Answer:
x=4
Step-by-step explanation:
hope it will help
First no.=x
2nd no.=2x
3rd no. =2x+6
x+2x+2x+6=26
5x+6=26
5×=26-6
5x =20.......divide both sides by 5
x=4
1st no.=x=4
Answer:
=7
Step-by-step explanation:
Answer:

Step-by-step explanation:
All the absolute value functions given in the option are of the form:
, where (h,k) is the vertex
From your description the absolute value graph has vertex at (-4,-2)
Hence h=-4 and k=-2.
We substitute to get:

We simplify to get:

Answer:
g(x) = Negative two-fifths(10)x
Step-by-step explanation:
In order to reflect a function over the x-axis, you have to multiply the function by minus one.
Given the function:
f(x) = 2/5(10)^x
Its reflection over the x-axis is:
-f(x) = -2/5(10)^x = g(x)
