How do you write 0.25 in scientific notation?

2.5 x 10^-1

Step-by-step explanation:

To put this into scientific notation, move the decimal to when you have a whole number in the one's place:

0.25

2.5

The decimal got moved to the right once so the exponent will be negative:

2.5 x 10^-1

That is your answer

Hope this helps!

2.5 × 10^-1

Step-by-step explanation:

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.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
