Answer:
7/2 or 3.5
Step-by-step explanation:
The y-axis represents the cost is dollars. The x-axis is the amount of gasoline in gallons. To find the cost in dollars per gallon, choose a point on the graph, and divide the dollars (y-coordinate) by the gallons (x-coordinate).
cost = (21/4) / (3/2)
cost = 21/4 * 2/3
cost = 42/12
cost = 7/2 = 3.5
Answer:
a = <u>2 - 3b</u>
2
Step-by-step explanation:
3(a + b) = a + 2 expand
3a + 3b = a + 2
3a - a = 2 - 3b
2a = 2 - 3b
a = <u>2 - 3b</u>
2
Answer:
5,00000000
Step-by-step explanation:
6000000000
Answer:
A.
Step-by-step explanation:
Slope = y2-y1/x2-x1
(2,-4) = (x1,y1)
(4,2) = (x2,y2)
Slope = (2+4)/(4-2)
= 6/2
= 3
Y=mx+b [Plugging (4,2) into this]
2 = 3×4 +b
2 = 12 + b
b = -10
The surface area of that pyramid is 192 cm^2
