Answer:
what is 1 6/10+5 2/10
=16/10 + 52/10 =
<u>16+52 = 68</u>
10 10
6/8-24/8
=6/8-20/8
<u>6-20 = 14</u>
8 8
6 6/10- 4 4/10
=<u>66-44 = 22</u>
10 10
Step-by-step explanation:
1/ if the fraction is mixed number example 2 1/7, it will be 2x7+1 and that will be 15 over 7
2/and if the bottom number example: 2 1/7, 7 is the bottom number and if 2 1/3 (3 is the bottom number) then see what the bottom number have in common example: 7-x1=7
7x2=14
7x3=21
3x1=3
3x2=6
3x3=9
3x4=12
3x5=15
3x6=18
3x7=21
so 21 is 7 and 3 have in common so the bottom number which is now 21 will divide 7 and got 3 and 3 will go on the top number 1 and 21 divide 3 which is 7 will go on the top number 1 and you continue to add your sum or subtract understand or not
A)
SLOPE OF f(x)
To find the slope of f(x) we pick two points on the function and use the slope formula. Each point can be written (x, f(x) ) so we are given three points in the table. These are: (-1, -3) , (0,0) and (1,3). We can also refer to the points as (x,y). We call one of the points
and another
. It doesn't matter which two points we use, we will always get the same slope. I suggest we use (0,0) as one of the points since zeros are easy to work with.
Let's pick as follows:
The slope formula is:
We now substitute the values we got from the points to obtain.
The slope of f(x) = 3
SLOPE OF g(x)
The equation of a line is y=mx+b where m is the slope and b is the y intercept. Since g(x) is given in this form, the number in front of the x is the slope and the number by itself is the y-intercept.
That is, since g(x)=7x+2 the slope is 7 and the y-intercept is 2.
The slope of g(x) = 2
B)
Y-INTERCEPT OF g(x)
From the work in part a we know the y-intercept of g(x) is 2.
Y-INTERCEPT OF f(x)
The y-intercept is the y-coordinate of the point where the line crosses the y-axis. This point will always have an x-coordinate of 0 which is why we need only identify the y-coordinate. Since you are given the point (0,0) which has an x-coordinate of 0 this must be the point where the line crosses the y-axis. Since the point also has a y-coordinate of 0, it's y-intercept is 0
So the function g(x) has the greater y-intercept
Look at the attachment for work
Quite simple, when asked for g(7) we look at 7 on the x axis (the # on the bottom) and go up to see where it is on the line.
For 7, we go between 6 and 8 and go up. It crosses the line at 4 therefore g(7) =4
Answer:
4.82
Step-by-step explanation:
0.000082 + 0.0004 = 0.000482 = 4.82
