we have

y=-\frac{5}{2}x-7 ------> equation A

x+2y=4 ------> equation B

we know that

The intersection point both graphs is the solution of the system of linear equations

Using a graphing tool

see the attached figure

The solution is the point (-4.5,4.25)

therefore

the answer is the option A

(-4.5,4.25)

AveGali [126]
No, the trailer cannot hold the weight of the bricks. It is beyond the 900kg capacity of the trailer. The total weight of the bricks is 1,013.77 kilograms. The total weight was derived from getting the volume of the brick (0.051m x 0.102m x 0.203m), then multiplying the volume to the density of each brick (1.056 x 10^3m^3 x 1920kg/m^3). The weight of each brick is 2.03kg. Lastly, multiply the total number of bricks to the weight of each brick to get the total weight.
