The multiplication of 3 and -4 on a number line is shown
<h3><u>Solution:</u></h3>
The number line representation is shown below
On number line the points are at equal distances
The multiplication of 3 with -4 can be understood in the following way:-
a × b , means a jumps b times
Eg :- 3 × -4 means 3 jumps -4 times
Which basically mean we are going to move 3 number per step , and we are going to do this 4 times and –ve sign indicates we will move in negative direction
Therefore,
So, when we move from 0 , when we take first step we reach -3 , in next step we reach -6 , in next we reach -9 and in the last step we reach -12
Which is the product 3 and -4 .i.e.
Use desmos:
This is the piece wise graph
The equation has exactly 1 real solution.
You can find this by solving it.
8 - 4x = 0 ----> add 4x to both sides
8 = 4x ----> divide both sides by 4
2 = x
You can see there is only 1 and therefore it has one solution.
Is that the question I think you have to add up the hours
Answer:
5.5
Step-by-step explanation:
9 = x + 3.5
do 9 - 3.5 and get 5.5
