The first one [f(x) = 6x + 9] because “f(x) is y” and all you do is rearrange the equation
Answer:
Step-by-step explanation:
The Earth, Sun and Moon form a right triangle.
By the definition of cosine in a right triangle we can write that
cos x ° = adjacent side /hypothenuse = y/ distance Moon Sun
Since we measured the angle x, and the distance y we can use algebra to find the unknown distance between the moon and the Sun.
distance Moon Sun = y/cos x°
Answer:
B -9<x-4 <9
Step-by-step explanation:
|x-4|<9 ➡ -9 < x-4 < 9
-5 <x <13
Answer:
y=mx+c
y=2x+9
Step-by-step explanation:
Slope(m)=2, y-intercept(c) =9
Substitute in the equation y=mx+c
Answer:
Option A. 
Step-by-step explanation:
Let
t ------> the number of additional toppings
c ----> the cost of the pizza in dollars
we know that
The linear equation that represent this situation is

This is the equation of the line in slope intercept form
where
the slope m is equal to

the y-intercept b is equal to
-----> the cost of a pizza without topping
