2x²-10xy+3xy-15y²

Add like terms.

2x²+ (-10xy+3xy) -15y²

Simplify.

2x² + (-7xy) - 15y²

Rearrange the equation.

2x²-15y²-7xy

There are four terms in your algebraic expression.  Notice that the left two terms have the factors 2 and x in common, whereas the right two terms have the factors 3 and y in common:

2x(x-5y) + 3y(x-5y).  Can you now factor this further?  Note that the two terms here have a common factor, (x-5y).

Graph the equations to find the solution(s) to the system.
liraira [26]

By graphing both equations, we see that the solutions of the system of equations are  (1.05, 4.05) and  (-4.97, - 1.97)

<h3>How to solve the system of equations?</h3>

Here we have the system of equations:

y = x + 3

y = 13*(x + 5)*(x - 1).

To solve this system graphically, we need to graph both equations and see where the curves intercept.

The graph of the two equations can be seen below.

There are two solutions, one is (1.05, 4.05) and the other is (-4.97, - 1.97)

yawa3891 [41]

An equation is formed of two equal expressions. The equation of function g(x) in terms of f(x) is g(x) = -3[f(x)].

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given graph is the graph of an exponential function, the general equation of an exponential function is given by the y=aeᵇˣ. To get the function f(x) and g(x), you need to substitute the points in the given function and produce the equation of each function.

The equation for f(x) from the given graph can be written as,

f(x)=e^{(\ln2)x}-2

Now, similarly from the graph the function of g(x) can be written as,

g(x)=-3e^{(\ln2)x}+6

Further, the equation of function g(x) in terms of f(x) can be written as,

g(x) = -3[f(x)]
