Substitute -x-5 for y
Gets you:
3x-2(-x-5)
Distribute the 2
3x-(-2x-10)
Distribute the -1
3x+2x+10
Combine like terms
5x+10
Subtract 10 from both sides
5x=-10
Divide by 5
x = -2

Does the point (273, 2) lie on the circle that is centered at the origin and contains the point (0, -4)? Explain?

valina [46]

Answer:

No, the point (273, 2) does not lie on the circle that is centered at the origin and contains the point (0, -4)

Step-by-step explanation:

The circle centered at the origin that contains the point (0,-4) has equation:

${x}^{2} + {y}^{2} = 16$

If the point (273,2) lies on this circle , then it must satisfy this equation:

${273}^{2} + {2}^{2} = 74533$

Since

$16 \ne74533$

The point does not lie on this circle.

A loaded grocery cart is rolling across a parking lot in a strong wind. You apply a constant force F⃗ =( 35 N )i^−( 37 N )j^ to

Trava [24]

Answer:

-189.8 J

Step-by-step explanation:

We are given that f

Force applied=F=35 Ni-37 Nj

Displacement, s=(-8.7m)i-(3.1m)j

We have to find the work done .

We know that

Work done= $F\cdot s$

Using the formula

Work done= $(35i-37j)\cdot (-8.7-3.1)$

Work done= $-304.5+114.7$

Using $i\cdot i=j\cdot j=k\cdot k=1,i\cdot j=j\cdot i=j\cdot k=k\cdot j=i\cdot k=k\cdot i=0$

Work done=-189.8J

Hence, the work done =-189.8 J
