Answer:
3. undefined (vertical line)
4. 1
7. -4
8. 3
11. undefined (vertical line)
12. -1/3
Step-by-step explanation:
You can use the slope formula to calculate the slope which is (y2-y1)/(x2-x1)
3. (-4 - (-2)) / (6-6) denominator is 0 here so the slope is undefined (vertical line)
4. (7 - 1) / (-2 - (-4)) = 6 / 6 = 1
7. (1 - (-7)) / (2 - 4) = 8 / -2 = -4
8. (-1 - 5) / (0 -2 ) = -6 / -2 = 3
11. (3 - 0) / (-6 - (-6)) = 3 / 0 = undefined (vertical line
12. (2 - 3) / (-5 - (-2) = 1 / -3 = -1/3
Answer:
1) Congruent
2) Congruent
3) Not Congruent
4) Congruent
5) Congruent
6) Congruent
Step-by-step explanation:
1) If you laid the triangles in the same direction, they both share the bottom angle and top angle, making it congruent. If you use this same thought process, you can figure out the rest.
Okay so slope intercept form is y=mx+b
Where b is the y intercept, m is the slope and x is the changing variable. So in this case let x represent the number of hours and m equal the cost per hour $2. That leaves $5 as the y intercept. So your equation is y=2x+5
Answer:
|3+x|=-3
Step-by-step explanation:
This equation has no solution because the answer would be - x=-3 X can't be negative 3 because if we inputed -3 into the absolute value, it wouldn't make any sense, as the absolute value of -3 is +3
