The range of the function will be;
⇒ {1, 4, 16}
What is Domain?The set of all inputs of the function is called Domain of set.
Given that;
The function is,
⇒ y = 3/4x + 7
And, The domain = {-8, 4 , 12 }
Now,
Since, The function is,
⇒ y = 3/4x + 7
And, The domain = {-8, -4 , 12 }
We know that;
The range of the function is the value of y.
Hence, It is find as;
The function is,
⇒ y = 3/4x + 7
Put x = - 8,
⇒ y = 3/4 (-8) + 7
⇒ y = - 6 + 7
⇒ y = 1
Put x = 4,
⇒ y = 3/4 (-4) + 7
⇒ y = - 3 + 7
⇒ y = 4
Put x = 12,
⇒ y = 3/4 (12) + 7
⇒ y = 9 + 7
⇒ y = 16
Thus, The range = {1, 4, 16}

how to simplify numbers
Answer:
Simplify means to make smaller or more simple.
Step-by-step explanation:
You need to make the number which needs to be simplified into a number lower than the original number.
For example:
"4" would simplify to "2"
beace half of 4 is 2. This could further be simplifed as "1" is half of 2.
so if there was a fraction:
4/8
the numerator would simplify to 1 and the denominator would simplify to 2 because whatever you do to the top you must do to the bottom. The numerator stops simplifying at 1 and the denominator stops simplifying at 2
so
4/8 = 1/2
Sarah hired a painter to paint her bedroom walls and ceiling. Each of the four bedroom walls is 18 ft. Long and 8 ft. High. Two walls each have one door, and both doors measure 3 ft. By 7 ft. One wall has a window that is 3 ft. By 5 ft. The doors and window do not have to be painted. A gallon of paint can cover 300 ft.2. A hired painter claims that he will need three gallons to paint the one room. Is the estimate correct?
Answer:
The estimate is not correct?
Step-by-step explanation:
Given data
Area of wall = 18*8
=144ft^2
=4*144
=576ft^2
Area of doors
=3*7
=21ft^2
=2*21
=42ft^2
Area of window
=3*5
=15ft^2
Hence the total surface area of the room
=576-42-15
=519ft^2
The amount of paint needed= 519/300= 1.73
Approximately 2 gallons
We are told that 1 gallon will cover 300ft^2
Hence 3 gallons will cover 300*3= 900ft^2
Therefore the painter overestimated the amount of paint needed
As 2 gallons will do the job
Solve the equation 2 = -6 – 20x for x.
Answer:
x = - 2/5
Step-by-step explanation:
1.) add six on both sides, the six on the right will cancel out
2.) divide both sides by -20
3.) this will cancel the -20 on the right out which will give your answer for x on the left side
therefore, x should equal - 2 / 5 once simplified

. CDEF is a trapezium
. ABCF is a rectangle
. BD = 9cm
. AB = 6cm
. EF = 3cm
. perimeter of ABCF = 20cm
9514 1404 393
Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².

Michael takes a sip of water every 20 minutes while playing soccer. He took his first sip at 3:05. When did he take his sixth sip?
Answer:
Michael took his 6th sip at 4 : 05
Step-by-step explanation:
Duration in which Michael takes a sip of water = 20 minutes
Therefore, he will take his sixth sip after (20 × 6) = 120 minutes Or after 2 hours
If he takes first sip of water at 3 : 05
Then he will take his sixth sip at ( 3 : 05 + 2 : 00)
Time at his sixth sip = 5 : 05
Delilah deposits $8,255 in an account that pays 4.2% simple interest. How much money will be in her account after 8 years?
A.$2,773.69
B.$11,028,68
C.$12,254,66
D.$27,736,80
Answer:
$11,028.68
Step-by-step explanation:
As we all know, the simple interest formula is as follows:
[tex]P(1+rt)[/tex]
Wherein:
P = Principal amount
r = rate (in percentage so, rate/100)
t = time (in years)
Hence, when we substitute in these values,
[tex]8255(1+(4.2/100)*8)[/tex]
= $11,028,68
it will be 4.2/100 as it is percentage form.
Solve for x. Round to the nearest tenth, if necessary.

A farmer harvested 1,760 pieces of fruit. 65% of them were not oranges. How many oranges did the farmer harvest?
Answer:
Number of oranges= 616
Step-by-step explanation:
Giving the following information:
A farmer harvested 1,760 pieces of fruit. 65% of them were not oranges.
To calculate the number of oranges, we need to use the following formula:
Number of oranges= total number of fruits*percentage of oranges
Number of oranges= 1,760 * (1 - 0.65)
Number of oranges= 616
25 points to 50 points find the percent of change
Answer:
The percent of change 200%.

Answer:
1.1 Solve x-3y+7 = 0
recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y+7 = 0 and calculate its properties

Answer: Solution: (-4, 1)
Step-by-step explanation:
x = 3y - 7
4x + 5y = -11
Substitute x for 3y - 7
4x + 5y = -11
4 (3y - 7) + 5y = -11
12y - 28 + 5y = -11
17y - 28 = -11
Add 28 to both sides
17y = 17
y = 1
x = 3y - 7
x = 3(1) - 7
x = 3 - 7
x = -4
Solution: (-4, 1)
Solve the system of linear equations. 2x + 6y = -3 2x + 6y = 0 Ο Α (0, 2) infinitely many solutions C (9,7) no solution
Answer:
Step-by-step explanation:
-3 = 2x+6y
2x+6y = 0
By transitivity, -3 = 0, a contradiction. No solution.
If you graph the lines, you will see they are parallel, therefore never intersect.
What is the equation of the line with a slope of 2 through (-4, 6) in point-slope form?
O y = 2x + 14
Oy-6 = 2 (x +4)
Oy= 2x – 14
Oy+6 = 2 (x – 4)
Answer:
y - 6 = 2(x + 4)
Step-by-step explanation:
Point slope form is y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex]).
[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that they give you in the problem, which is (-4, 6), and m is the slope, which is 2.
When you plug everything in, you should get
y - 6 = 2(x + 4).
