Y=x-3
(4x-9)=x-3
+3 +3
4x-6=x
-4x -4x
-6=3x
-2=x
Y=4(-2)-9
Y=-8-9
y=-17
(-17,-2)
Answer:
x = -45.
Step-by-step explanation:
-x - y = 30
-x - 15 = 30
x + 15 = -30
x = -45
To check we are correct...
-(-45) - y = 30
45 - y = 30
-45 + y = -30
y = 15
So, x = -45.
Hope this helps!
B=1.25 so i think im not so good with this but i try if its wrong nvr listen to me
Answer: the above stated equation is a quadratic equation
Step-by-step explanation:
Given the following equations
y = x^2 + 5x - 3....equation 1
y-x = 2
y = x + 2........equation 2
Let equation 1 equal equation 2
x^2 + 5x -3 = x + 2
Bringing the equation to one side and equating to zero
X^2 +5x - 3 -x -2 = 0
X2 + 5x -x -3 -2 = 0
X^2 + 4x -5
Solving the aquatic equation
(x + 5)(x -1) = 0
X + 5 = 0
X1 = -5
X- 1 = 0
X2 = 1
To prove:
Substitute the values for x1and x2 into the equation x^2 + 4x - 5 = 0
