Answer:

If f(x)=g(x), the solution is x=-2

Step-by-step explanation:

We are given:

f(x)=3x+3\\g(x)= (-1/2)x-4

We need to find the solution if f(x)=g(x)

Now solving for f(x)=g(x)

f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2

If f(x)=g(x), the solution is x=-2

The points (2,4) and (-2,-4) are plotted on a coordinate plane the equation is y = a * x what is A?
laila [671]

A equals to 2.

<u>Step-by-step explanation:</u>

y = mx + c is the equation of the line and m is the slope and c is the y- intercept.

In the given equation, y = ax , a is the slope.

Slope A can be found by means of the formula, and using the points (2,4) and (-2-4)

slope, A = (y₂ -y₁) /  (x₂-x₁)

Plugin the values as,

A = (-4-4) / (-2-2) =  (-8) / (-4) = 2

So the value of A is 2.
