you can subtract from point 1 to point 2
(9,-2) - (8,3)
9-8= 1
-2-3= -5
therefore horizontal leg is 1
vertical leg is -5
you can also sketch and count the units :)
This is a linear programming question
if u want to solve the question, u can plot a graph(see the picture)
while x is n, y is r
and u may find out all of the integral values of x ,y in the required region, and sub them to 6450x+7150y=c, where c is the overall customers number, see which point give u the largest number of customers, u may get the ans then
A.true
Because congruent angles are exactly the same measure
Let
Y=the food is yummy
O=overeat
E=exercise
Note:
∪ = or
-> if ... then
(Y∪O)->E
