Step-by-step explanation:
If in any set, you can find 2 or more points that lie on the same vertical,
then it is NOT a function, that is, the same value of x yields 2 or more different
values of y, you don't have a function.
e.g. D is definitely not a function. You have (-2,4) and (-2,-4) , the same x of -2 giving you a y value of 4 and -4.
1. Answer is 4.5 km / hr.
... because you divide the time but the distance so for this question you divide 22.5 by 5 and that's your answer. do the same for every question! hope this helps.
Answer:
$13
Step-by-step explanation:
Let's set up a ratio...
2:3.25
8:x
We know 2*4 is 8 so we need to multiply 3.25 by 4 to get x...
3.25*4=$13
Answer:
Step-by-step explanation:
Given: The inequality is 
where t represents the temperature. A number line going from to 
.
To find: Solutions of the inequality
Solution:
A number line is a line on which numbers are marked at equal intervals, used to show simple arithmetic operations.
An inequality is a mathematical relationship that compares two values to show less than or equal to, less than, not equal to, greater than, greater than or equal to.
In the given question solution of the inequality is as a number line is going from to .
5.56 is your answer because you multiply 2.78 times 2 to get the absolute value.
