Answer:
4
Step-by-step explanation:
Hi there!
Any point that looks like (a,0), with a y-coordinate of 0 gives us the x-intercept. The x-intercept is <em>a</em>, the x-coordinate.
Given that the line crosses the x-axis at (4,0), the x-intercept is therefore 4.
I hope this helps!

I will answer second attachment and after since I can't see the firs attachment
2nd attachment
if x is negative, then the first number gets infinitely small
look at the second number, the first 2 is -2 which is wrong since it should be +2
3rd option is not because if x=-2, then y=1
answer is D
3rd attachment
2nd: f(x)=60*1.15^x
3rd: no xint
6th: after 7.86 years value tripples
7th maybe: after 8 years value is 183.51, not exatly 184.00
4th attachment
nth score is
f(n)=57+4(n-1)
9th is
f(9)=57+4(9-1)
57+32=89
answer is C 89
5th
f(t)=23000(1.02)^t
t=time in years from 23000
Answer: angle 1 is 150°
Explanation: 150+30=180
