Answer:
2 1/2
Step-by-step explanation:
1st, convert the fractions
2 2/3 = 2 4/6 = 16/6
5 1/6 = 31/6
31/6-16/6 = 15/6 = 2 3/6 = 2 1/2
True. because 2 and 4 are integers.
2/4= 1/2
once you can turn a number into a fraction. it is automaticly a rational number
Step:6x+12y-6z+7x+7y-28z
Answer:13x+19y-34z
For exponential functions
y=ab^x,
where
a is the scale vertical stretch factor,
b is the base, and
x the exponent (also independent variable)
It is a know fact that if the scale factor (1/2 or 2 in the answer choices) is positive, the graph is increasing if the base (3 or 1/3) is greater than 1.
This means that the base cannot be equal to 1/3. This eliminates choices 3 and 4.
Next, for a base greater than 1 (3>1), and the scale factor positive, it is a dilation (image gets bigger) if the scale factor is greater than 1. This eliminates the first choice where a=2.
This leaves us with the second choice where a=1/2, b=3, which is a shrink of the given exponential base function.
Answer:
0.25 is a decimal and 25/100 or 25% is the percentage for 2/8.
