12 will fit in the box for number 1
Answer:
-3.0625
Step-by-step explanation:
just plug in -12
3/4t-3
3/2(-12)-13
then solve to get -3.0625 or -3.06
and this is how you solve any problem like this.
Yes, I think the answer is y = 7. The line x = 4 runs vertical (because all of the points in that line have an x-value of 4) so any line that is perpendicular to it has to be horizontal. Any line that is horizontal is in the form y = (some number). In order for the new line to run through the point (5,7) it would have to have the same y-value as that point, which is 7. So the new line is y = 7. Hope this helps :) (P.S. try graphing them both if you need a visual.)
