solve the system of equations below by graphing both equations with a pencil and paper what is the solution y=2x-4 y=-x+5
miss Akunina [59]

Answer:

The coordinate of the points on the graph as shown , where                  ( x ,y ) = ( 3 , 2 )

Step-by-step explanation:

Given as :

The two algebraic equation is

y = 2 x - 4   .......A     and  y = - x + 5         ........B

The given two algebraic equation can be solved by putting the one variable to the other equation

Now , put the value of y  from Eq A into the Eq B

I.e 2 x - 4 = - x + 5

or, 2 x + x = 5 + 4

or, 3 x = 9

∴  x = \frac{9}{3}

I.e x = 3

So The value of x = 3

Again,  put the value of x in the equation A

I.e y = 2 x - 4

or, y = 2 × 3 - 4

∴  y = 6 - 4

I.e y = 2

So The value of y = 2

So , The coordinate of points on the graph as ( x , y ) = ( 3 , 2 )

Hence The coordinate of the points on the graph as shown , where               ( x ,y ) = ( 3 , 2 )  Answer

What is the sum of all the angles that are labeled?
Tasya [4]

Based on the information provided, the sum of all the labeled angles is 235° (option b).

<h3>How to calculate the sum of all labeled angles?</h3>

To calculate the sum of all the labeled angles we must add the different values of each labeled angle as shown below:

80° + 92° + 40° + 23° = 235°

According to the above, it can be inferred that the correct option is B because the result of the sum of the values coincides with this sum.

20,I am not sure how to do it
professor190 [17]
Given:
f(x) = x^4 - x

g(x) = x^4 (even)
h(x) = -x (odd)

f(x) as a sum of an even function and an odd function

f(x) = g(x) + h(x)

s(x) = 1 / (x^4 - x)

s(x) as a sum of an even function and an odd function

s(x) = 1 / [g(x) + h(x)]
