Choice 4, (x,y) (2x,y) I think is the answer, because when you multiply 2 by x, you're expanding the shape
Answer:
Part a) 
Part b) 
Step-by-step explanation:
we have
60 rev/min
Part a) Find the angular speed in radians per minute
we know that
One revolution represent 2π radians (complete circle)
so

To convert rev to rad, multiply by 2π

Part b) Find the linear speed in inches per minute
we know that
The circumference of a circle is equal to

we have
----> given problem
substitute


Remember that
One revolution subtends a length equal to the circumference of the circle
so

To convert rev to in, multiply by 16π

22/25 is the answer and also waffle waffle waffle waffle waffle
<em>Answer:</em>
<em>x=4 y=3</em>
<em>Step-by-step explanation:</em>
<em>rewrite the equations- y=x-1 2x-3y=-1</em>
<em>solve y=x-1 for y</em>
<em>y=x-1</em>
<em>sub for x-1 for y in 2x-3y=-1</em>
<em>2x-3y=-1</em>
<em>2x-3(x-1)=-1</em>
<em>-x+3=-1</em>
<em>-x+3+-3=-1+-3</em>
<em>-x=-4</em>
<em>divide both sides by -4</em>
<em>x=4</em>
<em>sub 4 for x in y=x-1</em>
<em>y=x-1</em>
<em>y=4-1</em>
<em>y=3</em>
<em>WE ARE VENOM</em>
Answer:
×=1
Multiply both sides of the equation by 12, the least common multiple of 4,3.
3x+4(x−1)=3
Use the distributive property to multiply 4 by x−1.
3x+4x−4=3
Combine 3x and 4x to get 7x.
7x−4=3
Add 4 to both sides.
7x=3+4
Add 3 and 4 to get 7.
7x=7
Divide both sides by 7.
x=
7
7
Divide 7 by 7 to get 1.
x=1
