Let the number of students who chose tiger be x.
The number of students who chose bulldog is 4 * x.
The number of students who chose lion is 2 * x.
7x = 273
x = 273/7 = 39
Your answer would be:
2 * x = 78.
hope this helps! :))
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
Answer:
this table is linear
Step-by-step explanation:
it's linear because there is a common difference of -4
.452
you can just move the decimal when you are dealing with 10 or 100
