Answer:

I keep getting no solution

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−4)=−9+5x+15

(5)(x)+(5)(−4)=−9+5x+15(Distribute)

5x+−20=−9+5x+15

5x−20=(5x)+(−9+15)(Combine Like Terms)

5x−20=5x+6

Step 2: Subtract 5x from both sides.

5x−20−5x=5x+6−5x

−20=6

Step 3: Add 20 to both sides.

−20+20=6+20

0=26

What are the powers of 3 through 1000? AND DONT JUST SAY A FEW I NEED ALL OF THEM

galben [10]

Answer:

1, 3, 9, 27, 81, 243, 729

Step-by-step explanation:

The powers of 3 are:

$3^0 = 1$

$3^1 = 3$

$3^2 = 9$

$3^3 = 27$

$3^4 = 81$

$3^5 = 243$

$3^6 = 729$

$3^7 = 2187$

And so on...

So through 1000: 1, 3, 9, 27, 81, 243, 729

A merry go round revolves 2 times per minute, jack is 10 feet from the center while bob is 14 feet from the center

Nesterboy [21]

Answer:

Jack's linear speed is 126ft/min

Bob's linear speed is 176ft/min

Step-by-step explanation:

First of all, find the circumference of both circles given the radius; Jack, 2<em>pi</em>r (10)=63ft. Bob 2<em>pi</em>r(14)=88ft. Now, realize that the merry go round revolves 2 times per min; 2rpm, so multiply each result by 2 and there you go.

Answer:

The vertex that maximize the problem is (2,000,4,000)

Step-by-step explanation:

we have

$z=10x+6y$

The vertex of the shaded region are

A(0,0), B(4,000,0),C(2,000,4,000), D(0,6,000)

Substitute the value of x and the value of y of each vertex in the z equation to find the solution

case A) A(0,0)

$z=10(0)+6(0)=0$

case B) B(4,000,0)

$z=10(4,000)+6(0)=40,000$

case C) C(2,000,4,000)

$z=10(2,000)+6(4,000)=44,000$

case D) D(0,6,000)

$z=10(0)+6(6,000)=36,000$

therefore

The vertex that maximize the problem is (2,000,4,000)
