How would you graph y=| x-2|-4

1 answer:

4 0

To graph ty function simply make a table of values, where you choose any value for x and substitute that value in the function.

Then take the absolute value of the expression in the square bracket.

It is always positive, the absolute value of -6 is 6 etc.

Then graph the resulting points.

Another way to do it is simply draw the graph of y = |x| then move it 2 spaces to the right and 4 spaces down, I believe.

A study found that the average stopping distance of a school bus traveling 50 mph was 264 feet. a group of automotive engineers

lutik1710 [3]

Answer:

Step-by-step explanation:

Given that a study found that the average stopping distance of a school bus traveling 50 mph was 264 feet.

Sample taken showed the following results

$n=40\\\bar x =262.3 feet\\Std dev = \sigma= 3 ft$

Since population std deviation is known and sample size is large, z test can be used.

$H_0: \bar x=264\\H_a: \bar x$

(Left tailed test)

Mean difference = $264-262.3 = 1.7$

Std error = $\frac{\sigma}{\sqrt{n} } \\=\frac{3}{\sqrt{40} } \\=0.474$

Z = test statistic = mean diff/std error

= $\frac{1.7}{0.474} \\=3.584$

p value = 0.00017

Since p < alpha our 0.05 we reject null hypothesis

There is evidence to show that mean is less than 264 feet

(Assumptions:

Sample are randomly drawn

Sample represents the population

Solve this equation, and show step by step: y=-5/2x-5

KengaRu [80]

Let's solve for x.y=−52x−5Step 1: Flip the equation.−52x−5=yStep 2: Add 5 to both sides.−52x−5+5=y+5−52x=y+5Step 3: Divide both sides by (-5)/2.−52x−52=y+5−52x=−2y−105Answer:x=−2y−105

A student is running a 3-kilometer race. He runs 1 kilometer every 2 minutes. Select the function that describes his distance fr

stepladder [879]

Distance from finish line can be computed by subtracting the amount he has ran from 3. Every minute he runs .5km, and we can use this to create a function to describe this instance.
$y = 3- .5x$
The distance remaining is equivalent to the minutes multiplied by .5km for each minute subtracted from 3 which is the total distance.
