Evaluate the piecewise function for the given values of x by
matching the domain values to the range values.
Answer:
For x = -4f (x) = x + 2
We evaluate the value of x = -4
f (-4) = (-4) + 2
f (-4) = -2
Answer is : f (-4) = -2For x = 4f (x) = -2x + 4
We evaluate the value of x = 4
f (4) = -2 (4) +4
f (4) = -8 + 4
f (4) = -4
Answer is : f (4) = -4For x = 0f (x) = 3x -4
We evaluate the value of x = 0
f (0) = 3 (0) -4
f (0) = 0-4
f (0) = -4
Answer is : f (0) = -4The value of the function at x = 1 is, f(x) = - x - 4 which equals f(1) = - 3.
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Similarly, A piecewise function can also be in terms of without modulus.
Given, f(x) = - x - 4 for x < 3.
f(x) = x² - 7, for 3 ≤x < 12.
f(x) = (120/x) + 5, for x ≥ 12.
Now, At x = 1, It satisfies,
f(x) = - x - 4 for x < 3.
Therefore, f(1) = - (-1) - 4.
f(1) = - 3.

Step-by-step explanation:
The quadratic formula is
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$.[/tex]
where a is the coefficient of x squared, b is the coefficient of x, and c is a regular number.
Here, we have
a = 1
b = 7
c = 16
Plugging in values, we have
[tex]\frac{-7 +\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]
and
[tex]\frac{-7 -\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]
The first equation solves to an i term, so there is no way that there is an answer.
The second equation is also an i term, meaning there are no solutions to this equation

A ball is thrown in the air. The path of the ball is represented by the equation h=-t^2+8t, where t represents time in seconds and h represents the height of the ball in meters.
What is the maximum height of the ball?
How long is the ball in the air for before it hits the ground?
Answer:
a) 16 meters ; b) 8 seconds
Step-by-step explanation:
The function can be represent with a parabola whose vertex is its maximum point
for answer the first question we have to find the y of the vertex
first of all we have to find the x
Vertex (x) = -b/2a = -8/-2 = 4
if we substitute t with 4, we can find the y
Vertex (y) = -(4^2) + (8*4) =
= -16 + 32 = 16
so the answer is 16 meters
for answer the second question we have to find where the parabola intercepts the x axis, that means solve the associated equation:
-t^2 + 8t = 0
t^2-8t = 0
t(t-8) = 0
t = 0
t = 8
the parabola intercept the x axis in (0,0) and in (8,0)
if we find the distance between this two points we can answer to the question
8-0 = 8 seconds

A state university has an annual tuition of $12,000. Bradley would like to attend this university and will save money each month for the next 4 years. His grandparents will give him $2,800 for his first year of tuition. Which plan shows the minimum amount of money Bradley must save to have enough money to pay for his first year of tuition?
Answer:
$767 per month for the next 4 years
Step-by-step explanation
first it’s minus the 2800 they gave him and that’s 9,200 then divided by the amount of months in a year which is 12 you end up with 766.6 but rounded that would be the closest answer and then when you multiply 767x12 it’s 9200 plus the 2800 it’s 12,000 which means it checks out.
Tuition for one year at state technical institute is about 4200. Josh would like to attend this institute and will save money for each month for 4 years. His parents will give him 1500 for his first years tuition. What’s the minimum amount of money josh must save to have enough money to pay for Josh’s first year of tuition?
Answer: pretty sure it’s $56.25
Step-by-step explanation:
4200-1500= 2700 divided by 48 months (4 years).

Translation can be accomplished by reflecting across two parallel lines. The amount of translation is double (twice) the distance between the lines. Any two lines with the same spacing will give the same translation.
Here, the translation is 4 up and 4 right. The amount by which each point is translated is 4√2 units in the direction "northeast", that is, along a line with a slope of 4/4 = 1.
Any line of reflection is a perpendicular bisector of the segment joining the original point and its image. This means we need to identify two lines that have a slope of -1 and that are separated by (4√2)/2 = 2√2 units.
The attachment shows that two lines with this slope that have a separation of 2√2 will have y-intercepts that differ by 4. (The lines shown happen to be the correct answer choices.)
The offered choices of lines have y-intercepts of {5, 6} and {10, 12}. The only pair of lines with y-intercepts that differ by 4 are y=-x+6 and y=-x+10.
_____
Additional comment
We have made sort of a qualitative argument for the correct answer. If you like, you can say that the two lines of reflection each cause the image to be located halfway to its destination. That mean, for example, for point R(2,2), the first image point is R'(4,4). The line of reflection, as we said above, is the perpendicular bisector of this. It will have a slope of -1 and go through the point (3, 3), so its equation is ...
y -3 = -1(x -3) ⇒ y = -x +6
Similarly, the second (final) image point is R''(6,6). We can find the other line of reflection to be one that has a slope of -1 and goes through the point (5, 5). Its equation is ...
y -5 = -1(x -5) ⇒ y = -x +10
These are two of the equations that are offered as answer choices, so should be selected.
As we said at the beginning, any lines with this spacing will do. We cannot presume at the start that each line of reflection will move the image half the distance.
Beth says 20-5x3 is 45, pat says 20-5x3 is 5. who is right?
Answer:
Pat is right
Step-by-step explanation:
first multiply/divide then add/subtract,
Beth: 20 - 15 = 45 => 5 ≠ 45
Pat: 20 - 15 = 5 => 5 = 5
Answer:
Pat
Step-by-step explanation:
There is only one correct answer. To find it, you must follow the correct order of operations.
There is a subtraction and a multiplication. There are no parentheses.
The rule is that you must do the multiplication before the subtraction.
20 - 5 * 3 =
= 20 - 15
= 5
In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.
The correct answer is 5, and Pat is correct.

The perimeter of a rectangle is 14cm. The length of the rectangle is 4 cm more than twice the width. Find the dimensions of the rectangle.
Answer:
length = 6 cm
width = 1 cm
Step-by-step explanation:
l = length
w = width
l = 4 + 2w
2(4 + 2w) + 2w = 14
8 + 4w + 2w = 14
8 + 6w = 14
6w = 6
w = 1
find length:
l = 4 + 2(1)
l = 6

Step-by-step explanation:
Answer:
2004 cubic inches
Step-by-step explanation:
Looking at the figure, there seems to be a chunk missing from the front. Since the overall length is 15 inches, and the length near the missing chunk is 12, then the missing length is 3. If that chunk was filled in, this would have been a 17 * 15 * 8 rectangluar prism. That would have been 2040 cubic inches. (120 * 17) However, a 3 by 8 by 3 triangular prism is missing.
1/2(3 * 8 * 3)
1/2(24 * 3)
1/2(72)
36
Now, subtract 36 from 2040.
2040 - 36
2004 cubic inches
2004 cubic inches of gas will fill this gas can.

Avery threw a football 60 yards,how many meters is that
Answer:
54.9 meters
Step-by-step explanation:
Given: Avery threw football 60 yards
To find: How high it is in meters
Solution: Simply convert 60 yards to meters, by doing that, find out how many meters are in one yard
1 = 0.9144
Multiply the result by 60
60 × 0.9144 = 54.86
Then, round it to the nearest tenths; 54.9
Avery threw the football 54.9 meters high
