P = -23 + 0.13y
For y = 350:
p = -23 + 0.13(350) = -23 + 45.5 = 22.5
For y = 400:
p = -23 + 0.13(400) = -23 + 52 = 29
For y = 450:
p = -23 + 0.13(450) = -23 + 58.5 = 35.5
33,52 Thats what i think at least
Answer:
28
Step-by-step explanation:
The ratio of the triangles is 12:15 which is equal to 4:5
Then you can use that ratio to find the ?
35 would be the 5 so 4 would be multiplyed by 7
Which is equal to 28

Answer:
1) -5 and +5; 2) -9 and +9
Step-by-step explanation:
1) a² + 2ab + b² = 25
(a + b)² = 25 Wrote the left-hand side as a square
a + b = ±5 Took the square root of each side
All values of a + b are -5 and +5.
2) a² − 8ab + 16b² = 81
(a - 4b)² = 81 Wrote the left-hand side as a square
a - 4b = ±9 Took the square root of each side
All values of a - 4b are -9 and +9.
