Answer:

x-7*5

Step-by-step explanation:

The difference is subtraction and the question asks the difference of 7 and a number we can call that number x. So x minus 7 multiplied by 5, or in other words x minus 7 times 5.

Hope that helps, and good luck!

Step-by-step explanation:

You can do this two ways, the easiest way is to look at the graph.

What is g(4) means: When the x value equals 4, what does y equal?

Look for the coordinate with the x-value of 4 (it's asking for g(4). Now if you look at the y-value of the coordinate, it should tell you what g(4) is. So since the coordinate is (4,-1), g(4) is -1.

Another way to do it is to plug in 4 for x in the equation. So...

g(4) = -[f(4) - 3)]

g(4) = -[4 - 3]

g(4) = -[1]

g(4) = -1

How many solutions does the system of equations below have?<br><br> y= 3x + 4<br> 2y -8 = 6x

Cerrena [4.2K]

Answer:

infinitely many solutions (infinite solutions)

Step-by-step explanation:

2y - 8 = 6x

+8 +8

-------------------------------

2y = 6x + 8

$\frac{2y}{2}$ = $\frac{6x}{2}$ + $\frac{8}{2}$

-------------------------------

y = 3x + 4

Because 3x + 4 = 3x + 4, there are infinitely many solutions to this system of equations. This is because they're the exact same equations. Any substitution for x will give you a true statement to y when compared to the other equation.
