The solution to the equation 7k - 14 = 42 is k = 8
Given data:
The expression is represented as 7k - 14 = 42.
To solve the equation 7k - 14 = 42, isolate the variable k by performing the necessary steps in a commanding tone.
Step 1: Add 14 to both sides of the equation to eliminate the -14 term on the left side:
7k - 14 + 14 = 42 + 14
On simplifying:
7k = 56
Step 2: Divide both sides of the equation by 7 to solve for k:
7k/7 = 56/7
k = 8
Hence, the solution to the equation k = 8.

Domain = All real numbers
Range = y ≥ 0
Step-by-step explanation:
As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers
Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it can still be 0) Since y can only be positive... we define the Range as y ≥ 0

2x^{3}+30xx^{2} +72x=0 solve using zero product property
Answer:
Values of x are: x=0 or x=-3 or x=-12
Step-by-step explanation:
The equation given to solve using zero product property is [tex]2x^3+30x^2+72x=0[/tex]
Zero property rule states that if ab=0 then a=0 or b=0
Taking x common from the equation:
[tex]2x^3+30x^2+72x=0\\x(2x^2+30x+72)=0\\[/tex]
Applying zero product rule
[tex]x(2x^2+30x+72)=0\\x=0 \ or \ 2x^2+30x+72=0[/tex]
Now, solving [tex]2x^2+30x+72=0[/tex]
Using quadratic formula to find value of x
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
Putting values
[tex]$x=\frac{-30\pm\sqrt{(30)^2-4(2)(72)}}{2(2)}$\\$x=\frac{-30\pm\sqrt{324}}{4}$\\$x=\frac{-30\pm18}{4}$\\$x=\frac{-30+18}{4} \ or \ x=\frac{-30-18}{4}$ \\x=-3 \ or \ x=-12[/tex]
So, Values of x are: x=0 or x=-3 or x=-12

Anybody know how to do algebra?
Answer:
The solution of a system of equations is the point(s) that lies on both lines. Therefore if the 2 lines cross over each other then there is exactly one solution. If they have no solution it means they are parallel since they don't share a single point and if they are overlapping lines then there is an infinite amount of solutions since they share the same points.
In this case it must have 1 solution.
To find which point is correct you should be able to plug in the same point for the x and y of the equations so that they are valid.
For example in the equation y=2x and y=-1/2x we need to find the point in which will work for both equations. In this case 0,0 is correct (0=0, 0=0)
So lets plug in the points and find the correct solution:
A. -1=-2+5
-1=-3 - this isn't true since -1 cant possibly equal -3. Therefore this point is incorrect.
B. 3=-2+5
3=3 - this is valid
______________
3=-2(-2)-1
3=4-1
3=3 - this is also valid
Therefore B is correct

The slope of a line is - 1/5, and the y-intercept is 5. What is the equation of the line written in general form?
O x - 5y - 5 = 0
Ox - 5y - 25 = 0
Ox+ 5y - 25 = 0
Answer:
x+5y-25
Step-by-step explanation:
Slope Intercept form equation: -1/5x+5=y
Convert to General:
1. 1/5x+y=5 (move variable terms to one side)
2. x+5y=25 (multiply by five to remove fractions)
3. x+5y-25=0 (move 25 over to set equal to zero)
