Solving systems of equations using substitution

Mathematics

You are told that y=-5, so just use that value for y in the second equation...

5x+4(-5)=-20

5x-20=-20

5x=0

x=0 so the solution, when the lines intersect, is the point (0,-5)

Answer:

v = 25.98

Step-by-step explanation:

You could do this a number of ways. Some are much longer than others. The shortest way is to use the tangent.

Formula

Tan(theta) = opposite / adjacent

Givens

Theta = 30o

Opposite = 15 km

Adjacent = x

Solution

tan(30) = 15 / v                       Multiply both sides by v

v*tan(30) = 15                         Divide by tan(30)

v = 15/tan(30)

tan(30) = 0.5774

v = 15 / 0.5774

v = 25.98
