Answer:
A. {x,y}={-2,-3}
// Solve equation [2] for the variable x
[2] x = 2y + 4
// Plug this in for variable x in equation [1]
[1] (2y+4) - y = 1
[1] y = -3
// Solve equation [1] for the variable y
[1] y = - 3
// By now we know this much :
x = 2y+4
y = -3
// Use the y value to solve for x
x = 2(-3)+4 = -2
B. [1] 3x=3y-6
[2] y=x+2
Equations Simplified or Rearranged :
[1] 3x - 3y = -6
[2] -x + y = 2
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 2
// Plug this in for variable y in equation [1]
[1] 3x - 3•(x +2) = -6
[1] 0 = 0 => Infinitely many solutions
C.Step by Step Solution

System of Linear Equations entered :
[1] 4x - y = 2
[2] 8x - 2y = 4
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 4x - 2
// Plug this in for variable y in equation [2]
[2] 8x - 2•(4x-2) = 4
[2] 0 = 0 => Infinitely many solutions
Answer:
Step-by-step explanation:
a) y = -1/4x --------------(I)
x + 2y = 4 -----------------(II)
Substitute y = (-1/4)x in equation (I)
[tex]x + 2*\dfrac{-1}{4}x=4\\\\\\x -\dfrac{1}{2}x=4\\\\Multiply \ the \ entire \ equation \ by \ 2 \\\\2x -x = 8\\\\x=8[/tex]
[tex]Substitute \ x = 8 \ in \ equation \ (I)\\\\y=\dfrac{-1}{4}*8\\\\\\y = -2[/tex]
Answer: x = 8 ; y = -2
b) y = -x - 2 --------------(i)
3x + 3y = 6 -----------(ii)
Divide equation (ii) by m
x + y = 2
y = -x + 2 ----(iii)
From (i) and (iii), it shows that these lines have same slope. So, they are parallel lines
Answer: No solution
3) -8x + 2y =4
2y = 8x + 4
Divide the entire equation by 2
y = 4x + 2 -------------(i)
y = 4x + 2 ----------------(ii)
From (i) and (ii), we come to know that these lines coincide.So, they have infinite solutions.

12 workers can do a piece of work in 20 days. How many workers should be added to complete the work in 16 days?
(Give answer in process by process)
(Answer is 3 workers)
Given :-
12 workers can do a piece of work in 20 days .To Find :-
How many workers should be added to complete the work in 16 days ?Solution :-
According to the question ,
→ In 20days 12 workers can do a piece of work.
→ In 1day 12*20 workers can do that work
( Less days , more workers )
→ In 16 days 12*20/16 = 15 workers can do the work.
So 15 -12 = 3 workers should be added to complete the work.
Hence the required answer is 3 .

I think the answer is B
To find this out, I used the process of Elimation.
It can't be A, because it is greater than 1.414...
It cant be C, because that's just the number 1
it can't be D, because that's less than 1.414...
So, the answer is B

Is (4,2) a solution to this system of equations?
y = -x + 6
y = 2x - 4
Answer:
No
Step-by-step explanation:
substitute the x- coordinate of the point into both equations and if the value obtained is equal to the y- coordinate then the point is a solution.
y = - 4 + 6 = 2 ← true
y = 2(4) - 4 = 8 - 4 = 4 ≠ 2 ← false
Thus the point is not a solution to the system

The lateral surface area of a cylinder can be defined as the surface area of all of the sides of the cylinder excluding its base and top is calculated using lateral_surface_area = 2* pi * Radius * Height. To calculate Lateral Surface Area of a Cylinder, you need Radius (r) & Height (h).
but instead, will be using 3.14
2*3.14*4.9*11.2

Step-by-step explanation:
What is the domain of the function y = StartRoot x 6 EndRoot minus 7?.
A function is a mapping from domain to range. The domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)
What is domain and range of a function?Domain is the set of values for which the given function is defined.Range is the set of all values which the given function can output.One method of finding the domain of a function is to start by finding the values for which it isn't defined.
Assuming that the function [tex]y = \sqrt{x+6} - 7[/tex] is defined for only real numbers, then, as we know that:
[tex]\sqrt{x}[/tex] exists only if x is non-negative, which means for [tex]\sqrt{x+6}[/tex] to be defined, we need
[tex]x + 6 \geq 0\\x \geq -6[/tex]
No other way is there for the function to be non-existing.
Thus, the values on which the function is defined is all real numbers bigger or equal to -6. This is the domain of the given function.
Thus, the domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

Which statement about f(x) and its translation, g(x), is true? The domain of g(x) is {x | x > 6}, and the domain of f(x) is {x | x > 0}. The domain of g(x) is {y | y > 0}, and the domain of f(x) is {y | y > 6}. The asymptote of g(x) is the asymptote of f(x) shifted six units down. The asymptote of g(x) is the asymptote of f(x) shifted six units up.
The correct statement about f(x) is the asymptote of g(x) is the asymptote of f(x) shifted six units up.
The given functions are;
F(x) = 7x
g(x) = 7x + 6
Parent functionA parent function is the simplest function that still satisfies the definition of a certain type of function.
We can see that 6 has been added to the function f(x) to get the function g(x).
We know that when we add some constant 'c' in the function then the function gets shifted upward by 'c' units.
Therefore, we will get g(x), when we will shift f(x) upward by 6 units.
Both functions are linear functions hence, the asymptote of g(x) is the asymptote of f(x) shifted six units up.
Hence, the correct statement about f(x) is the asymptote of g(x) is the asymptote of f(x) shifted six units up.

Tiana is 25 years old. She lives with a roommate and a dog. She has worked at a fancy restaurant for 6 months. She works 40 hours per week and makes $2.13 per hour. She usually serves 45 tables per week. The average bill at the restaurant is $130 per table, and she typically receives a 20% tip. How much does she make in a typical week?
Answer:
$1,255.5 dollars per week
Step-by-step explanation:
40Hr * $2.13 = $85.2 per week from hours alone
$130 * 0.20 = $26 tip per table
$26 * 45 tables = $1,170 in tips
$85.2 + $1,170 = $1,255.2 per typical week
A toy shop has stuffed Ana I’m als originally priced at $25 each. There is now a 20% discount on the stuffed animals. What is the sale price of each stuffed animal?
Answer:
$20 for each stuffed animal
Step-by-step explanation:
[] The original price is $25, but it is 20% off.
100% - 20% = 80%
[] Now we can find 80% of $25.
-> First, 80% divided by 100 becomes 0.8, a decimal we can work with
25 * 0.8 = 20

Signs of trig functions:
Answer:
Step-by-step explanation:
Each one of the trig functions is plus in two quadrants.
The sin(theta) is plus in 2
The Tan(theta) is plus in 3
The cos(theta) is plus in 4
Rule: if the trig function is not plus, then it is minus.
So if Tan (theta) is minus it means theta is in quad 2 or quad 4
So in this case theta is either in quad 2 or quad 4.
The sin is plus, that means that theta is in quad 2.

an employee earns $31.20 after four hours and $54.60 after seven hours. What is the employees hourly rate of pay?
Answer:
$7.80 an hour
Step-by-step explanation:
$31.20/4 = 7.8
$54.60/7 = 7.8
Answer:
$7.80 per hour
Step-by-step explanation:
I know this equation might seem a bit complicated, but it's actually really simple. Just divide.
$31.20/4 = $7.80
Now we just have to make sure the second one matches.
$54.60/7 = $7.80
Since they both match, the hourly rate of pay is $7.80.
