Answer:
For all real numbers a except 0, we have
a(1/a) = 1
Step-by-step explanation:
Multiplication of real numbers are having the following properties:
i) commutative = ab = ba
ii) associative a(b+c) =ab+ac
iii) Multiplicative identity element exists such that for any number
a*1 =1*a = a
i.e. 1 is identity.
Inverse property is for any a not equal to 0, we have a real number such that
a*that real number = multiplicative identity
i,.e. a(a real number) = 1, a not equal to 0
In other words, there exists an 1/a for all a not equal to 0 satisfying a*1/a = 1
Answer:
1. 80%.
2. 2 quarters, 3 dimes, 4 nickels, 30 pennies. (if you don't use pennies make it 6 dimes.)
Answer:
4.50 is for two scoops and a normal cone. Upgrades on cone is $0.50 and any additional toppings are also $0.50
the slope intercept form is y=mx+b
since the line intersects at (0,3) b= 3
since the slope is 0 m= 0
so the equation would be y=0x+3 or y=3
First find the slope(m)
Slope= y2-y1/x2-x1= (1-(-5))/(-1-(-2))= 6/1 = 6
Then find the y intercept (move up six and right one from (-1, 1) to get (0, 7)
The y-intercept is y=7
Now make the equation
Y= slope(x) + y-intercept
Y=6x+7
