The graph represents this system of equations y equals 4 - x y equals x - 2 what is the solution to the system of equations

babunello [35]

The solution to the system of equations is (3,1)

Step-by-step explanation:

The system of equations represented by graph are:

$y=4-x\\y=x-2$

Solving the system of equations

Let:

$y=4-x\,\,\,eq(1)\\y=x-2\,\,\,eq(2)$

Putting value of y from eq(2) into eq(1):

$x-2=4-x\\Simplifying:\\x+x=4+2\\2x=6\\x=6/2\\x=3$

So, Value of x = 3

Putting value of x into eq(2)

$y=x-2\\y=3-2\\y=1$

So, value of y= 1

So, The solution to the system of equations is (3,1)

Read the proof. Given: m∠H = 30°, m∠J = 50°, m∠P = 50°, m∠N = 100° Prove: △HKJ ~ △LNP Triangles H K J and L N P are shown. Trian

SVETLANKA909090 [29]

Answer:

Triangle Sum Theorem

Step-by-step explanation:

Statement

2. m∠H + m∠J + m∠K = 180°

Reason

Triangle Sum Theorem

Comments

-----------

In any given triangle the sum of its interior angles must be equal to 180º.

This has to do with lines and parallelism, and if you trace a Triangle and to parallel lines one of them being the base of it, this can be proven too.

The house is 7 years old right now.

<h3>What are word problems in algebraic equations?</h3>

Word problems leading to algebraic equations are real-life problems that can be interpreted and solved with the use of variables and arithmetic operations.

From the information given:

Let us assume that the age of the house is (m)

Now, the amount paid on the mortgage is:

m + 21

This is equal to 4 times as old as it is now;

i.e.

m + 21 = 4m

m- 4m = -21

-3m = -21

m = -21/-3

m = 7

Therefore, we can conclude that the house is 7 years old.

The cost of 9 scarves is $69.75. What is the unit price?

NISA [10]

The "Unit Price" (or "unit cost") tells you the cost per liter, per kilogram, per pound, etc, of what you want to buy.

Just divide the cost by the quantity: 69.75/9=$7.75

Hope this helps, have a BLESSED and wonderful day! As well as as a safe one! :-)
