Answer:
A) Outside both: 7
Intersection: 6
Only ET: 7
Only NDC: 10
B) 17/30
Step-by-step explanation:
Outside both: 7
Union: 30 - 7 = 23
Intersection: 13 + 16 - 23 = 6
Only ET: 13 - 6 = 7
Only NDC: 16 - 6 = 10
P(only one) = (7+10)/30
17/30
Step-by-step explanation:
y = x² − 14x + 24
To convert to vertex form, complete the square. Take half of the second coefficient, square it, then add the result to both sides.
(-14/2)² = 49
y + 49 = x² − 14x + 49 + 24
y + 49 = (x − 7)² + 24
y = (x − 7)² − 25
The vertex is (7, -25).
C) They satisfy equation A but not equation B
________________
EXPLANATION
4y - 3x = 16
4(0.25) - 3(-5) = 16
1 -3(-5) = 16
1 + 15 = 16
16 = 16
-x - 8y = 3
-5 - 8(0.25) = 3
-5 - 2 = 3
-7 = 3
Doesnt solve equation B
