Answer:
yes
Step-by-step explanation:
To determine if (- 8, - 7 ) is a solution to the equation
Substitute the values of x and y into the equation and if both sides are equal then it is a solution.
left side : 3(- 8) + 10 = - 24 + 10 = - 14
right side : 2y = 2(- 7) = - 14
Since both sides are - 14 then (- 8, - 7 ) is a solution to the equation.
Answer:
Step-by-step explanation:
A. In this case, they can be arranged at any order. Since there are 7 people all in all, therefore the number of arrangements is:
number of arrangements = 7P7 = 5040 ways
B. In this case, only the 5 people can be arranged in any order therefore 5P5. However the groom and bride can be interchanged on 2 places, therefore:
number of arrangements = 5P5 * 2 = 240 ways
C. In this case, only the 5 people can be arranged in any order while the groom and bride can no longer be interchanged, therefore:
number of arrangements = 5P5 = 120 ways
