How many solutions exist for the system or equations graphed below
Answer:
One
Step-by-step explanation:
The solutions to a system of equations are where the lines intersect. This system will only ever intersect once, therefore there is only one solution. You can see the solution at the top right.
The number of solutions that exists for the given system of equations is one.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Given a graph of a system of equations.
The graph consists of two lines. So they are linear functions.
A system of linear equations can have one or infinitely many solutions and no solutions at all.
Solution of a system is the intersection point of the graph.
Here there is only one intersection point.
Hence the number of solutions is 1.

If a function is defined by the formula y=1/2x + 3 and its domain is given by the set {-4,0,8}, then which of the following sets gives the function's range?
Answer:
y = {1, 3, 7}
Step-by-step explanation:
Given
y = ½x + 3
Domain: {-4, 0, 8}
Required
Determine the range of the function
To do this, we simply substitute each value of the domain in the given expression
We start with the first
Substitute -4 for x in y = ½x + 3
y = ½ * -4 + 3
y = -2 + 3
y = 1
Then 0
Substitute 0 for x in y = ½x + 3
y = ½ * 0 + 3
y = 0 + 3
y = 3
Lastly, 8
Substitute 8 for x in y = ½x + 3
y = ½ * 8 + 3
y = 4 + 3
y = 7
Hence, the range of the function is:
y = {1, 3, 7}

One-third of a number is 12.
Work out one-half of the number.
Answer:
18
Step-by-step explanation:
If 12 is one-third of a number, to find the number, we have to multiply 12x3, which equals 36. To find one-half of 36, divide 36/2, which equals 18.
Hope this helped you!! Have a wonderful day C:
The fraction of one-half of the number such that one-third of it is 12 will be 18.
What is a fraction?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, the fraction is the division of the two numbers but the division is not wholly complete.
Suppose that number is x.
One-third = (1/3)x
It is equal to 12 so,
(1/3)x = 12
x = 36
Now one-half of 36 will be (1/2)36 = 18
Hence "The fraction of one-half of the number such that one-third of it is 12 will be 18".

Q4: Write the equation in slope-intercept form of the line that is perpendicular to
the graph of each equation and passes through the given point.
y = -5x + 1; (2, -1)
Answer:
5y = x + 11
Step-by-step explanation:
Given parameters:
Equation of the line ;
y = -5x + 1
Coordinates = (2, -1)
Find the equation of a line perpendicular;
Solution:
A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.
Equation of a straight line is expressed as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
So, the slope of the new line perpendicular is [tex]\frac{1}{5}[/tex] ;
Now let us find the y-intercept of the new line;
x = -1 and y = 2
2 = [tex]\frac{1}{5}[/tex] x (-1) + c
c = 2 + [tex]\frac{1}{5}[/tex] = [tex]\frac{11}{5}[/tex]
The equation of the new line is;
y = [tex]\frac{1}{5}[/tex]x + [tex]\frac{11}{5}[/tex]
or multiply through by 5;

[tex]\frac{2-1}{3--2} = \frac{1}{5}[/tex]
Answer: 1/5
Step-by-step explanation: Following our hint,
let's start with the slope formula.
m = y₂ - y₁ / x₂ - x₁
We take the second y minus the first y over the second x minus the first x.
So we have m = 2 - 1 / 3 - (-2) or 1 / 5.
So our slope is 1/5.

A factor is a number that divides into another number exactly and without leaving a remainder. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For example, 12 can be factored as 1×12, 2×6, or 3×4.

Since you already have the given slope and the given point, use the Point-Slope Formula to make it a Point-Slope Form:
[tex]y - y_{1} = m(x - x_{1})[/tex]
Slope: [tex]m[/tex]
First Point: [tex](x_{1}, y_{1})[/tex]
-Substitute both the given slope and the given point:
Slope: [tex]-6[/tex]
First Point: [tex](6,4)[/tex]
[tex]\boxed {y - 4 = -6(x - 6)}[/tex] (Substituted in Point-Slope Form)
Answer:
y-4 = -6(x-6)
Step-by-step explanation:
Pre-SolvingGivenWe are given that a line has a slope of -6 and a point of (6, 4).
We want to find the equation of this line in point-slope form.
FormulasPoint-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point.
SolvingSubstitute the value of m (which is -6) into the formula for point-slope form.
[tex]y-y_1=-6(x-x_1)[/tex]

Find the amount to be paid at the end of eight years that is equivalent to a payment of $400 now and a payment of $300 at the end of four years
(a) if 6% simple interest is earned from the date each payment is made and use a comparison date of right now.
(b) if 6% simple interest is earned from the date each payment is made and use a comparison date of eight years from now.
(c) Explain why the fact you get different answers in parts (a) and (b) does not contradict the fact that equations of value at different times are equiv- alent equations.
(d) Repeat parts (a) and (b) except replace "simple interest" with "compound interest."
Answer:
A) $964
B) $651.35
C) The difference in value for part a and part b is due to time factor and the accumulated interest hence it is better to pay $651.35 right now than to pay $964 when you pay $400 now and $300 in four years time
D) $1016.28 , $637.63
Step-by-step explanation:
lets assume the amount to be paid in eight years that is equivalent to payment of $400 now and a payment of $300 at the end of four ( 4 ) years ( FV )
a) since a 6% interest is earned each day of every payment
will use this formula : S = P( 1 + rt )
therefore $400 paid today will a simple interest of = 400 * 0.06 * 8 = $192
$300 paid at the end of four years will earn a simple interest of = 300*0.06*4 = $72
hence FV = $ ( 400 + 192 ) + $ ( 300 + 72 ) = $964
b) when compared with eight years from now
PV = [tex]\frac{FV}{1+rt}[/tex] = ($964) / ( 1 + (0.06*8) = $651.35
C) The difference in value for part a and part b is due to time factor and the accumulated interest hence it is better to pay $651.35 right now than to pay $964 when you pay $400 now and $300 in four years time
D) Repeating parts (a) and (b) using compound interest
using the formula : S = P( 1 + r )^t
therefore $400 paid today will have a compound interest of
= 400 ( 1.06)^8 = $637.54
$300 paid at the end of four years will earn a compound interest of
= 300 ( 1.06 ) ^4 = $378.74
hence FV = 637.54 + 378.74 = $1016.28
when compared with eight years from now
= [tex]\frac{FV}{(1+r)^t}[/tex] = ( 1016.28 ) / ( 1.06 ) ^8 = $637.63

if a scale drawing of a car is 3 inches and the real car is 15 feet what is the scale and scale factor
Step-by-step explanation:
Given parameters:
Scale drawing of the car = 3 inches
Real car = 15feet
Unknown:
Scale = ?
Scale factor = ?
Solution:
The scale is the ratio of the model dimension to the real-life representation.
In this problem, express both quantities in the same unit;
1 foot = 12 inches
15 feet = 15 x 12 = 180inches
Scale;
drawing of the car : Real car
3 inches : 180 inches
Scale 1 inches on drawing is 60inches in real life
Scale factor;
[tex]\frac{real life dimension}{drawing dimension}[/tex] = [tex]\frac{60 inches }{1inches }[/tex] = 60
The scale factor = 60

What is the slope of a line that passes through the points (0, 1) and (2, 6)?
please answer fast as can
Answer:
[tex]\boxed {\boxed {\sf m=\frac{5}{2}}}[/tex]
Step-by-step explanation:
The slope formula is the change in y over the change in x, or:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁,y₁) and (x₂, y₂) are the points the line passes through.
The points given are (0,1) and (2,6). Therefore:
[tex]x_1=0\\y_1=1\\x_2=2\\y_2=6[/tex]
Substitute the values into the formula.
[tex]m=\frac{6-1}{2-0}[/tex]
Solve the numerator.
[tex]m=\frac{5}{2-0}[/tex]
Solve the denominator.
[tex]m=\frac{5}{2}[/tex]
This fraction can not be simplified further, so it is our answer.
The slope of the line is 5/2
Answer:
m=5/2
Step-by-step explanation:
We know that,
[tex]Slope\ (m)=\frac{Rise}{Run}\\Slope\ (m)=\frac{y_2-y_1}{x_2-x_1} \\As here,\\x_1=0, x_2=2\\y_1=1, y_2=6\\Hence,\\Slope(m)\ of\ the\ following\ line\ =\frac{6-1}{2} =2.5[/tex]
