42/2 is 21 then add 9 you’d get 30 as your final solution.
Answer:
Refer to explanation^
Step-by-step explanation:
As stated in the solution, 3/7 is a negative fraction.
To make it less confusing,
2/7 x (-3/7)
Multiply the numerator with the other numerator and the denominator multiply with the other. Like...
2 multiply 3 = 6 (numerator)
7 multiply 7 = 49 (denominator)
Since the 2nd fraction is a negative, the answer is negative too.
If you convert the fraction to a decimal, it gives -0.1224489796
We want to find a graph that represents Noah's average speed.
We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:
s = 12ft/6s = 2ft/s
Then we can define a linear equation:
y = (2ft/s)*x
As the distance that Noah travels in x seconds.
The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.

In my opinion the answer is <span>m2 – 100 = –99
proof
</span>m2 – 100 =<span>(m – 10)(m + 10)
for eg. m=1, </span>(-9)(11)= <span>–99</span>
