Answer:
B
Step-by-step explanation:
Answer: the correct answer is ( 7 * 5 ) + (7 * 9 )
Step-by-step explanation:
7 * ( 5+9) = (7 * __) + ( 7 * __) = ( 7 * 5 ) + (7 * 9 )
Answer:
For each x increase of 1, the y increases by a common factor of 3. (second answer listed)
Step-by-step explanation:
Notice that you have not provided the graph that the problem involves, but from the description of what the y behavior is when x increases by one, one can deduct if an exponential pattern applies.
Out of the four examples given, only one of them represents an exponential growth. Such type of growth has to include a common multiplicative factor (the base of the exponent), since the function has to be of the form:
to be called exponential.
So every time that x increases by one unit, the following happens:
So notice that the original function ends up being just multiplied by the common factor "b".
The other options don't describe such behavior.
Answer:
Domain; [-1, 3)
Range; (-5, 4]
Step-by-step explanation:
The domain of a function is defined as the set of x-values for which the given function is real and defined. In order to find the domain of the graphed function, we have to determine the lowest and the highest x-values for which the function is defined. From the graph, the least value of x is -1 while the greatest x value is 3 but the function is not defined at this point. Therefore the domain of the function is;
[-1, 3)
On the other hand, the range refers to the set of y-values for which the function is real and defined. The least y-value from the given graph is -5 while the greatest y -value is 4. Therefore, the range of the graphed function is;
(-5, 4]
Answer:
50 muffins
Step-by-step explanation:
20 : 40%
y : 100%
y · 40 = 20 · 100
40y = 2000
40y ÷ 40 = 2000 ÷ 40
y = 50
