Two ratios form a proportion if they are equal. If one fraction is equivalent to the other fraction, they form a proportion. To find out, reduce both fractions and see if they are equal.
A
1/2 and 4/2
Reduce 4/2 to 2/1.
1/2 and 2/1 are not equal.
1/2 and 4/2 do not form a proportion.
B
2/1 and 4/8
Reduce 4/8 to 1/2.
2/1 and 1/2 are not equal.
2/1 and 4/8 do not form a proportion
C
1/2 and 8/4
Reduce 8/4 to 2/1.
1/2 and 2/1 are not equal.
1/2 and 8/4 do not form a proportion
D
2/1 and 16/8
Reduce 16/8 to 2/1
2/1 and 2/1 are equal.
2/1 and 16/8 form a proportion.
Answer: D. 2/1 and 16/8
Answer:
222
Step-by-step explanation:
42/3 x 111/4 = (42 x 111)/(3 x 4)
42/3 x 111/4 = 2664/12
42/3 x 111/4 = 222
Answer:
More people died in Auschwitz than the British and American losses of World War Two combined. About 60 million Reichmarks - equivalent to £125m today - was generated for the Nazi state by slave labour at Auschwitz. Nazis at Auschwitz offered some non-Jewish female prisoners the option of 'light work
Step-by-step explanation:
The answer o this question would be:
<span>A.The vertical line test may be used to determine whether a function is one-to-one
</span><span>D. The horizontal line test may be used to determine whether a function is one-to-one.
Vertical and horizontal line test can be used to find out whether the function, not one-to-one. The test is done by making a horizontal line (for horizontal line test) or vertical line( for vertical line test). If there are no 2 or more points of the graph that touch the line in both tests, then the function would be one-to-one</span>
Y=m x+b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
