Answer:
x= 8
Step-by-step explanation:
17x + 3 = 139
17x = 136
x = 8
The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.
That is: x = 2(-1) - 1
= -2-1
= -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,
y = (-1)∧-3
= -1
The point that correspond to t=-1 is (-3,-1).
Answer:
242 cm^3
Step-by-step explanation:
Volume of a pyramid = 1/3 * area of base * height
= 1/3 * 60.5 * 12
= 242 cm^3
