-2x-9y=-25 -4x-9y=-23

1 answer:

8 0

So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you −2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on

but at the end you should get x=-1 and y =3

Given the function f(x)=3x-5, for which value in the domain does f(x)=-38?

victus00 [196]

$f(x) = -38\\\\\implies 3x -5 = -38\\\\\implies 3x = -38 +5 \\\\\implies 3x = -33\\\\\implies x = -\dfrac{33}{3}\\\\\implies x = -11$

The width of the enlarged photo is 9 inches.

Given:
Original length = 2 inches
Original width = 1 inch
Extended length = 18 inches
Extended width = ?

2:1 = 18:x
2x = 1*18
2x = 18
2x/2 = 18/2
x = 9 * extended width.

to check:
2:1 = 18:9
2*9 = 1*18
18 = 18
