The vertex of <span>y = 7x2 + 14x + 4</span> is at
(-1,-3) (see attachment)
No that’s equivalent to 7 + 7x
N= x+15 where n = nina, x = the amount hiked together and the 15 is how much she already walked.
Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)
5x4 = 20
10x3 = 30
20 + 30 = 50 points
