Select the equation that is equivalent to the equation: y+6=-4(X-2)

First, you gotta distribute the -4 to x-2,

<span>y+6=-4(X-2)
y+6=-4x+8

Then, subtract both sides by 6,
y+6-6=-4x+8-6
y=-4x+2

Done</span>

How to simplify an expression with a negative exponent

svetlana [45]

Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have $2^{-3}$

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .

$\frac{1}{2^{3} }$

$2^{3}$ simplifies into 8. So, the result is

$\frac{1}{8}$

Hope this helps! Please mark as brainliest, thanks!

The intercepts and the graph on your worksheet are not correct. Please see below for details:

$x^2-2x-3=0$ has solutions at x=-1 and x=3 (use the quadratic formula to solve). That means these are the x-intercepts, namely points:

(-1,0) and (3,0).

The y-intercept comes from setting x=0 and calculating the y value:

$y=0^2-2\cdot0-3=-3$

so the y-intercept is (0,-3).

Now to the graph: Based on the form of the function we can see this is a quadratic function and its graph will be a parabola. You can reformat the expression in the following form

$y = x^2-2x-3=(x-1)^2-4$

and that will indicate that the apex of the parabola (open up) will be at the point (1,-4).

Knowing the apex, the x intercepts, and the y intercept, we can graph it now.

Graph is in the image attached.

suppose you know that over the last 10 years, the porbabiliy that your town would have at least one ma jor stor was 40%. describ

Anuta_ua [19.1K]

Answer:

The probability of a big storm is 40%.

Now, you can find a D10 (a die with 10 faces)

You can assign 4 numbers (0, 1, 2, 3) to the event "there is a major storm"

in this way, you have 40% of having a storm.

and the other 6 numbers (4, 5, 6, 7, 8, 9) to the event "there is not a major storm". This means that we have 60% of not having a storm.

now, when you roll the dice you can see if a year there will be a storm or not.

Now, you roll the dice 5 times (for the 5 years) and take note of the results and the number of storms in those 5 rolls.

Now do the same thing a bunch of times, at least 25 times.

Now, you recorded the results in each set of rolls, now see the number of sets that have at least years with storms.

Take that number and divide it by the total number of sets of data (in this case 25, for example)

The result is the probability that we are looking for.
