(-\infty \:,\:\infty \:\right)$

$\{x \in \mathbb{R}: -\infty \:$

Which equation represents an exponential function that passes through the point (2, 36)?

Zepler [3.9K]

Answer: It would be the first equation because:

Step-by-step explanation:

In order to be an exponential function, the X

variable has to be in the exponent, that eliminates

the second and fourth answers

f(X) = 4(3)X

using the point (2,36)

f(2) = 4 (3)2

= 4 (9 )

= 36

Write an equation in point-slope form of the line that passes through (-4,1) and (4,3).

Step2247 [10]

Answer:

An equation in point-slope form of the line that passes through (-4,1) and (4,3) will be:

$y-1=\frac{1}{4}\left(x+4\right)$

Step-by-step explanation:

Given the points

(-4,1)

(4,3)

Finding the slope between the points (-4,1) and (4,3)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-4,\:1\right),\:\left(x_2,\:y_2\right)=\left(4,\:3\right)$

$m=\frac{3-1}{4-\left(-4\right)}$

Refine

$m=\frac{1}{4}$

Point slope form:

$y-y_1=m\left(x-x_1\right)$

where

m is the slope of the line

(x₁, y₁) is the point

in our case,

m = 1/4

(x₁, y₁) = (-4,1)

substituting the values m = 1/4 and the point (-4,1) in the point slope form of line equation.

$y-y_1=m\left(x-x_1\right)$

$y-1=\frac{1}{4}\left(x-\left(-4\right)\right)$

$y-1=\frac{1}{4}\left(x+4\right)$

Thus, an equation in point-slope form of the line that passes through (-4,1) and (4,3) will be:

$y-1=\frac{1}{4}\left(x+4\right)$

Determine whether the following probability experiment represents a binomial experiment and explain the reason for your answer.

allochka39001 [22]

Answer:

No. See explanation below.

Step-by-step explanation:

Since the cards are being selected <u>without replacement,</u> every time we select a card, <u>the probability varies</u> (since there is one less card) and therefore, the probability doesn't remain the same for every trial and therefore, the probability of success changes for every trial.

It is because of this that this probability experiment doesn't represent a binomial experiment.
