4 to 7 = 4/7
5/8 is not.
12/20 = 6/10 = 3/5 . It is not equivalent.
8:14 = 4 : 7 . It is equivalent
5 to 10 = 1 to 2. It is not.
16/28 = 8/14 = 4/7. It is equivalent.
9 to 16 = 9 to 16. It is not equivalent.
So only 8:14 and 16/28 are equivalent to 4 to 7.
Answer:
y=4x+6
Step-by-step explanation:
when x=0 y=6
when x=1 y=10
when x=2 y=14
to find y=50:
50=4x+6
44=4x
11=x
x=11 when y=50
Answer:
W is not a subspace.
Step-by-step explanation:
Notice that (-1,2,2) and (-1,5,3) are both elements of W. Because its x coordinate, x = -1, satisfy the condition |x| = 1.
but (-1,2,2) + (-1,5,3) = (-2,7,5) do not belongs to W. Because its first coordinate, x =-2, do not satisfy |x| = 1.
Answer:
12 * 3x
Step-by-step explanation:
x is equal to the minutes
Step-by-step explanation:
7. Since they are similar triangles we have:

So DF is 15
8. They are also similar. So:

So PR is 10
