Solve the system of equations -5y-10x=45. -3y+10x=-5 x= y=
yKpoI14uk [10]

Answer:

x  = -2

y = - 5

Step-by-step explanation:

-5y - 10x = 45

-3y + 10x = -5

------------------------Add

-8y = 40

  y = -5

-3(-5) + 10x = -5

15 + 10x = -5

10x = -20

  x = -2

Answer

x  = -2 and y = - 5

How can you tell there is no solution of a system of equations by looking at the equations or the graph? Explain.​
sashaice [31]
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.

A projectile is fired into the air with an initial vertical velocity of 160 ft/sec from ground level. How many seconds later doe
djverab [1.8K]

The maximum height of the projectile is the maximum point that can be gotten from the projectile equation

The projectile reaches the maximum height after 5 seconds

The function is given as:

\mathbf{h(t) = -16t^2 + 160t}

Differentiate the function with respect to t

\mathbf{h'(t) = -32t + 160}

Set to 0

\mathbf{h'(t) = -32t + 160 = 0}

So, we have:

\mathbf{-32t + 160 = 0}

Collect like terms

\mathbf{-32t =- 160 + 0}

\mathbf{-32t =- 160}

Solve for t

\mathbf{t = \frac{- 160}{-32}}

\mathbf{t = 5}

Hence, the projectile reaches the maximum after 5 seconds
