Answer:

A: 5

28-3x=13 You have to get rid of 28, so you

-28 -28 subtract 28 from both sides. 28-28 and 13-28

-3x=-15 Now you have to divide both sides by -3

<u>-3x</u> = <u>-</u><u>1</u><u>5</u> So, on the left side, you get 1 or just x, -3 -3 and on the right side 5

x=5

I really hope that makes sense

The system of equations y= 1/4 x-1and y=-1/2 x-1/4 shown on the graph below
Ksenya-84 [330]

Answer:

The value of x , y coordinate is ( 1, \dfrac{-3}{4} )

and Plotting the points on graph

Step-by-step explanation:

Given as :

The system of equation is

y = \dfrac{1}{4} x - 1

The equation can be written as

4 y = x - 4

Or, 4 y - x + 4 = 0                         ........1

y = - \dfrac{1}{2} x - \dfrac{1}{4}

The equation can be written as

4 y + 2 x + 1 = 0                            ..........2

Solving the equation

i.e ( x - 4 ) + 2 x + 1 = 0

or, 3 x - 4 + 1 = 0

or, 3 x = - 1 + 4

∴ 3 x = 3

I.e x = 1

Put the value of x in eq 1

So, 4 y - x + 4 = 0        

or, 4 y - 1 + 4 = 0      

or, 4 y + 3 = 0

or, 4 y = - 3

 ∴ y = \dfrac{-3}{4}

So, The value of x , y coordinate is ( x ,y ) =  ( 1 ,  \dfrac{-3}{4} )

Hence The value of x , y coordinate is ( 1, \dfrac{-3}{4} )

and Plotting the points on graph  Answer

What is the product of -8/1 * -1/8​
spayn [35]

Answer:

1

Step-by-step explanation:

To multiply fractions, you multiply the numerator by the numerator and the denominator by the denominator. -8*-1 will turn positive because there are 2 negative signs, and will become 8. 1*8 is 8.

The fraction is now 8/8, which can be simplified to 1.

Therefore, 1 is the correct answer.
