How do you round decimals like 0. Something to 1 significant figure

Step-by-step explanation:

1.look at the first non-zero digit if rounding to one significant figure.

2.look at the digit after the first non-zero digit if rounding to two significant figures.

3.draw a vertical line after the place value digit that is required.

4.look at the next digit

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
