The graph that correctly represents the given system of equations is graph , and the solution to the system is ( ,
what graph would it be, doing this on plato rn.
Answers
The question was incomplete. Below you will find the missing content.
Use the system of equations and graphs below to complete the sentence.
x - 2y = 5
3x + 15y = -6
The graph that correctly represents the given system of equations is a graph ( ), and the solution to the system is ( , ).
The correct option will be Option B: Graph B and the solution of the given system of equations will be (3,-1).
Given the first equation is x-2y=5
in this equation of line, the x-coordinate is:
x-(2.0)=5
⇒ x=5
The x-coordinate will be (5,0).
in this equation of line, the y-coordinate is:
0- 2y=5
⇒y= -5/2
The y-coordinate will be (0,-5/2).
So the first line equation has x-coordinate (5,0) and y-coordinate (0,-5/2).
Similarly,
Given the second equation is 3x+15y=-6
in this equation of line, the x-coordinate is:
3x+(15.0)=-6
⇒ x=6/3=2
The x-coordinate will be (2,0).
in this equation of line, the y-coordinate is:
(3.0)+15y=-6
⇒y= -6/15= -2/5
The y-coordinate will be (0,-2/5).
So the second line equation has x-coordinate (2,0) and y-coordinate (0,-2/5).
Equation-1: x - 2y = 5
⇒x =2y+5
putting the value of x in equation-2
3x + 15y = -6
⇒ 3(2y+5)+15y=-6
⇒6y+15+15y=-6
⇒21y=-6-15=-21
⇒y=-21/21=-1
putting the value of y in equation of x
x= 2(-1)+5= -2+5= 3
The solution of system of equations will be (3,-1)
Checking all the options
In option B one line has x-coordinate (5,0) and y-coordinate (0,-5/2) and another line has x-coordinate (2,0) and y-coordinate (0,-2/5).
And the point of intersection of two lines is (3,-1).
Therefore the correct option will be Option B: Graph B and the solution of the given system of equations will be (3,-1).

Rachel runs 7 miles in 80 minutes. At the same rate, how many miles would she run in 64 minutes?
Answers
Answer:
[tex]\huge\boxed{\sf 5.6 \ miles}[/tex]
Step-by-step explanation:
Given that,
Rachel runs 7 miles in 80 minutes.
80 minutes = 7 miles
Using unitary method
Divide 80 to both sides
1 minute = 7/80 miles
1 minute = 0.0875 miles
Multiply 64 to both sides
64 minutes = 0.0875 × 64 miles
64 minutes = 5.6 miles
So, Rachel will run 5.6 miles in 64 minutes.

Find the holes of the function
Answers
Answer:
(a) none
Step-by-step explanation:
A "hole" in the graph of f(x) is located at an x-value where the left limit of the function and the right limit are the same finite value, but the function is undefined at that value of x.
ExampleThe function f(x) = (x -2)/(x -2) can be reduced to the function f(x) = 1, which is defined everywhere. That reduction occurs when the numerator factor (x-2) cancels the same binomial denominator factor. A graph of the original function will be a straight horizontal line with a "hole" at (2, 1).
The attachment shows a graph.
Given FunctionThe given function can be reduced, but the reduced function remains undefined at x=1/2. Not all of the denominator factors are cancelled there. The function is graphed in the second attachment. At x=1/2, there is a vertical asymptote, not a hole.
[tex]g(x)=\dfrac{(2x-1)(x+4)^2(x-1)(3x+2)}{3x(x-4)(2x-1)^3}\qquad x\notin \left\{0,\dfrac{1}{2},4\right\}\\\\g(x)=\dfrac{(x+4)^2(x-1)(3x+2)}{3x(x-4)(2x-1)^2}\qquad x\notin \left\{0,\dfrac{1}{2},4\right\}[/tex]
There are no holes in the function's graph.
__
Additional comment
A hole can occur for a variety of reasons. In the graph of a rational function, it will generally be found where numerator and denominator zeros cancel each other completely, and the function can be "reduced" to one that is define at the location of those zeros.
It can also occur in piecewise defined functions, where the pieces are defined on adjoining (half) open intervals. For example:
[tex]f(x)=\begin{cases}-x&\text{for }x < 0\\x&\text{for }x > 0\end{cases}[/tex]
has a hole at (0, 0).

The inverse of the function are respectively; f⁻¹(3) = 2 and f⁻¹(8) = 8.5
How to find the inverse of a Function?The formula to find the equation of this function using two coordinates is;
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)
Using the first 2 coordinates, we have;
(y - 1)/(x + 1) = (3 - 1)/(2 + 1)
(y - 1)/(x + 1) = 2/3
3y - 3 = 2x + 2
3y = 2x + 5
y = ¹/₃(2x + 5)
Thus, the inverse is;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(3) = (3*3 - 5)/2
f⁻¹(3) = 2
Similarly;
f⁻¹(x) = (3x - 5)/2

f⁻¹(8) = (3*8 - 5)/2

Answers
The weight of the math and the history book are 72 and 96 ounces respectively.
How to find the weight of a book?A history book weights 24 oz more than a math book.
Therefore,
let
x = weight of math book
weight of history book = 24 + x
The math book is 75% the weight of the history book.
Therefore,
math book weight = 75 / 100 (24 + x)
x = 75 / 100 (24 + x)
x = 1800 + 75x / 100
100x = 1800 + 75x
100x - 75x = 1800
25x = 1800

A company in its first year of business produced 150 training manuals for a total cost of $2.350. The following
year, the company produced 50 more manuals at a cost of $ 1,450. Use this information to find a linear equation
that gives the total cost of producing training manuals from the number of manuals produced.
Answers
Answer:
y = 9x +1000
Step-by-step explanation:
The relation for the total cost of manuals based on the number produced will be the sum of a base cost and a variable cost. The variable cost is the product of the cost per manual and the number of manuals.
Cost per manualThe cost per manual can be found by looking at the increase in cost relative to the increase in the number of manuals produced:
cost per manual = (increase in cost)/(increase in production)
= ($2350 -1450)/(150 -50) = $900/100 = $9
Base costThe base cost will be added to the product of the cost per manual and the number of manuals. For the 2nd year purchase, this is ...
$1450 = base cost + (50 manuals)×($9/manual)
$1450 = base cost + $450
base cost = $1450 -450 = $1000
EquationThe equation for the cost in dollars (y) of producing x manuals can now be described by ...
y = (cost per manual)x +(base cost)
y = 9x +1000
