PEMDAS!!
or an easy way to remember it is Please Excuse My Dear Aunt Sally
which stands for Parentheses, Exponent, Multiplication, Division, Addition, and Subtraction Go in order from p to s from left to right as you would read it
Parentheses first (9-3^2) start with the exponent 3^2=9 then subtract
(9-9)=0 so now we have 2+6(0)-2 Multiply next so 6(0)=0 then we have 2+0-2
next add 2+0=2 then we have 2-2 then subtract 2-2=0 so the overall answer is 0
but you have multiply, added, and subtracted throughout the process

Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
Answer:
Choice D.
Step-by-step explanation:
- Since the graph is translated down 4, it cannot be choice A. or C.
- Since the graph is concave up, choice B. is ruled out.
- Leaving choice D. the correct answer.
Answer:
the answer is x=185
Step-by-step explanation:
x+240=425
-240 -240
x= 185
