Find the X-intercept<br> f(x)=3^(x-1)-2
Natasha_Volkova [10]
<h2>Hello!</h2>

The answer is:

The function intercepts de x-axis at "x" equal to 1.631.

<h2>Why?</h2>

To find the x-intercept of the function, we need to make f(x) or "y" equal to 0, and then, isolate "x".

So, isolating we have:

f(x)=3^{(x-1)} -2\\\\0=3^{(x-1)} -2\\\\3^{(x-1)}=2\\\\Log_{3}(3^{(x-1)})=Log_{3}(2)\\\\x-1=0.631\\\\x=0.631+1=1.631

Hence, we have that the function intercepts de x-axis at "x" equal to 1.631.

Have a nice day!

Note: I have attached a picture for better understanding.

Angle 3 and 4 from a Linear pair. The measurement of angle three it’s 4 more than three times the measurement of angle 4
kondor19780726 [428]

Answer:

Step-by-step explanation:

a linear pair of angles will equal 180 degrees.

let angle 3 be x and angle 4 be y

x + y = 180

x = 3y + 4

now we sub

3y + 4 + y = 180

4y + 4 = 180

4y = 180 - 4

4y = 176

y = 176/4

y = 44 <==== angle 4 = 44 degrees

x + y = 180

x + 44 = 180

x = 180 - 44

x = 136 <=== angle 3 = 136 degrees
