6.find the interval(s) where the graph is increasing
7. find the interval(s) where the graph is decreasing
8.find the interval(s) where the graph is positive
Answer:
I dont think you need the answer anymore, the question is from ages ago
Step-by-step explanation:
The absolute value function has a domain of all real numbers, a range of non-negative real numbers, a single x-intercept at (0, 0), no y-intercept, a constant rate of change of 1 over the interval [-1, 4], and is increasing for x greater than 0 and decreasing for x less than 0. Overall, the graph is positive over the entire real number line.
1. Domain:
The domain of a function is the set of all possible input values (x-values) for which the function produces a real output value (y-value). In the case of the absolute value function, the output is always real, so the domain is all real numbers. Therefore, the domain is:
(x) ∈ (-∞, ∞)
2. Range:
The range of a function is the set of all possible output values (y-values) that the function produces. The absolute value function always outputs a non-negative value, so the range is:
(y) ∈ [0, ∞)
3. x-intercepts:
The x-intercepts of a function are the points where the graph of the function crosses the x-axis. This happens when the output value (y) is zero. In the case of the absolute value function, the output is zero only when the input (x) is zero. Therefore, the x-intercept is:
(0, 0)
4. y-intercepts:
The y-intercept of a function is the point where the graph of the function crosses the y-axis. This happens when the input value (x) is zero. In the case of the absolute value function, the output is always non-negative, so there is no y-intercept.
5. Rate of change on |-1,4|:
The rate of change of a function at a point is the slope of the line tangent to the graph of the function at that point. The absolute value function is a piecewise function, so it has different slopes in different intervals. Over the interval |-1, 4| , the function is simply x + 1, so the rate of change is 1.
6. Intervals where the graph is increasing:
The graph of the absolute value function is increasing over the intervals where the expression inside the absolute value bars is positive. In other words, the graph is increasing when x > 0. Therefore, the interval where the graph is increasing is:
(x) ∈ (0, ∞)
7. Intervals where the graph is decreasing:
The graph of the absolute value function is decreasing over the intervals where the expression inside the absolute value bars is negative. In other words, the graph is decreasing when x < 0. Therefore, the interval where the graph is decreasing is:
(x) ∈ (-∞, 0)
8. Intervals where the graph is positive:
The graph of the absolute value function is always non-negative, so it is positive over the entire interval:
(x) ∈ (-∞, ∞)
The midpoint CD of is E(-1,0) . One endpoint isC (5, 2) .
What are the coordinates of the other endpoint?
For this case we have that by definition, the midpoint formula is given by:
[tex](\frac {x_ {1} + x_ {2}} {2}, \frac {y_ {1} + y_ {2}} {2}) = (x_ {m}, y_ {m})[/tex]
We have to:
[tex](\frac {5 + x_ {2}} {2}, \frac {2 + y_ {2}} {2}) = (- 1,0)[/tex]
So:
[tex]\frac {5 + x_ {2}} {2} = - 1\\5 + x_ {2} = - 2\\x_ {2} = - 2-5\\x_ {2} = - 7[/tex]
On the other hand:
[tex]\frac {2 + y_ {2}} {2} = 0\\2 + y_ {2} = 0\\y_ {2} = - 2[/tex]
Finally we have to:
[tex]D (-7, -2)[/tex]
Answer:
[tex]D (-7, -2)[/tex]
Answer: The required co-ordinates of the other endpoint D are (-7, -2).
Step-by-step explanation: Given that the midpoint CD of is E(-1,0) . One endpoint is C(5, 2) .
We are to find the coordinates of the other endpoint D.
Let (x, y) represents the co-ordinates of the point D.
We know that the co-ordinates of the midpoint of a line segment with endpoints (a, b) and (c, d) are given by
[tex]\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]
So, according to the given information, we have
[tex]\left(\dfrac{5+x}{2},\dfrac{2+y}{2}\right)=(-1,0)\\\\\\\Rightarrow \dfrac{5+x}{2}=-1\\\\\Rightarrow 5+x=-2\\\\\Rightarrow x=-2-5\\\\\Rightarrow x=-7[/tex]
and
[tex]\dfrac{2+y}{2}=0\\\\\Rightarrow 2+y=0\\\\\Rightarrow y=-2.[/tex]
Thus, the required co-ordinates of the other endpoint D are (-7, -2).

Explanation:
To find the area of a rectangle, you multiply the length by the width. For a rectangle with a length of 1/12 ft and a width of 3/4 ft, you would calculate the area as follows:
Area = length × widthArea = (1/12) ft × (3/4) ftArea = 3/48 ft²Area = 1/16 ft²Thus, the area of the rectangle is 1/16 square feet.
3. Your car gets 30 mpg on the highway. If gas costs $4.20 per
gallon, how much does it cost to drive your car per mile?
Answer:
It costs $0.14 to drive your car for one mile.
Hope this helps :)
To calculate the cost of driving per mile, the price of gasoline ($4.2) should be divided by the car's fuel efficiency (30 mpg). This results in a cost of $0.14 per mile.
Explanation:To find out how much it costs to drive per mile, we need to divide the cost of one gallon of gas by the number of miles that can be driven with that gallon. In this case, the cost of gasoline is $4.20 per gallon and the mileage of the car is 30 miles per gallon.
First, identify the cost of gas per gallon and the car's fuel efficiency (miles per gallon). Here, the cost is $4.2 and efficiency is 30 mpg.Next, you should divide the cost per gallon by the miles per gallon. Therefore, $4.20 ÷ 30 = $0.14, which represent the cost per mile.
So, in this scenario, it costs approximately $0.14 to drive your car for one mile on the highway.

the vet put 2 litters of kittens in a cage with 5 other kittens she also put 3 litters of puppies in the cage next door with one other puppy if all the litters have the same number of animals and the cages now contain the same number of animals how many animals are in each litter
answer:
10
Step-by-step explanation:
if u add 5+3+2 that will equal 10
Each litter contains 4 animals.
Explanation:To find the number of animals in each litter, we need to use the given information. We know that the vet put 2 litters of kittens in a cage with 5 other kittens, so there are a total of 7 kittens in the first cage. In the second cage, there are 3 litters of puppies with 1 other puppy, so there are 4 puppies in the second cage. Since the cages now contain the same number of animals, we can set up an equation: 2 litters of kittens + 5 other kittens = 3 litters of puppies + 1 other puppy. Substituting the given numbers, we have 2x + 5 = 3x + 1, where x represents the number of animals in each litter. Solving this equation, we find that x = 4. Therefore, each litter contains 4 animals.

A shipment of 8 computers contains 4 with defects. Find the probability that a sample of size 1, drawn from the 8, will not contain a defective computer. What is the probability that a sample of 1 of the 8 computers will not contain a defective computer?
Answer:
0.5
Step-by-step explanation:
Total computers in the shipment = 8
Number of computers with defects = 4
We have to find if the sample size of 1 is drawn from the 8 computers, what is the probability that it will not contain a defective computer.
Drawing a sample size of 1 is equivalent to selecting 1 computer on random. So, in short we have to find the probability of randomly selecting a computer which is not defective.
Since, out of 8 computers, 4 are defective, so, the remaining 4 will be without defects.
Probability is defined as ratio of favorable outcomes to total number of possible outcomes.
Possible outcome here is any of the 8 computers. So number of possible outcomes is 8.
Favorable outcome is selecting the computer without defect. So, number of favorable outcomes = 4
Thus, the probability of selecting a computer without defect = 4/8 = 0.5
The probability of drawing a non-defective computer from a sample size of 8, with 4 being defective, is 0.5 or 50%.
Explanation:The question is asking for the probability that a single computer from a shipment of eight will not be defective. With 4 defective computers out of 8, we know that the other 4 are not defective. The total number of outcomes when drawing one computer is 8. We are interested in the events where the drawn computer is not defective. As there are 4 such computers, there are 4 successful outcomes.
So, to find the probability, we construct a ratio of successful outcomes (not defective computers) to total outcomes (all computers). That would be 4 over 8, or 0.5, meaning there is a 50% chance that if you draw one computer, it will not be defective.

Find the slope of the segment with the endpoints (1, − 1/n ) and ( n/m , − 1/m ).
(y - yo) = m.(x - xo)
Let's go
(-1/n - (-1/m)) = s.(1 - n/m)
(-1/n + 1/m) = s.(1 - n/m)
(-m+n)/mn = s.(m - n)/m
If we multiply both sides by m
(-m + n)/n = s.(m - n)
If we take the (-1) from the left side we have
(-1.(m - n))/n = s.(m - n)
And if we divide both sides by (m - n)
-1/n = s
So our slope is -1/n
18. Convert 9.268 to a fraction, the 6 and 8 are repeating

Answer: (4,7)
To find the ordered pair (x, y) that satisfies the given equations y=3x-5 and y=1/2x+5, we can solve the system of equations simultaneously. The ordered pair is (4, 7).
Explanation:To find the ordered pair (x, y) that satisfies the given equations y=3x-5 and y=1/2x+5, we need to solve the system of equations simultaneously. By setting the two expressions for y equal to each other, we can find the x-coordinate. Substituting this value back into either equation will give us the y-coordinate.
Let's set 3x-5 equal to 1/2x+5:
3x-5 = 1/2x+5
Multiplying through by 2 to eliminate the fraction:
6x-10=x+10
Combining like terms:
5x=20
Dividing both sides by 5:
x=4
Substituting this value of x into y=3x-5:
y=3(4)-5
y=12-5
y=7
