Minusing 9 from the previous answer and then getting a new answer
So you are trying to find out how many minutes Brain was billed for, so:
$18.41 - $5 =$13.41
since he gets billed 9 cents a minute he has to pay $13.41!!
Answer:
a:non linear
y-intercept=1
smallest postive x-intercept: π
y= 1 and x=0
Step-by-step explanation:
1.a:non linear
("Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value.")
2.The y-intercept is 1
The point where x is zero(0) is the y-intercept
(0,1)
3. smallest positive x intercept is
so x-intercept is point where y is 0
look at the paterns (pi,0) and (-pi,0) etc..
The smallest positive x-intercept is
(π,0)
4. The greatest value of y is y= 1 and x=0
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.
