Well there are 180 degrees in a circle, so the equation should look like this 180/45 and the answer is 4
hope this helps you :D
Answer:
y=6-3x
Step-by-step explanation:
first subtract 9x from 9x+3y=18
-9x -9x
so you get 3y=18-9x or 3y=-9x+18 then divide both sides by 3
so you get y=6-3x hope this helps :)
The opposite of 17.2 from 0 on a number line would be -17.2.
Answer:
1. 
2. 
Step-by-step explanation:
Let the number of people in the group be x. Denote the total cost as C.
1. If the regular cost is $21 per person, then the total regular cost for x people is 
2. If the special cost is $8 per person, then the total special cost for x people is
There is an additional $104 fee for a private room, thus the total special cost is 
Answer:
x=±1. are the factors of the quadratic equation.
Step-by-step explanation:
Given quadratic expression, f(x)=-12x - 2x + 60x² +14x-60
Rearranging and adding the terms in the expression and equating to zero.
f(x)= 60x² -60=0
60(x² - 1) =0
The zero product property states that if the product of a⋅b=0 then either a or b equal zero or both of them must be equal to zero. This basic property helps us solve the quadratic equations like (x+2)(x-5)=0 where x =-2,5.
from the zero product property we can infer that 60≠0⇒x² - 1=0
⇒(x+1)×(x-1) = 0
⇒x=±1.
Therefore, x=±1. are the factors of the quadratic equation.
