Answer:
{y | y = –7, –1, 0, 9}
Choice B is correct
Step-by-step explanation:
The range of a function y = f(x) refers to the set of y - values for all values of x for which the function is real and defined.
The set of y values from the given table is;
–7, –1, 0, 9
Therefore, the range of the given function is;
{y | y = –7, –1, 0, 9}
Answer:
7x² + 9x + 6y
Step-by-step explanation:
7x² + 4x + 5x + 8y - 2y
Let the number of orders Eric served be x
Eric = x
Mai = x+ 8 [Mai served 8 more than Eric]
Dean = 3x [Dean served 3 times as many as Eric]
Given that the total is 103
x + x + 8 + 3x = 103
5x + 8 = 103
5x = 103 - 8
5x = 95
x = 19
x = 19
x + 8 = 19 + 8 = 27
3x = 19 x 3 = 57
Eric served 19
Mai served 27
Dean served 57
The zeros of the equation are A) x = -5 and x = 2
Step-by-step explanation:
The equation given is
Which is a second-order equation written in the form
where here:
a = 1
b = +3
c = -10
The solutions (the zeros) of an equation wirtten in this form can be found by using the following:
Substituting the values of a, b and c for this equation, we find:
Which gives two values:
x = -5
x = 2
Therefore, these values are the zeros of the equation, so the correct option is
A) x = -5 and x = 2
