Domain is all the possible inputs of an equation. In this example, the only concern is the x + 5 because the denominator cannot equal 0 because we can't divided by 0. So we set x + 5 equal to zero and solve for x.
x + 5 = 0
x = -5
The restriction is that x cannot equal -5.
Answer:
60
Step-by-step explanation:
you know that if one line is perpendicular to another line, and another line is perpendicular to that line, they are all perpendicular (90). so, all corners are right angles. that means that angle AGD is 90. so, if you know 30, then subtract 30 from 90 and you get that angle AGF is 60. then, because angle AGF and angle EGB are vertical angles, they are congruent, so x is 60.
It should be 100 because it has to add up to 180 and 50+30=80 so the third angle must be 100
Answer:
B, C, D, & E
Step-by-step explanation:
All lines intersect the x axis and y axis so we know B and D are correct. All graphs are in the xy plane unless i () is involved, or C. It crosses the center (origin) of the entire plane so it crosses the origin, or E.
2 2/3 Divided by 4 would be 2/3 because 2 2/3 equals 8/3 and 2 goes into 8 4 times.
