Answer:
x = 3.405; y = 5.238

Steps:
1.) cancel out the x’s
2(5x+2y=27.50) -5(2x+5y=33.00)
10x+4y=55 -10x-25y=-165

2.) solve the equation and subtract them
10x+4y=55
-10x-25y=-165
———————
-21y=-110

3.) divide -21 by -110 to isolate the y
-21/-110=5.238 (about)
y=5.238

4.) plug y back into one of the equations
2x+5(5.238)=33.00

5.) solve for x
2x+26.19=33.00
-26.19 -26.19
—————————
2x=6.81

6.) divide 2 by 6.81
2/6.81=3.405
x=3.405

Quadrilateral TRAM is rotated -90 degrees about the origin. Draw the image of this rotation.
SpyIntel [72]

Answer:

Please find attached the image of the quadrilateral TRAM after a rotation of -90 degrees, created with MS Excel

Step-by-step explanation:

The given coordinates of the vertices of the quadrilateral TRAM are;

T(-5, 1), R(-7, 7), A(-1, 7), M(-5, 4)

By a rotation of -90 degrees = Rotation of 90 degrees clockwise, we get;

The coordinates of the preimage before rotation = (x, y)

The coordinates of the image after rotation = (y, -x)

Therefore, we get for the the quadrilateral T'R'A'M', by rotating TRAM -90 degrees as follows;

T(-5, 1) → T'(1, 5)

R(-7, 7) → R'(7, 7)

A(-1, 7) → A'(7, 1)

M(-5, 4) → M'(4, 5)

The image of TRAM after -90 degrees rotation is created by plotting the derived points of the quadrilateral T'R'A'M' on MS Excel and joining the corresponding points as presented in the attached diagram.

It is 240 miles from Boston to New York.
Volgvan

It takes you 4.8 hours to reach New York

Step-by-step explanation:

The given is:

  • It is 240 miles from Boston to New York
  • You drive at a speed of 50 mph

We need to find how long would it take you to reach New York

Distance (d) = speed (v) × time (t)

∵ The distance between Boston and New York is 240 miles

∴ d = 240

∵ You drive at a speed 50 miles per hour

∴ v = 50

- Substitute these values in the rule of the distance above

∴ 240 = 50 × t

- Divide both sides by 50

∴ 4.8 = t

∴ The lime of the trip is 4.8 hours

It takes you 4.8 hours to reach New York
