Answer:
$14
Step-by-step explanation:
Sony paid for two scarves = $ 25
We are given that one scarf cost $3 more than the other
Let the cost of one scarf be x
So, cost of another scarf = x+3
Since the total cost is $25
So,
So, cost of one scarf = $11
Cost of another scarf = x+3=11+3=14
Hence the cost of the expensive scarf is $14
If a scatter plot has no association then it's ordered pairs have no predictable pattern.
195 is the answer because you replace x with 10
825-630=195
Scientific Notation: 4.88 ×10^7
Standard Form: 4.88 ×10^7
6.1×10^(-3) = 0.0061
8×10^9 = 8000000000
0.0061×8000000000 = 48800000
f(x) = 10x + 13
Function f(7) = 83
y = 10x + 13
Function f(7) = 10(7) + 13
y=1.4x+6.8
(-2;4) (-7;-3)
4=-2k+b
-3=-7k+b
7=5k
k=1.4
-2.8+b=4
b=6.8
I already know k and b so I can write an equation.
