2^4 will equal 16
2x2x2x2
is 4x4 which equals 16
Answer:
Step-by-step explanation:
1. You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
2. Point-Slope Form: y - y1 = m(x - x1)
Standard Form: ax + by = c
5x - 2y = 10
-2y = -5x + 10
y = (5/2)x - 5 The slope is 5/2.
y - 2 = (-5/2)(x - 10)
y = (-5/2)x + 25 + 2
y = (-5/2)x + 27 The slope is -5/2.
y = (-5/2)x - 10 The slope is -5/2.
As a fraction: 20/7
As a mixed number: 2 6/7
OK. The first step is to find the amount the tank is losing per hour by balancing its gains and losses. Since it is gaining one gallon per hour but losing 1.5 gallons per hour, it is overall losing .5 gallons an hour. If there was originally 150 gallons in the tank, you can use the equation w=-.5h+150 to find the amount of water after h hours.
