Answer:

Yes

Step-by-step explanation:

If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:

ECM = 3x + 15

becomes

90 = 3x + 15

75 = 3x

25 = x

ACE = 4x - 10

becomes

90 = 4x - 10

100 = 4x

25 = x

Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees

laiz [17]

Answer:

The answer is D

Step-by-step explanation:

$when \: fx = |7x + 1| - 8 \\ while \: y \\ gx = - 2 \\ therefore \: find(fx - gx) \\ (|7x - 1| - 8) - ( - 2) \\ |7x - 1| - 8 + 2 \\ |7x - 1| - 6$

Kim rolls a dice and flips a coin

tankabanditka [31]

Answer:

part a

The probability of getting a 2 is 1/6 and the probability of getting a head is 1/2. The probability of getting both is thus 1/6 x 1/2= 1/12

part b

The probability of getting an even number is 3/6 = 1/2. The probability of getting a tail is 1/2. The probability of getting both is thus 1/2 x 1/2= 1/4.

Which two points are on the graph of y = -x + 3?

ch4aika [34]

The points (0, 3) and (4, -1) are on the graph of y = -x + 3.

I have a site that I use a lot that is perfect for problems like these. It's called Desmos.com. It's basically a free online graphing calculator that is super helpful for most problems relating to graphs.
