4. When finding the intersection of two lines from both Algebra I and Geometry, you first "set the linear

Masteriza [31]

Answer:

The intersection point is (-4,-19)

Explanation:

The two given equations are:

y = 5x + 1

y = 2x - 11

To find the intersection point, we will start by equating the two given equations and solving for x

This is done as follows:

5x + 1 = 2x - 11

5x - 2x = -11 - 1

3x = - 12

x = -4

Then, we will use the x and substitute in any of the equations to get the value of y

Using the first equation:

y = 5x + 1 = 5(-4) + 1 = -19

Check using the second equation:

y = 2x - 11 = 2(-4) - 11 = -19 ................? checked

Therefore:

The intersection point between the two given equations is (-4,-19)

Hope this helps :)

Step-by-step explanation:

Step 1: Define

$\displaystyle 2^{x+4} - 12 = 20$

Step 2: Solve for x

Isolate x term: $\displaystyle 2^{x+4} = 32$
Rewrite 32: $\displaystyle log_2(32) = 5$
Rewrite equation: $\displaystyle 2^{x+4} = 2^5$
Set equal: $\displaystyle x + 4 = 5$
Isolate x: $\displaystyle x = 1$
