Solve the following systems by substitution
Paladinen [302]

Answer:

The answer to your question is below

Step-by-step explanation:

Question 1

                x = 5                       Equation l

                2x + y = 10              Equation ll

- Substitute Equation l in equation ll

               2(5) + y = 10

                y = 10 - 10

                y = 0

- Solution  (5, 0)

Question 2

                 x + 16y = 20          Equation l

                 x = 4y                    Equation ll

Substitute equation ll in equation l

                4y + 16y = 20

                        20y = 20

                           y = 20/20

                           y = 1

-Find x

                x = 4(1)

                x = 4

-Solution

                (4, 1)

Question 3

                   2x + 8y = 20            Equation l

                     x = 2                       Equation ll

-Substitute equation ll in equation l

                   2(2) + 8y = 20

                      4 + 8y = 20

                            8y = 20 - 4

                            8y = 16

                              y = 16/8

                              y = 2

- Solution

                   (2, 2)

Kevin claims he can draw a trapezoid with three right angles. Is this possible? Explain.
statuscvo [17]
No it is NOT possible - that would mean the final angle would also have to be ninety degrees making it a square or rectangle. :)

A rocket is launched from the ground and travels in a straight path. The angle of inclination of the rocket's path is 1.2 radian
gladu [14]

Answer:

a)S=2.57

b)H=203.2yard

c)X=121.79yards

Step-by-step explanation:

From the question we are told that:

Angle \theta=1.2=68.755^o

a)

Generally the equation for Slope is mathematically given by

 S=tan \theta

 S=tan 68.755

 S=2.57

b)

Given the right Angle triangle with horizontal distance x=85yard

Generally the equation for Height traveled is mathematically given by

 H=tan\theta*x

 H=2.57*85

 H=218.45

 H=203.2yard

c)

Generally the equation for Horizontal Distance traveled at 313 height traveled is mathematically given by

X=\frac{313}{tan65.75}

X=\frac{313}{2.57}

X=121.79yards
