What is the equation of the line that passes through (0, -2) and has a slope of 0? NEED HELP ASAP!!

1 answer:

8 0

The equation is y= -2.
How? If you recall, a linear equation is y= mx+b. The m is the slope (growth) and b is the y-intercept ( where the line crosses the y-axis).

Now since there is no slope or m, the equation would look like this:
y= b or y= 0+b

Next, you want to input the coordinator points (0, -2) into the equation. reminder: (x, y) = x=0 y= -2

y= 0+ -2
y= -2

And there you go! The equation is y= -2. I hope I help you in solving this problem, if not message me, because I'll be glad to help you.

pogonyaev

Answer:

9 cookies per dollar

Step-by-step explanation:

This is a fraction equal to

36 cookies ÷ 4 dollars

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 4

36 cookies ÷ 4

--------------------------

4 dollars ÷ 4

9 cookies

---------------

1 dollar

9 cookies

-----------------

dollar

= 9 cookies per dollar

3.5 hours: $10 1/2 hour: $1.25. which is the better deal

3.5 hours: $10 because if a 1/2 hour equaled 1.25 : 3.5 hours would give you $7.75

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer:

z = -0.4.

Step-by-step explanation:

Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement $x$ of a normal random variable $X \sim N(\mu,\; \sigma^{2})$ :

$\displaystyle z = \frac{x-\mu}{\sigma}$ ,

where

$z$ is the z-score of this measurement,
$x$ is the value of this measurement,
$\mu$ is the mean of the random normal variable, and
$\sigma$ is the standard deviation (the square root of variance) of the random normal variable.

Let the length of a trout in this lake be $X$ inches.

$X \sim N(30, \; 4.5^{2})$ .

$\mu = 30$ , and
$\sigma = 4.5$ .

For this measurement, $x = 28.2$ . Apply the formula to get the z-score:

$\displaystyle z = \frac{x - \mu}{\sigma} = \frac{28.2 - 30}{4.5} = -0.4$ .

Divide<br> -0.0328 0.002<br> What is the quotient?<br> Enter your answer in the box.

Marina86 [1]

The quotient is -16.4

$\frac{-0.0328}{0.002}$

Apply the fraction rule: $\frac{-a}{b}=-\frac{a}{b}$ $=-\frac{0.0328}{0.002}$

Divide the numbers: $\frac{0.0328}{0.002}=16.4$ $=-16.4$

The quotient rule is a calculus technique for determining the derivative or differentiation of a function that is represented as a division or ratio of two differentiable functions.

Therefore, we can apply the quotient method to get the derivative of a function of the form f(x)/g(x), where f(x) and g(x) are both differentiable functions and g(x) ≠ 0. The quotient rule immediately follows the product rule and the notion of limits of derivation in differentiation.
