Rewrite the equation in the slope-intercept form.
3x + y = 3
Subtracting -3x from both sides we get this:
y = -3x + 3
This is just a straight line.
Here, x can be any real number.
When x is any real number, the value of y is also any real number.
A straight line goes on forever in two directions. It really does not matter what number we select for x to find y.
Answer:
Domain is ALL REAL NUMBERS.
Range is ALL REAL NUMBERS.
Your math book may write the answer in interval notation:
Domain is (-00, 00); Range is (-00, 00).
Note:
-00 means negative infinity.
00 means positive infinity.
Still in some math books, the author(s) may decide to use set notation to express ALL REAL NUMBERS for the domain and range.
If so, we can also write the answer this way:
Domain = {x| x = ALL R}, where big R stands for real numbers.
Range = {y| y = ALL R}, where big R stands for real numbers.

Step-by-step explanation:
. 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.

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.

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
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
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).

Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).
9514 1404 393
Answer:
f, h, g
Step-by-step explanation:
The axis of symmetry for a vertically-opening parabola is the line ...
x = constant
where the constant is the x-coordinate of the vertex.
__
h(x)
The equation of f(x) is given in vertex form ...
f(x) = a(x -h)² +k . . . . . vertex: (h, k)
where (h, k) = (-4, 1).
The axis of symmetry of f(x) is x = -4.
__
g(x)
The equation of g(x) is given in standard form ...
g(x) = ax² +bx +c
The line of symmetry for this parabola is ...
x = -b/(2a) = -(-16)/(2(2)) = 16/4 = 4
The axis of symmetry of g(x) is x = 4.
__
h(x)
The x-coordinate of the vertex can be read from the graph:
x = 1
The axis of symmetry of h(x) is x = 1.
__
From smallest to largest, the rank is f(x), h(x), g(x).
25. Write the elements of the given set A A= { x|x is a square number less than 5}
1) 2
2) 4
3) 1
Answer:
A = (1, 4)
Step-by-step explanation:
Given :
Square numbers include : 1², 2², 3², 4²,...
x|x square numbers less than 5
1² = 1
2² = 4
3² = 9 (not applicable)
Square numbers less than 5 are ; 1, 4
Hence,
Set A = (1, 4) where, x|x square numbers less than 5
A = (1, 4)

Who can help me with these two?!? and can show work plz
Answer:
(4, 2 ) and (5, - 4 )
Step-by-step explanation:
(3)
6x + 2y = 28 → (1)
x = 2y → (2)
Substitute x = 2y into (1)
6(2y) + 2y = 28
12y + 2y = 28
14y = 28 ( divide both sides by 14 )
y = 2
Substitute y = 2 into (2) for corresponding value of x
x = 2(2) = 4
solution is (4, 2 )
(4)
x + y = 1 → (1)
2x + y = 6 → (2)
Rearrange (2) expressing y in terms of x by subtracting 2x from both sides
y = 6 - 2x → (3)
Substitute y = 6 - 2x into (1)
x + 6 - 2x = 1
- x + 6 = 1 ( subtract 6 from both sides )
- x = - 5 ( multiply both sides by - 1 )
x = 5
Substitute x = 5 into (3) for corresponding value of y
y = 6 - 2(5) = 6 - 10 = - 4
solution is (5, - 4 )

X + ¼ = - ⅝
Answer:
Step-by-step explanation:
Subtract 1/4 from both sides. (Change 1/4 to 2/8 so that it can be subtracted from 5/8)
X+ 1/4 = -5/8
X = -5/8 - 2/8
X= -7/8

Answer:
i think that they will get the same amount after a week's pay
Answer:
10 weeks
Step-by-step explanation:
You start by looking for the number that would help make these equal. it would have to be a number that ended with a 5 or 0. that would be 10. 10x7=70. 70+50=120
120
then 10x10=100+20
120
they will be the same at

Step-by-step explanation:
Use completing the square to solve the equation x2 - 10x = -8.
Which equation is used in the process?
x 2 - 10x + 25 = 17
x 2 - 10x + 25 = -8
x 2 - 10x - 25 = -33
Answer:
x^2 - 10x + 25 = 17
Step-by-step explanation:
x^2 - 10x = - 8
Now x^2 - 10x = (x - 5)^2 - 25, so
(x - 5)^2 - 25 = -8
(x - 5)^2 = -8 + 25
x^2 - 10x + 25 = 17..

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)
