Answer:

(2,4) is a solution to this system of equations

Step-by-step explanation:

Given system of equation are

$y=2x \hfill (1)$

$y=\frac{-1}{2}x+5\hfill (2)$

To find the solution of the given system of equations

To Check that (2,4) is a solution to this system or not

Solving equations (1) and (2)

From equation (1) and y=2x

Now substitute y=2x is equation (2)

$2x=\frac{-1}{2}x+5$

$\frac{-1}{5}x+5-2x=0$

$5-\frac{x}{2}-2x=0$

$5-\frac{x+4x}{2}=0$

$5-\frac{5x}{2}=0$

$\frac{10-5x}{2}=0$

10-5x=0

-5x=-10

$x=\frac{10}{5}$

Substitute x=2 in equation (1)

y=2x

y=2(2)

Therefore y=4

Therefore the solution is (2,4)

Therefore (2,4) is a solution to the system of equations.

A home is to be built on a 56 foot 9 inch wide lot. The house is 5 feet 5 inches from the side of the lot and is 34 feet 10 inch

daser333 [38]

Total lot - house -other side
=(56 ft 9 in) - (34 ft 10 in) - (5 ft 5 in)
=(55 ft 21 in) - (34 ft 10 in) - (5 ft 5 in)
=16 ft 6 in
Convert to inches: 16 ft x 12 in/ft)+ 6 in= Total in inches192 in + 6 in= Total in inches
198 in= Total in inches
Check: One side + house + other side = Lot width
(5 ft 5 in)+(34 ft 10 in)+(16 ft 6 in)=Lot width
56 ft 9 in=Lot width, which equals the given.
