Step-by-step explanation:
Distance = speed x time = 60 x 12 = 720 km. Speed = 72 km / h
Imagine what the graph would look like. Does it open upwards or downwards?
5x - 1 has a positive slope of 5 and it is reflected horizontally. The graph would be shaped like a V. A limited segment, or none, of the graph is below a certain value of y, and the rest outside it is above.
Hence, the solution must be a < x < b.
|5x - 1| < 1
5x - 1 < 1
x < 2/5
|5x - 1| < 1
5x - 1 > -1
x > 0
0 < x < 2/5
Answer: A, x = square root of 60.
Step-by-step explanation:
Use the Pythagorean Theorem, a^2 + b^2 = c^2.
8^2 = 2^2 + x^2
x^2 = 8^2 - 2^2
x^2 = 64 - 4
x^2 = 60
x = sqrt of 60
This cannot be solved unless you provide the picture for further answering.
Answer:
22.5 weeks
Step-by-step explanation:
y = 1.12x + 28.78 represents the height of the puppy. Here that height is 54 cm:
Then 54 = y = 1.12x + 28.78
Combining the constants, we get 1.12x = 25.22. Dividing both sides by 1.12, x turns out to be 22.5 weeks.
