Answer:
x = -1/3
Step-by-step explanation:
4(3x-1)+8=2(3x+5)-8
Distribute
12x -4 +8 = 6x +10 -8
Combine like terms
12x +4 = 6x +2
Subtract 6x from each side
12x-6x +4 = 6x-6x +2
6x+4 =2
Subtract 4 from each side
6x+4-4=2-4
6x =-2
Divide each side by 6
6x/6 = -2/6
x = -1/3
Answer:
i'm pretty sure the y-intercept would be 5
Answer: 8
Step-by-step explanation:
Pythagorean theorem - a^2+b^2=c^2
a^2+15^2=17^2
a^2+225=289
(subtract 225 from both sides)
a^2=64
(sq root both sides)
a=8
The median height is the one in the middle when placed in numerical order. Which in this case, it is 73. (the bolded numbers are those that are being crossed out)
72, 72, 73, 75, 78
72, 72, 73, 75, <span>78
</span>72, 72, 73, 75, 78
73 is the median height!
