I think it should be option d
Answer:
(1.25, - 5 )
Step-by-step explanation:
Given the 2 equations
- 4x + 3y = - 20 → (1)
4x + 2y = - 5 → (2)
Adding the 2 equations term by term will eliminate the x- term
5y = - 25 ( divide both sides by 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (2)
4x + 2(- 5) = - 5, that is
4x - 10 = - 5 ( add 10 to both sides )
4x = 5 ( divide both sides by 4 )
x =
= 1.25
Solution is (1.25, - 5 )
Answer:
A.
Step-by-step explanation:
The given equation is

We solve for y by subtracting 3x from both sides to obtain;

We now divide through by -7 to get;

This simplifies to;

This equation is now in the form y=mx +c, where
is the slope.
The answer is 14
-18/6 is -3. add that to 17 and you get 14.
