Answer:
bc=cb
It is an example of commutative property.
Step-by-step explanation:
The given expression
By cross multiplying we can write given expression as
a+b=b+a
We can write commutative property in multiplication
ab=ba
Therefore, by using commutative property then we get
bc=cb
Hence, the given expression is an example of commutative property.
the equation (y-3)^2 =4y-12
y = -7
Answer:
32 foot-long hot dogs will be served
Step-by-step explanation:
The total number of "ratio units" is 3+2 = 5. If 5 units stand for 80 hot dogs, then each ratio unit represents 80/5 = 16 hot dogs.
The number of foot-long hot dogs that will be served is 2×16 = 32.
passes through the point (3, 2).
Answer:
Y= 3x-7
Step-by-step explanation:
Since the line is parallel , the slope is same i.e. 3 .
now the equation should be y= Mx + b where m is the slope and c is the y-intercept
plugging the value of m=3 and ( 3,2) into the equation
2= 3(3) + c
2= 9+ c
c= -7
hence the equation of the line is y=3x-7
Step-by-step explanation:
It is given that, the vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function as :
Where
15 is the initial height of the overhang
-10 is the initial vertical velocity
t is in second
We need to find the time taken by the snowboarder to land after jumping off the overhang. At this condition,
h(t) = 0
So,
On solving above equation using online calculator, we get the value of t = 0.705 seconds. So, the time taken by the snowboarder to land after jumping off the overhang is 0.705 seconds.
