x + 2y = 2

-1x + 1y = 5 Is not the correct answer!!!

The options are

a) 2x + 4y = 4

-3x +y = -1

b) 2x + 4y = 4

7x + 5y = -1

c) 2x + 4y = 4

7x - y = 5

d) 2x + 4y = 4

Answer:

x+2y=2

-1x+1y=5

Step-by-step explanation:

Any system whose equations have the following characteristic

x+2y=2

-1x+1y=1

Is equivalent to the original system, since the differ in a number, the first equation is divided by 2 and the second by 5, we can say any system is equivalent to the original when it is escalated  by a factor between its functions.

a rectangular prism is 18 inches long 6 1/2 inches wide and has a volume of 292 1/2 cubic inches. which equation can u use to fi
zhuklara [117]

The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches

<h3>Volume of a rectangular prism</h3>
  • v = lwh

where

l = length

w = width

h = height

Therefore,

l = 18 inches

w = 6 1 / 2  = 13 / 2 inches

h  =?

v = 292 1 / 2  = 585 / 2

Therefore,

h = v / lw

h = 585 / 2 × 1 / 18 × 2 / 13

h = 585 / 234

h = 2.5 inches

Complete the table of values for..
nexus9112 [7]

Answer:

Step-by-step explanation:

y = x² + x - 3

x = - 3

y = ( - 3 )² + ( - 3 ) - 3 = 3

( - 3 , <em>3</em> )

x = 0 ⇒ y = - 3

( 0 , <em>- 3</em> )

x = 1

y = ( 1 )² + ( 1 ) - 3 = - 1  

( 1 , <em>- 1 </em>)

<em>(b).</em> Coordinate x of the vertex of quadratic equation y = ax² + bx + c is

- \frac{b}{2a}

x = - \frac{1}{2(1)} = - \frac{1}{2} = - 0.5

y = ( - 0.5 )² + ( - 0.5 ) - 3 = - 3.25 = - 3\frac{1}{4}

( - \frac{1}{2} , - 3\frac{1}{4} )
