Answer:
It decreases
Step-by-step explanation:
Given the expression: 70-3g
- When g=1, 70-3g=70-3(1)=70-3=67
- When g=2, 70-3g=70-3(2)=70-6=64
- When g=3, 70-3g=70-3(3)=70-9=61
- When g=4, 70-3g=70-3(4)=70-12=58
- When g=5, 70-3g=70-3(5)=70-3=55
From the above, notice that as g increases, the value of the expression decreases.
Answer:
The solution to the given system of equations is (-2,
)
Therefore the values of x and y are x=-2 and 
Step-by-step explanation:
Given equations can be written as

Solving equation(2) we get
x=-2
Substitute x=-2 in equation (1) we get




Therefore the values of x and y are x=-2 and 
The solution to the given system of equations is (-2,
)

Answer:
(x + 4)(x - 3)
Step-by-step explanation:
x^2 + x - 12 = 0
In order to factorise an equation, one must take into consideration the factors of the values in given equation.
In the factored form, the above equation becomes
(x + 4)(x- 3)
Factors of x^2 = x times x
Factors of -12 = +4 x -3
As shown in the factored form above
