Answer:
y=-3x+10
Step-by-step explanation:
You see you can break it up by 30's, 30 is its greatest common factor, so 30 can go into 90 3 times and 120 4 times so it turns to= 3/4
Answer:
c=2
Step-by-step explanation:
translation:
5x2-3x2=c2
10-6=4
4=c2
4/2=c2/2=c=2
1 block = 25' x 25' = 625’
Concert space = 70,000’
1 security guard per block
70,00’/625’ = 112’ = number of security
guards
12000*625 = 7,500,000’
7,500,000’/7000 = 1071.43 or
1070 people can fit into the block
Answer:
Option A. x < -4
Step-by-step explanation:
The given function is f(x) = -(x + 6)(x + 2)
General form of the function will be,
f(x) = -(x² + 2x + 6x + 12)
= -(x² + 8x + 12)
Vertex form of the function will be,
f(x) = -[x² + 2(4)x + 12]
= -[(x² + 2(4)x + 16) - 16 + 12]
= -(x + 4)² + 4
Therefore, parabola for the function above will open down with vertex (-4, 4) as shown in the graph attached.
Graph shows the function is increasing in x < -4 and decreasing in x > -4.
Therefore, Option A. is the correct answer.
