The equation for the absolute value function is y = -2lx-4l + 2
An absolute value function is what?
A function that surrounds an algebraic expression in absolute value symbols is called as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value. The definition of the absolute value parent function is given as follows: f(x)=x if x>00 if x=0 if x0.
Y=a| x+h |+k is the form of the equation for an absolute value function. Also:
The graph's vertex is (h,k).
The range of the graph is y≥k for a>0 and its domain is a set of all real numbers.
The range of the graph is y≤k when a0, and its domain is a set of all real numbers.
X=h is the symmetry axis.
If a>0, it opens up; if a0, it opens down.
The graph of y=a| xh |+k can be created by translating the line graph y=| x | by h units horizontally and k units vertically.
If | a | 1 and if | a | >1, the graph of y=a| x | is wider than the graph of y=| x | and narrower.
So here (h,k)=(4,2)
range of y≤2
and its narrower so a≥1
hence the equation is y = -2 l x-4 l +2

Answers
The net disadvantage of purchasing the high-speed wheel grinder is $ 5,750
What is net advantage or disadvantage?
Net advantage or disadvantage is the total of potentially monetary savings from action of a business choosing to purchasing or lease an asset.
First, we calculate the net advantage in year 0
= current salvage value of standard - Original cost of high-speed
= $ 11,750 - $ 67,500
= - $ 55,750
Next we calculate the net advantage in year 5
= net advantage in year 0 + cost saving in 5 years
= - $ 55,750 + ($ 26,750 - $ 11,750) * 5
= - $ 55,750 + $ 50,000
= - $ 5,750

of a that represents the total amount that Hudson paid at the register.
Answers
If Hudson having a discount coupon of 20% off, wants to buy an item having a printed price of "x" dollars, and a 5% tax is added to the discounted price in the end, then the expression that can represent the final amount Hudson paid for the item will be [(4x/5) + (x/25)].
As per the question statement, Hudson goes to a store an buy an item that costs "x" dollars, with the intention of using his 20% flat discount coupon, and then, a 5% tax is added to the final discounted price.
We are required to determine an expression that can represent the final amount Hudson paid for the item as per the above case.
Since Hudson gets a discount of 20% over the cost price of his desired item, the discounted cost price of the item becomes, [x - {(20/100) * x}]
= [x - {(1/5) * x}]
= [x - (x/5)]
= (4x/5).
And then, a 5% tax is added to the final discounted price, which takes the final amount to [(4x/5) + {(5/100) * (4x/5)]
= [(4x/5) + {(1/20) * (4x/5)]
= [(4x/5) + (x/25)]
= (21x/25)

The interior angles of the second triangle will be 50°, 55°, and 75° respectively.
What are similar triangles?
If the corresponding angles and sides of two triangles are congruent, then the two triangles are said to be similar.
In other words, similar triangles have the same shape but may differ in size.
Given, a triangle has interior angles of 50°, 55°, and 75° with side lengths of 3.1 m, 3.2 m, and 4.0 m.
And, a second triangle has side lengths of 10.3 m, 10.5 m, and 12.0 m.
The corresponding sides of both triangles are 3.1 m, 3.2 m, and 4.0 m with 10.3 m, 10.5 m, and 12.0 m respectively.
Then, the angles of both triangles are also corresponding to each other.
So we get, the interior angles of the second triangle will be 50°, 55°, and 75° respectively.

The solution to the variable x is 12 and the measure of ∠B is 48°.
How to solve congruent angles?∠A = 5x−12°
∠B = 2x+24°
Angle A and Angle B are congruent angles.
Congruent angles are angles with the same or equal measures.
So,
∠A = ∠B

x = 12
So therefore,
∠A = 5x−12°

= 60 - 12
= 48°
∠B = 2x+24°

The slope of a line is the tangent of the angle that the line makes with the positive direction of the x-axis. It signifies the rise in the y-variable for a unit change in the x-variable.
If the line passes through the points (x, y) and (x, y), then the slope of the line, m = (y - y)/(x - x).

She begins at sea level, which is an elevation of 0 feet.
She travels straight down for 41 seconds at a speed of 4.9 feet per second.
She then ascends for 49 seconds at a speed of 3.2 feet per second.
After this 90-second period, how much time, in seconds, will it take for the scientist to travel back to sea level at 3.6 feet per second?
Answers
The scientist will take 23 seconds to get back to the sea level.
Let us calculate the distance covered by the scientist at the given speeds and at the specified times.
She travels down for 41 seconds at speed of 4.9 feet per second.
Distance travelled = 41 × 4.9 = 200.9 feet
Elevation = -200.9 feet
She then goes up for 49 seconds at speed of 3.2 feet per second.
Distance travelled = 49 × 3.2 = 156.8 feet
Elevation = -222.9 + 156.8 = -44.1
So she is at a depth of 44.1 feet below the sea level.
Time taken = 44.1 / 3.6 = 12.25 seconds
Therefore it will take her about 12.25 seconds to go back to the sea level.
