Restaurant has an early bird special of $7 per plate before 4 PM. The regular price after 4 PM is $9 per plate. If the restaurant sold 93 plates and made $733, how many of those plates were early bird specials
Answer:
the early bird special plate is 52
Step-by-step explanation:
Let us assume the early bird special be x
And, regualr price be y
Now the equations are
x + y = 93
7x + 9y = 733
Now multiply by 7 in equation (1)
7x + 7y = 651
7x + 9y = 733
Now subtract these two equations
-2y = 82
y = 41
x = 93 - 41
= 52
hence, the early bird special plate is 52

What is the domain in interval notation of f(x)=(x+3)^2
Given:
The function is
[tex]f(x)=(x+3)^2[/tex]
To find:
The domain of the given function in interval notation.
Solution:
We have,
[tex]f(x)=(x+3)^2[/tex]
Domain is the set of x-values or input values.
The given function is a quadratic function and domain of the quadratic function is all real number. The function is defined for all values of x. So, domain of the given function is the set of all real numbers.
Domain = Set of all real numbers
Domain = (-∞,∞)
Therefore, the domain of the given function is (-∞,∞).

Your cat is 8 years younger than your friend. In 4 years, your friend will be twice as old as your cat. How old is your cat now?
years old
Answer:
your cat will be 12 your friend will be either 16 or 24
Step-by-step explanation:
Friend is 12 years old and cat is 4 years old.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.
Given,
Cat is 8 years younger than your friend
Let age of friend be x
then, age of cat be x - 8
But In 4 years, your friend will be twice as old as your cat
x + 4 = 2(x - 8 + 4)
x + 4 = 2x - 16 + 8
x + 4 = 2x - 8
-2x + x = - 12
x = 12
Age of friend = 12 years
Age of cat = 12 - 8 = 4 years
Hence, 12 years is age of friend and 8 years is age of cat.

Answer:
Option A is correctStep-by-step explanation:
Given functions f(x) and g(x). f(x) is:
f(x) = x^2 + 4x + 6Converted into vertex form, it is:
f(x) = (x + 2)^2 + 2g(x) has vertex at (-2, -14), it's vertex form is:
g(x) = (x + 2)^2 - 14Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).
Both have positive leading factors, therefore the vertex is their minimum point.
Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.
Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.
Correct choice is A
