Answer:
The integers are 4 and 7 or -2 and 1.
Step-by-step explanation:
You can make a system of equations with the description of the two integers.
1. x = y + 3
2. 2x + 2 = y^2
The simplest and the fastest way to solve this system in this case is substitution. You can substitute x for y + 3 in the second equation.
1. x = y + 3
2. 2(y + 3) + 2 = y^2
Now simplify and solve the second one. For convenience, I will just disregard the first equation for now.
2y + 6 + 2 = y^2
y^2 - 2y - 8 = 0
You can factor this equation to solve for y.
(y - 4) (y + 2) = 0
y = 4, y = -2
Now we can substitute the value of y for x in the first equation.
x = 7, x = 1
4*6*8=192
So they can have 192 choices for the pizza
Answer with explanation:
Given : Number of men = 4
Number of women = 6
Total people = 
Total number of ways to make a committee of five people from 10 persons :-
a) Number of ways to make committee that has exactly four women :
The probability that committee has exactly four women :
b) Number of ways to make committee that has at-least four women :
The probability that committee at-least four women :
c) Number of ways that committee has more than 4 women :-
The probability that committee has more than 4 women :-
Now, the probability that committee has at most four women :-
Step-by-step explanation:
let the first number be x
let the second number be y
½ of the first number= ½x
Double the second; 2*y=2y
the sum... that is ½x+2y=14
Answer:
-3 units / s/s.
Step-by-step explanation:
Acceleration = change of velocity / time
= 0 - 12 / 4
= -3 units /s/s.
Note: negative acceleration = deceleration.
