Answer:
3x+7=10x
Step-by-step explanation:
you are just adding 7+3 then you add the vairable term
Answer:
-2
Step-by-step explanation:
Let's plug your functions f(x)=x^2-2x and g(x)=6x+4 into (f+g)(x)=0 and then solve your equation for x.
So (f+g)(x) means f(x)+g(x).
So (f+g)(x)=x^2+4x+4
Now we are solving (f+g)(x)=0 which means we are solve x^2+4x+4=0.
x^2+4x+4 is actually a perfect square and is equal to (x+2)^2.
So our equation is equivalent to solving (x+2)^2=0.
(x+2)^2=0 when x+2=0.
Subtracting 2 on both sides gives us x=-2.
180= x+24+6x+18+2x+30
180= 9x+72
108=9x
X=12
Find slope: (y2-y1)/(x2-x1)
(-7-1)/(0-2) = -8/-2 = 4
Slope int form: y = mx + b
Y = 4x + b
Plug in a point
1 = 4(2) + b, b = -7
Equation: y = 4x - 7
