Answer:
Ur question is wrong..
Step-by-step explanation:
In a survey of 100 people, 60 like farming and 65 like civil service?
<u>60+65=125</u>..?
Answer:
D
Step-by-step explanation:
Answer:
The first one:
−8x4−14x2−3
Step-by-step explanation:
(-4•2-1)(2•2+3)
-4•2 = -8
-8 - 1 = -9
(-9)(2•2+3)
2•2 = 4
4+3 = 7
(-9)(7) = -63
Now we find the one that equals -63:
-8•4-14•2-3
(-8•4)-14•2-3
-32-14•2-3
-32-(14•2)-3
-32-28-3
(-32-28)-3
-60-3
-60-3 = -63
BAM! THE ANSWER!
For this case we have that by definition, the slope of a line is given by:
![m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7By_%20%7B2%7D%20-y_%20%7B1%7D%7D%20%7Bx_%20%7B2%7D%20-x_%20%7B1%7D%7D)
Where:
and
are two points through which the line passes.
According to the image we have:
![(x_ {1}, y_ {1}): (-5,3)\\(x_ {2}, y_ {2}): (3, -3)](https://tex.z-dn.net/?f=%28x_%20%7B1%7D%2C%20y_%20%7B1%7D%29%3A%20%28-5%2C3%29%5C%5C%28x_%20%7B2%7D%2C%20y_%20%7B2%7D%29%3A%20%283%2C%20-3%29)
Substituting we have:
![m = \frac {-3-3} {3 - (- 5)} = \frac {-6} {3 + 5} = \frac {-6} {8} = - \frac {3} {4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7B-3-3%7D%20%7B3%20-%20%28-%205%29%7D%20%3D%20%5Cfrac%20%7B-6%7D%20%7B3%20%2B%205%7D%20%3D%20%5Cfrac%20%7B-6%7D%20%7B8%7D%20%3D%20-%20%5Cfrac%20%7B3%7D%20%7B4%7D)
Thus, the slope of the line is:
![m = - \frac {3} {4}](https://tex.z-dn.net/?f=m%20%3D%20-%20%5Cfrac%20%7B3%7D%20%7B4%7D)
Answer:
![m = - \frac {3} {4}](https://tex.z-dn.net/?f=m%20%3D%20-%20%5Cfrac%20%7B3%7D%20%7B4%7D)
