00 Which graph shows the solution to the system of equations? x+y=4 x - y = -2

Mathematics
1 answer:
zheka24 [161]4 years ago
8 0

Answer:

The solution is (1, 3).

Step-by-step explanation:

Solving the second equation for x, we get x = y - 2.

Substituting y - 2 for x in the first equation, we obtain y - 2 + y = 4, or

2y = 6

Then y = 3.  

Substituting 3 for y in the 1st equation, we get x + 3 = 4, or x = 1.

The solution is (1, 3).

Fill in the missing numbers to complete the linear equation that gives the rule for this table.
irakobra [83]

The value of the missing number to complete the linear equation are 31 and -10 respectively.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here the given tables shows the coordinates of the linear equation and to find the equation  we consider any two points let suppose the those two points be (0,-10) and (1,21).

Now using slope formula to find the slope of line m :

m = (y₂-y₁)/ (x₂-x₁)

m = (21-(-10))/(1-0)

m = 31

Let us first find the equation of the line using point-slope equation of line :

(y-y₁) = m(x-x₁)

Substituting all the values in above equation to get the equation of line :

(y-(-10)) = 31(x-0)

(y+10) = 31x

y = 31x - 10

Therefore, the value of the missing number to complete the linear equation are 31 and -10 respectively.

What does x equal? 3(x-7)=138+3x
Arturiano [62]
3(x-7) = 138 + 3x      First multiply
3x-21 = 138 + 3x      subtract 3x from both sides 
-21 = 138            

This is a false statement because -21 does not equal to 138 so the answer is no solution.
