Answer:
1. x = no solution
y = no solution
2. x= 3
y = -4
Step-by-step explanation:
y = 5 - x
2x + 2y = 6
Divide the equation by 2.
x + y = 3
x + (5 - x) = 3
x + 5 -x = 3
x-x + 5 =3
5 =3 ⇒⇒⇒ This is not true. So, we can say that the simultaneous equation don't have a solution.
-7x - 2y = -13
x - 2y = 11
x = 11 + 2y
-7(11 + 2y) - 2y = -13
-77 - 14y - 2y = -13
-16y = 64
y = -4
x = 11 + 2(-4)
= 11 - 8 = 3
I think the answer's a 20/6. Hope this helps
Answer:
f(x) = √-x
Step-by-step explanation:
f(x) = √-x
Step 1: Obtain the value of x (start)
Step 2: The square root of -x
Step 3: Write down the value of f(x) (End)
5x + 13y = -13
13y = -5x - 13
y = -5/13x - 13/13
y = -5/13x - 1
Slope = -5/13
y-intercept = -1
