It's $g(x)=f(-x)=f(x)$ .

Reflection over y-axis is the same as original function.

Hope this helps.

2 times x plus x plus 45 =180

NARA [144]

Answer:

x= 45

Step-by-step explanation:

2x+x + 45 = 180

Combine like terms

3x+45 =180

subtract 45 from each side

3x+45-45= 180-45

3x = 135

Divide each side by 3

3x/3 = 135/3

x = 45

t/5 = 2.9
For the first step, I would multiply both sides by 5, to get rid of the fraction.

That will leave
t = 14.5

So with what you have on your screen, I would drag “x” and “5” to both sides of the equation.
