This one was pretty tough but Math way helped, you should try it out, it explains the problems so you can learn it. I got x = 0, 5

What you want to do is write the numbers with similar bases, and then you can cross the bases off. Like this:

25^x+2=125^3x+4
5^2(x+2)=5^3(3x+4)
Now you can cross the similar bases off.
2(x+2)=3(3x+4)
2x+4=9x+12
7x=-8
X=-8/7

How do you determine whether a system of linear equations has no solutions, one solution, or infinitely many solutions?

Charra [1.4K]

The answer to this is

<span> If the lines are the same, the equations are dependent linear equations. Using the graph of y = x and x + 2y = 6, shown below, determine how many solutions the system has. Then classify the system as consistent or inconsistent and the equations as dependent or independent. The lines intersect at one point.</span>

Hope This Helps!

What characteristics best describe the graph? Choose all that apply. *

marin [14]

Answer:

Options (1), (3) and (7)

Step-by-step explanation:

Characteristics of the given graph are as followed.

1). For every input value (x-value) there is a different output values (y-values).

So the points on the graph represent a function.

2). Coordinates of all the points are distinct and separate (not in fractions or decimals).

Function given is a discrete function.

3). For every increase in the x-values of the points there is a decrease in y-values.

Therefore, given function is a decreasing function.

Therefore, Options (1), (3) and (7) are the correct options.
