Answer:

the ratio in lowest terms is: 7 knives to 8 spoons = 7/8

Step-by-step explanation:

First express the ratio 105 knives to 120 spoons as the quotient:

\frac{105}{120}

next write each of the numbers in prime-factor form:

105 = 3 x 5 x 7

120 = 2 x 2 x 2 x 3 x 5

Now notice that when we express the quotient sing the factor form of the numbers, the factor 3, and 5 can be cancelled out because they appear in numerator an in denominator at the same time. therefore our quotient becomes:

\frac{105}{120} =\frac{3*5*7}{2*2*2*3*5} =\frac{7}{2*2*2} =\frac{7}{8}

Therefore the ratio in lowest terms is: 7 knives to 8 spoons

xeze [42]
The coordinates of points in the graph are,

(-4,-1), (-2,1), (0,-3), (2,3)
and

(4,-2)
Any other point whose first coordinate(the x-co-ordinate) coincides with one of these points will make the relation not a function.

The relation becomes one- to-many relation which is not a function.

It will also fail the vertical line test , if the points are connected with line segments.

One of such point is,
