Can someone help me with 14 and a few others I need help ):
Gelneren [198K]

Answer:

26, -0.85, 17

Step-by-step explanation:

hi! so for 14, you can plug in -11 for every x in the equation.

f(-11)= 15-(-11)

=15+11

=26

your answer is 26.

for 15, we can plug in 0.3 for x.

g(0.3)=-2.5(0.3)-0.1

= -0.75-0.1

= -0.85

your answer is -0.85.

for 16, you can plug in -17 for x.

f(-17)= -(-17)

=17

your answer is 17.

Masteriza [31]

Answer:

They're all the same distance from 0 on the number line.

Step-by-step explanation:

That's a similarity. If you want to know the difference, then it should be that one is greater than 0, and the other is less than 0.

I'm pretty sure that's what you're asking for, right?
