Answer:
-135/14
Step-by-step explanation:
There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...
-67/7 = -9 4/7 = -9.571428... (repeating)
-78/8 = -9 3/4 = -9.75
So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.
If you like, you can convert these numbers to ones with a common denominator (56).
-67/7 = -536/56
-78/8 = -546/56
These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.
Step-by-step explanation:
f(x)=3x²-3x
f(-3)=3(-3)²-3(-3)
=3(9)+9
=27+9
=36
g(x)=5x-1
g(-7)=5(-7)-1
=-35-1
=-36
Answer:
Step-by-step explanation:
It is given that,
Distance covered, 
Time taken, 
We need to find the rate in miles per hour. It can be calculated by dividing distance covered and time taken as follows :
Hence, Dev jogs at the rate of 
.
