Solve using substitution x=(3y+1) and x+4y=15
natka813 [3]

The solution is: x= 7 and y = 2

Step-by-step explanation:

Given equations are:

x = 3y+1\ \ \ \ Eqn\ 1\\x+4y = 15\ \ \ \ Eqn\ 2

Putting x = 3y+1 in equation 2 from equation 1

3y+1+4y = 15\\7y+1 = 15\\

Subtracting 1 from both sides

7y+1-1 = 15-1\\7y = 14

Dividing both sides by 7

\frac{7y}{7} =\frac{14}{7}\\y = 2

Putting y=2 in equation 1

x = 3(2) +1\\x = 6+1\\x = 7

Hence,

The solution is: x= 7 and y = 2

I need answer for this quick please
Anna007 [38]

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = \frac{-36-(-6)}{4-(-1)} = \frac{-36+6}{4+1} = \frac{-30}{5} = - 6
