<span>You simply set them to equal each other and solve!
y=2x+5
y=4x-2
Due to logical assumptions, we can say that 2x+5=4x-8
+8
2x+13=4x
-2x 13=2x
 /2 x=13/2,, or 6.5</span>

First of all, you need to simplify the expressions in order to know whether they are equal. Then, it all depends on the expression, after you simplify an expression, it will seem much easier to determine that.  <span />

A sequence is defined by the formula f(n + 1) = f(n) – 3. If f(4) = 22, what is f(1)?
julsineya [31]

f(n) = f(n+1) +3

f(1) = f(2) +3

f(2) =f(3) +3

f(3) = f(4) +3

So f(1) = f(n) + 3* (n-1)

Put n=4 here so you found

f(1) = f(4) + 3* 3

= 22 +9

=31 ans

The advantage of the graphing calculator is that you just have to find two independent equations, introduce them in the calculator and it will find the intersection point ot the two graphs.

The equations that you have to introduce are:

1) y = 2.25x + 24

2) y = 2.75x + 23

The algebraic solution, which will give you the same coordinates of the intersection point of the graphs is

2.25x + 24 = 2.75x + 23

2.75x - 2.25x = 24 - 23

0.5x = 1 => x 1 /0.5 = 2.
