Is the line through points p(-7,8) and q(-5,-6) parallel to the line throuh points R(3,-5) and S(-2,0)? explain.
BARSIC [14]
I'm going to use the slope formula which is
m = (y2 - y1)/(x2 - x1)
where (x1,y1) and (x2,y2) are the two points the line goes through

Slope of line PQ
m = (y2 - y1)/(x2 - x1)
m = (-6 - 8)/(-5 - (-7))
m = (-6 - 8)/(-5 + 7)
m = (-14)/(2)
m = -7
The slope of line PQ is -7

Slope of RS
m = (y2 - y1)/(x2 - x1)
m = (0 - (-5))/(-2 - 3)
m = (0 + 5)/(-2 - 3)
m = (5)/(-5)
m = -1
The slope of line RS is -1

Because the slopes are NOT equal (one is -7 and the other is -1), this means the lines are NOT parallel.

-----------------------------------------------------------------------------------------------------

Answer: Choice B) No, the lines have unequal slopes

Find the sum or difference (5b-9)-3(8-2b)
True [87]
<span>Simplifying (5b + -9) + -3(8 + -2b) = 0 Reorder the terms: (-9 + 5b) + -3(8 + -2b) = 0 Remove parenthesis around (-9 + 5b) -9 + 5b + -3(8 + -2b) = 0 -9 + 5b + (8 * -3 + -2b * -3) = 0 -9 + 5b + (-24 + 6b) = 0 Reorder the terms: -9 + -24 + 5b + 6b = 0 Combine like terms: -9 + -24 = -33 -33 + 5b + 6b = 0 Combine like terms: 5b + 6b = 11b -33 + 11b = 0 Solving -33 + 11b = 0 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '33' to each side of the equation. -33 + 33 + 11b = 0 + 33 Combine like terms: -33 + 33 = 0 0 + 11b = 0 + 33 11b = 0 + 33 Combine like terms: 0 + 33 = 33 11b = 33</span>

a pond is being dug according to plans that have a scale of 1 inch= 6.5 feet. The maximum distance across the pond is 9.75 inche
cestrela7 [59]

We are given a scale that for every 1 in on the plan, the actual length will 6.5 ft. 

The maximum distance across the pond on the plan is 9.75 in. So that means we will need to take 6.5 ft 9.75 times. So our answer is 

6.5*9.75=63.375 ft. That's the answer. 

We can visualize this a different way

1 in = 6.5 ft

9.75 in = x ft

And from here it's a little more clear to see what needs to be done. 

Hope this helped!
