Look at the system of equations: 2x + 6y = 10
5x + 15y =25
(HINT: solve for y=mx+b to graph!)

Which of these statements is correct?
A. The system has no solution
B. The system has an infinite number of solutions
C. The system has one solution at (-1,2)
D. The system has one solution at (5,0)

B

Step-by-step explanation:

Both C and D solve the equations, so the system must have infinite solutions.

i do not know this sorry : (

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
