The solution of 2x2 + x = 3 is shown below.
2x2 + x – 3 = 0
(2x + 3)(x – 1) = 0
x = –1.5 or x = 1
Based on this work, the solution of the system of equations is
A. {(-1.5, -6.5), (1, 7)}
B. {(-1.5, 9.5(, (1, 7)}
C. {(-1.5, 9.5), (1, 9)}

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
