Answer:
A piecewise function.
Step-by-step explanation:
The problem you showed is a <em>piecewise function.</em>
In this problem, you have to plug in 3 for the value x.
However, if you take a look at the conditions that value x has, it never says that x can equal 3. <em>Thus, this function cannot be true.</em>
<em>Way to check this input is undefined: </em>
Plug in 3 for the variable x. On the first function, your output will be 4. On the second function, your output will be 8.
According to the definition of a function, a function can have many inputs but only one output. In this case, this function has one input, that is 3, but produces two outputs.
Answer:
A fact family is a set of related addition and subtraction number sentences that include the same numbers. The numbers 2, 4, and 6 can be written in two different addition sentences. The numbers 2, 4, and 6 can be written in two different subtraction sentences. These four number sentences make up a fact family.
Y= 3X + 1. Perpendicular means you would change the slope by flipping it and changing the sign. So the slope then becomes 3. Then you use your points to find the y-intercept by filling in the variables. 7=3(2) + B. 7=6 + B. Then subtract 6 from both sides. B=1. Then you just put your problem back into slope intercept form with your new slope and y-intercept. Y=3x + 1.
<h3><u>Question:</u></h3>
Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride
<h3><u>Answer:</u></h3>
Ricky has to further ride for 5 miles
<h3><u>Solution:</u></h3>
Given that, Ricky rides his bike 12 miles every day
Let "x" be the remaining distance in miles he has to ride further
Total distance = 12 miles
Also, given that he stops after 7 miles to rest
Therefore, already covered distance = 7 miles
Therefore, we can frame a equation as,
remaining distance + already covered distance = total distance
x + 7 = 12
Solve the above equation for "x"
x = 12 - 7
x = 5
Thus Ricky has to further ride for 5 miles
