Systems of linear equations can only have 0, 1, or an infinite number of solutions. The two lines can't intersect twice, so the correct answer is that the system has one solution.
Answer:
C) 7×10^8/(5×10^3)
Step-by-step explanation:
In cubic inches, the volume of a bucket of sand is ...
(π/4)(20 in)²(15 in) = 1500π in³ ≈ 5×10^3 in³
__
The volume of the warehouse is
(250 ft)(80 ft)(20 ft) = 400,000 ft³ = 4×10^5 ft³
The conversion to cubic inches is ...
(4×10^5 ft³)(1728 in³/ft³) = 4×1.727×10^8 in³ ≈ 7×10^8 in³
Dividing the warehouse volume by the bucket volume gives the approximate number of buckets that will fit in the warehouse:
(7×10^8)/(5×10^3) . . . . . matches choice C
Answer:
D) g(x) is shifted 3 units to the left and reflected over the x-axis
Step-by-step explanation:
The reflection -f(x) indicates a reflection in the x-axis. <u>+</u> means that it shifts to the left.
Every value is multiplied by 4 so:
1/16, 1/4, 1, 4, 16, 64, 256, 1,024, 4,096, 16,384.
Therefore, 16,384 is the 10th term.
Answer:
r = -2.
Step-by-step explanation:
-13r+ 20r = -14
7r = -14
r = -14/7
r = -2.
