Answer:

Graphic Representation of the Equations is in the image above

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = 4x - 5

// Plug this in for variable y in equation [1]

[1] (4x-5) - 2x = -1

[1] 2x = 4

// Solve equation [1] for the variable x

[1] 2x = 4

[1] x = 2

// By now we know this much :

y = 4x-5

x = 2

// Use the x value to solve for y

y = 4(2)-5 = 3

Solution :

{y,x} = {3,2}

Answer:

Part 1:

You can solve the pair of equation graphically by writing the y-intercepts which are (0,-1) and (0,-5) Then follow the slopes of each line till the intercept. The slopes are up 2 over 1 and up 4 over 1 respectivily

Part 2:

When you graph these you get the answer of (2,3)

x is 2 and y is 3

Step-by-step explanation:

Hope it helps :)

X^2 - 10x - 20 = 0, which number would have to be added to "complete the square"?
Airida [17]

Answer:

45

Step-by-step explanation:

When you're completing the square you're adding (b/2)^2 which in this case is (-5)^2 or 25. This is because when you rewrite it as a square binomial you write it in the form (x+(b/2))^2 which is going to result in x^2+b+(b/2)^2. Since you need to reach 25 you need to add 45 since the last value is at -20.

A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.

If b is any number such that and then an exponential function is a function in the form, where b is called the base and x can be any real number.
