Y= 3X + 1. Perpendicular means you would change the slope by flipping it and changing the sign. So the slope then becomes 3. Then you use your points to find the y-intercept by filling in the variables. 7=3(2) + B. 7=6 + B. Then subtract 6 from both sides. B=1. Then you just put your problem back into slope intercept form with your new slope and y-intercept. Y=3x + 1.

Scientific Notation:<br> what’s (2.2 x 10 to the -4) - (3 x 10 to the 2)
Marrrta [24]

Answer:

2.23\times10^4

Step-by-step explanation:

In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

(2.2\times10^{-4})-(3\times10^2)

Turn the notations into standard form:

2.2\times10^{-4} = .00022

3\times10^2=300

.00022-300=22300

=22300

Turn into notation form:

22300 = 2.23\times10^{4}

Hope this helps.
