Answer:

points (2,2) and (-2,-4):

y-intercept= -1, the equation is y= 3/2x -1

points (-2,0) and (0,-5):

y-intercept = -5, the equation is y= -5/2- 5

points (0,3) and (i can’t read the other one)

y-intercept= 3, the equation is y=4x+ 3!

What is the median and mode

viktelen [127]

Median is the middle number

60, 60, 65, 70, 70, 85, 90

70 is your median

mode is the number(s) that show up the most
60 and 70 is your mode, since they show up twice (one more than the others)

Range is largest number minus the smallest
90 - 60 = 30, 30 is your range

Mean is all the numbers added together divided by the number of numbers there are
60 + 90 + 65 + 70 + 70 + 85 + 60 = 500
500/7 = 71.42
Mean = 71.42

hope this helps

Evaluate the polynomial 6x - y for x= -3 and Y=2. A.15 B. -20 C.4 D.-16

ra1l [238]

I think the answer is B.
6(-3)=-18, and y=2
so 6x-y=-18-2=-20

$\displaystyle\\Answer:\ x=\sqrt{2}\ \ \ \ \ x=-\sqrt{2}\ \ \ \ \ x=\frac{ln5}{2}$

Step-by-step explanation:

$5x^2-x^2e^{2x}+2e^{2x}=10$

$Let:\ x^2=t \ \ \ \ \ e^{2x}=v\\Hence,\\5t-tv+2v^2=10\\5t-tv+2v^2-10=10-10\\5t-tv-10+2v^2=0\\t(5-v)-2(5-v)=0\\(5-v)(t-2)=0\\5-v=0\\5-v+v=0+v\\5=v\\5=e^{2x}$
