Which graph correctly solves the system of equations below?

y = −x^2 + 3x + 1

y = x^2 + x + 1

A) two quadratic graphs opening up. They intersect at negative 3, 4.

B) quadratic graph opening up and quadratic graph opening down. They intersect at 1, 3 and 0, 1.

C) two quadratic graphs opening down. They intersect at 0, 3.

D) quadratic graph opening up and quadratic graph opening down. They intersect at 1, 4 and 0, 3.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
