Answer:
-a^2 + -4a + 3a + 12
Step-by-step explanation:
FOIL
First terms: -a x a = -a^2
Outside terms: -a x 4 = -4a
Inside terms: 3 x a = 3a
Last terms: 3 x 4 = 12
Answer:
Step-by-step explanation:
The rate of change of the situation is known as the slope:
Slope = Δy/Δx
Slope = y2-y1/x2-x1
From the graph, x2 = 10.5, x1 = 0. y2 = 32, y1 = 0
Slope = 32-0/10.5-0
Slope = 32/10.5
Slope = 3.047
Hence the rate of change is 3.047 ounces per minutes and the situation represents the slope of the graph.
1/2 = 0.5 = 50% was found.
Looking at the scale, there are 5 dashes from 0 to 10,000. This means that each dash is worth $2,000. The thermometer is marked 2.5 dashes up; 2.5(2000) = 5000.
5000/1000 = 1/2; 1/2 = 0.5; 0.5 = 50%.
Answer:
h = 12.5
Step-by-step explanation:
Simplifying
h + 3h + 4h = 100
Combine like terms: h + 3h = 4h
4h + 4h = 100
Combine like terms: 4h + 4h = 8h
8h = 100
Solving
8h = 100
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '8'.
h = 12.5
Simplifying
h = 12.5
Add the two numbers and divide by 7. 285.38 + 353.47 = 638.85, to figure out how much total laundry they did each day you divide by 7 since there are 7 days.
Final answer: 91.264 pounds of laundry
