Answer:the number of gallons of water left in the tub after it has drained for x minutes is 300 - 8x

Step-by-step explanation:

A hot tub that holds 300 gallons of water drains at a rate of 8 gallons.

Let x represent the number of minutes for which the hot tub has drained water.

If the hot tub drains 8 gallons of water per minute, it means that in x minutes, the number of gallons of water that the hot tub would have drained is 8x

Therefore, the number of gallons of water left in the tub after it has drained for x minutes would be

300 - 8x

Consistent means 1 solution
inconsistent means no solutions....because they are parallel lines
equivalent means infinite solutions...because they are the same line

y = 3x - 2             3x - y = 4
                            -y = -3x + 4
                             y = 3x - 4

both equations have the same slope but different y intercepts....this means they are parallel lines and have no solutions ....INCONSISTENT
=======================
1/2y = -x + 5                  2y = -4x + 20   
y = -2x + 10                     y = -2x + 10

same equation.....same line...infinite solutions...EQUIVALENT
===================
y = -x + 4               x = -y - 6
                              y = -x - 6

same slope, different y intercepts....parallel lines......no solutions...this means INCONSISTENT
==================
y = 4x + 2                y = 6x - 10
different slopes, different y intercepts...one solution...CONSISTENT
==================
y = 2x + 1               y = -2x + 3
different slopes, different y intercepts...one solution...CONSISTENT
=================
-2x + 5y = 0              y = 2/5x
5y = 2x
y = 2/5x
same line....infinite solutions....EQUIVALENT

Given triangle JKL,write the coordinates of the vertices of a triangle J’K’L’ that result from a translation of triangle JKL two
sweet [91]

Step-by-step explanation:

since I don't have any data about the coordinates, I am simply calling them xj, yj, and xj' and yj'.

J = (xj, yj)

K = (xk, yk)

L = = (xl, yl)

a translation (shift) 2 units to the left just means, that the y coordinates regain the same, but the x coordinates are decreased ("to the left" = getting smaller) by 2.

J' = (xj - 2, yj)

K' = (xk - 2, yk)

L' = (xl - 2, yl)

a tour bus cost $75 plus $6 for each passenger. write and evaluate an expression to find the total cost for 25 passengers. then.
miskamm [114]
To make an expression for any amount of passengers, you need to use x for each passenger. Fill in x with the amount of passengers. Your equation is: 
75 + 6x. Now using this expression, we can find the answer to all of the amounts of passengers.

75 + 6(25) = 225; 75 + 6(26) = 231; and so on. Hope that I helped! Good luck!

What are the solutions to the equation 3(x – 4)(x + 5) = 0?
vesna_86 [32]
First you distribute the 3
(3x-12) (x+5)=0
then you set each equation equal to zero
3x-12=0 & x+5=0
then you solve for x
x =4, -5
