Answer:
The correct options are:
Option B)
is never zero.
Option F) When x=0, y≠0
Step-by-step explanation:
Consider the provided function.

When we substitute x=0 in above function we get:


When we substitute x=-1 in above function we get:


When we substitute x=1 in above function we get:


The above function is exponential function which does not pass through the origin and the range of the function is a positive number.
The graph of the function is shown in figure 1.
Now consider the provided options.
Option A)
is always greater than or equal to 1.
The option is incorrect as the value of the function is less than 1 for negative value of x.
Option B)
is never zero
The option is correct.
Option C) When y=0, x=0
The option is incorrect.
Option D) When x=0, y=4
When x=0 the value of y is 1.
Thus, the option is incorrect.
Option E)
is zero when x=0
When x=0 the value of
is 1.
Thus, the option is incorrect.
Option F) When x=0, y≠0
The option is correct as 0≠1.
Answer:
The type of method is convenience; he isn't posting advertisements to volunteer(self-selected) and he isn't following an algorithm(systematic), therefore, he's using convenience.
Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex. Adjacent angles share a common ray and do not overlap. The size of the angle xzy in the picture above is the sum of the angles A and B.
Answer:
Discount is $2.70
After-discount price is $15.30
Step-by-step explanation:
To get the after-discount price, multiply $18 by (1.00 - 0.15), or, in other words, multiply $18 by 0.85. The after-discount price is $15.30.
Two ways to find the discount: one is to multiply $18 by 0.15; the other way is to subtract $15.30 from $18.
