y=5-3x\\5x-4y=-3\\\\5x-4(5-3x)=-3\\5x-20+12x=-3\\17x-20=-3\\17x=-3+20\\17x=17\\x=17/17\\x=1\\\\y=5-3x\\y=5-3(1)\\y=5-3\\y=2\\\\5x-4y=-3\\5(1)-4(2)=-3\\5-8=-3\\-3=-3

So:

x=1

y=2

Answer:

The correct options are;

A circular game piece is moved three squares forward

The flag on a mailbox is turned up

Step-by-step explanation:

An isometric transformation also known as isometry, is the rigid motion transformation or movement that preserves the shape, angles, and distances between of a pre-image (object) and the final image.

Rotation, reflection, translation (parallel motion), glide deflection (transformation involving translation and reflection) such as snow footprints are forms of isometric transformation.

polet [3.4K]

Answer:

32cm³

Step-by-step explanation:

the volume of a cone is  

V

=

π

r

in this case, we can relate  

h

and  

r

as we know that the slope =  

h

r

=

we can make the volume a formula in a single variable

V

=

Brainliest to whoever answers this correctly!
Alenkasestr [34]

The slope is a number that tells how steepness it is.

Meaning that the bigger slope it is, the more steepness it is.

We compare how steepness it is. Greater slope, greater steepness.

As plotted the graph of g(x) = -7x - 1

The g(x) does have more steepness than f(x).

Therefore, the answer is A.
