Answer:

x=3, y= -2

Step-by-step explanation:

Multiplying :

(4x+3y =6)*-3

(3x+5y =-1)*4

-12x -9y= -18

12x+20y= -4

Add the equations

20y-9y = -4-18

11y = -22

y= -22/11 = -2

3x +5* -2= -1

3x -10 = -1

3x = 10-1

x= 9/3 =3

Det Eminem’s the volume of a sphere with a radius of 0.48 inch round your answer to the nearest hundredth
levacccp [35]
0.50 because the 8 is in the hundredth place and is greater than 5 so you round it up. Then you turn that to a zero because the 8 becomes a 10 but you only use the zero. Then you turn the 4 to a 5 or else the number would be getting smaller and not larger.

Given: f(x) = 2x-1 and g(x) = 2x-3<br> Find:<br> (fog)(x)<br> HELP PLEASEE!!
Murljashka [212]

Answer:

(fog)(x) = 4x - 7

Step-by-step explanation:

f(x) = 2x-1 and g(x) = 2x-3;

(fog)(x) = f(g(x)

= f(2x - 3) = 2(2x - 3) - 1

= 4x - 6 - 1

= 4x - 7
