Answer:
its none of these answers ;-;
Step-by-step explanation:
3^2 + 8 ÷ 2 - (4 + 3)
we do what's in parentheses first. (pemdas)
so now we have, 3^2 + 8 ÷ 2 - 7
next exponents, 3^2=9
9 + 8 ÷ 2 - 7
next division, 8÷2=4
9 + 4 - 7
next addition, 9+4=13
13-7
finally subtraction, 13-7=6
final answer: 6
Answer:
D
Step-by-step explanation:
The answer is b because if you look there is no Direct variation
Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
