The answer is 10
Hope this helps have a nice day ;)
Answer:
the slope would be 5
Step-by-step explanation:
first, to find the slope, use the formula,
you're given two points, (6, 3) and (1, -22), so plug those numbers into the formula like so:
3--22/ 6-1
so,
3+22/ 6-1
25/5
and 25/5 is:
5
I have not done this in advance. I'm just going to write it down
and see what I can do with it:
[ 1/(x+3)² - 1/x² ] / 3
Multiply the top and bottom by (x+3)² :
[ 1 - (x+3)²/x² ] / 3 (x+3)²
Multiply the top and bottom by x² :
[ x² - (x+3)² ] / 3 x² (x+3)²
Now it's just a matter of expanding and cleaning things up,
and hope and pray that a lot of things cancel.
Eliminate the parentheses on top and bottom:
[ x² - x² - 6x -9 ] / 3 x² (x² + 6x + 9)
Combine the x² terms on top, and divide top and bottom by 3 :
[ - 2x - 3 ] / x² (x² + 6x + 9)
Finally, all I can make of this is:
- (2x + 3) / [ x(x+3) ]² .
That's not a whole lot prettier than the original form, but at least
we got rid of those fractions in the numerator of a fraction.
I hope this is some help to you.
Answer:
Rule #4
Step-by-step explanation:
'Im' needs an apostrophe because it is a contraction I'm means I am
Answer:
Step-by-step explanation:
From the diagram;
PQ+QS = PS.... 1 and
RS+ST = RT..... 2
From the qauestion we are told that PS = RT, PQ = ST
substitute this into both equationn1, it will become
ST+QS = RT.... 2
Subtract equation 3 from 2;
RS-QS +(ST-SST) = RT-RT
RS-QS+0 = 0
RS-QS = 0
add QS to both sides
RS-QS+QS = 0+QS
RS - 0 = QS
RS = QS (Proved)
