Answer:
(0,4) and (-2,0)
Step-by-step explanation:
y=3x²+4x+4
y = -2x +4
3x²+4x+4 = - 2x +4
3x²+6x=0
3x(x+2)=0
x=0, x= -2
x=0, y=-2x+4= -2*0 + 4 =4, (0,4)
x= - 2, y = 2x + 4= 2*(-2) +4=0, (-2,0)
Given:
420 tropical fishes
angel fish = x
parrot fish = 6x
x + y = 420
y = 6x Choice D.
x + y = 420
y = 6x
x + 6x = 420
7x = 420
x = 420 / 7
x = 60 number of angelfish
y = 6x
y = 6(60)
y = 360 number of parrot fish

Answer:
=c+114
Step-by-step explanation:
Answer:
Mean is 17
Median is 10.5
Mode is 2
Range is 37
Step-by-step explanation:
<u>Mean is the average: 2 + 2 + 6 + 15 + 38 + 39 = 102 / 6 = 17 MEAN</u>
<u />
<u>Median is the middle: 2, 2, 6, 15, 38, 39</u>
Between 6 and 15 -> 15 - 6 = 9 / 2 = 4.5
6 + 4.5 = 10.5
Median is 10.5
<u>Mode is most common: </u><u>2, 2</u><u>, 6, 15, 38, 39</u>
<u />
Mode is 2
<u>Range is the difference between the highest and the lowest number: 39 - 2</u>
37
Range is 37
