1=2=2=3=4=4=++1+1+2+3+4+ CHEESE
Answer:
look on quizlet and go to Geometry chapter 2 flashcards.
Step-by-step explanation:
p= popcorn
x=number of kids in class
c= cost
Plug in data:
c = px
31.5=1.5x
Divide both sides by 1.5:
21= x
There are 21 kids in the class.
To find the function, we can try to find the slope intercept form of the table.
Let's use the points (1,-1) and (2,-3) to find the slope.
Slope formula: rise/run
(-3 - - 1)/(2 - 1) = -2/1 = -2
Slope = -2x
Y-intercept = 1
y = -2x + 1
We can plug in a coordinate to check.
Let's use (2,-3).
-3 = 2x + b
Plug in the slope.
-3 = 2(-2) + b
-3 = -4 + b
4 + -3 = 1
b = 1
Therefore, the answer is f(x) = negative 2x + 1.
180-65=3x-10+2x
180-65+10=3x+2x
125=5×
25=x
AngleB= 3•25-10=65
AngleC= 2•25=50
