Answer: 
Step-by-step explanation:
1. By definition, scientific notation has the following form:
Where:
<em> a</em> is a number between 1 and 10 but does not include 10.
<em> b </em>an integer.
2. When you multiply 3.25 by 7.8 the result is 25.35 and when you multiply 
by 
, you obtain 
, but to write ree thsult in scientific notation, the decimal point must be after the first digit. Therefore, you must move the decimal point one place to the left. So, the exponent changes from 9 to 10:
The formula for point-slope form is y-a=m(x-c), where y and x are variables, a is simply one point in y, m is the slope, and c is simply one point in x. The first thing we can find is m, or the slope. This is found by dividing the change in y over the change in x. The equation for this is (I’ll plug the points in the equation)
Therefore, our answer is the bottom one as our slope is 1/4.

Y=|x|-2
this can be easily seen by testing f(0) for all functions:
f1(0)=|0-2|=2
f2(0)=|x+2|=2
f3(0)=|x|-2=-2
f4(0)=|x|+2=2
f(0)=|x|=0, because you want to translate it 2 units down -2 is the expected value
Answer:
-3/4
Step-by-step explanation:
x - 1 = 5x + 2
or, 5x + 2 = x - 1
or, 5x - x = - 1 - 2
or, 4x = - 3
or, x = - 3 / 4
