Problem 4:
4a = -15
4b = -75
4c = 125
Problem 5:
5a = -5
5b = 95
5c = -19
Step-by-step explanation:
<em> See attached for my work. </em>
For problem 4, we substitute the different values given for x and solve.
For problem 5, we set the function equal to the given values and solve.
Looking at the question we can see that it says:
We should know what these symbols mean:
stands for something less than the other, for example:
We can say that 2 is less than 5 so in a symbolic form it can be written as,
Similarly,
stands for something greater than the other, for example:
We can say that 7 is greater than 5, in a symbolic form it can be written as,
So here, means that, 42153 is greater than 35214.
Answer:
Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:
