The probability should be 50/50
Explanation:
Because each time you roll a dice it’s a 50/50 chance to get any number regardless of the number they roll on
Answer:
y=-7
Step-by-step explanation:
This is an expression, not an equation. y is -7 for any value of x, so f drops out of the equation and it beomes an expression.
Answer:
a = 3, b = 1, c = - 3
Step-by-step explanation:
Substitute n = 1, 2, 3 into the n th term
a + b + c = 1 → (1)
4a + 2b + c = 11 → (2)
9a + 3b + c = 27 → (3)
Subtract (1) from (2) term by term to eliminate c
Subtract (2) from (3) term by term to eliminate c
3a + b = 10 → (4)
5a + b = 16 → (5)
Subtract (4) from (5) term by term to eliminate b
2a = 6 ( divide both sides by 2 )
a = 3
Substitute a = 3 into (4) and evaluate for b
3(3) + b = 10
9 + b = 10 ( subtract 9 from both sides )
b = 1
Substitute a = 3, b = 1 into (1) and evaluate for c
3 + 1 + c = 1
4 + c = 1 ( subtract 4 from both sides )
c = - 3
Then a = 3, b = 1 and c = - 3
The first step is to do the distributive property to get rid of the parenthesis...youd end up with:
2x + 14 = 36
Answer: The system of equations have many solutions and the correct options are A,B and D.
Explanation:
The given equations are,
..... (1)
.... (2)
Simplify the second equation.


Divide both sides by 3.

It is same as equation (1). Since equation (1) and (2) are same, therefore all the points lies on the line or which satisfies the equation are the solution of the given system of equations.
Test the points whether the point lies on the line or not.
Check for point A(6,-7).


LHS and RHS are equal, therefore the point A is the solution of the system of equations.
Check for point B(2,1).


LHS and RHS are equal, therefore the point B is the solution of the system of equations.
Check for point C(-2,-9).


LHS and RHS are not equal, therefore the point C is not the solution of the system of equations.
Check for point D(-4,13).


LHS and RHS are equal, therefore the point D is the solution of the system of equations.
Therefore the options A,B and D are correct.
