Answer:

Step-by-step explanation:

m(t)=t³-12t²-144t

Take the derivative of t:

t'=3t²-24t-144

Set it to 0:

3t²-24t-144=0

Solve for t:

t²-8t-48=0

(t-12)(t+4)=0

t=12 or -4

On a graph, you'll find that the maximum value occurs at t=-4 ..............

Follow these steps:

-8.4b - 4.2 = 12.6

Add 4.2 on both sides:

-8.4b = 16.8

Divide by -8.4 on both sides to give you the final answer of:

b = -2

So you're answer is indeed correct! Hope this helps and that the steps are clear enough!

Y’all give me dis answer to

Leto [7]

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4 Eqn 1

4x+y = 1 Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

$4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3$

Putting y = -3 in equation 1

$x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1$

Hence,

The solution is: (1,-3)
