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

Use the distributive property to simplify the expression.
zepelin [54]

Option D

Using the distributive property, -7(8x – 3) + x = -55x + 21

<em><u>Solution:</u></em>

Given that we have to use distributive property to simplify the given expression

Given expression is:

-7(8x – 3) + x

Let us first understand about distributive property

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

<em><u>The distributive property is represented as:</u></em>

a(b + c) = ab + ac

Apply this property in given expression for -7(8x - 3)

-7(8x - 3) = (- 7 \times 8x) + (-7 \times -3)\\\\-7(8x - 3) = -56x +21

Apply the above result in given expression

-7(8x - 3) + x = -56x + 21 + x

Combine the like terms. Add -56x and x

-7(8x - 3) + x = -56x + 21 + x = -55x + 21\\\\-7(8x - 3) + x = -55x + 21

Thus the given expression is simplified. Option D is correct

a local hamburger shop sold a combined total of 456 hamburgers and cheeseburgers. The number of cheeseburgers sold was three tim
Ganezh [65]
H + c = 456
c = 3h

h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold

c = 3h
c = 3(114)
c = 342......cheeseburgers sold
