What segment is congruent to AC?<br> A. BD<br> B. BE<br> C. CE<br> D. none
Phoenix [80]
You can find the segment congruent to AC by finding another segment with the same length. So first, you need to find the length of AC.

   C - A = AC
0 - (-6) = AC   Cancel out the double negative
  0 + 6 = AC
        6 = AC

Now, find another segment that also has a length of 6.

   D - B = BD
2 - (-2) = BD   Cancel out the double negative
  2 + 2 = BD
        4 = BD
        4 ≠ 6

   E - B = BE
4 - (-2) = BE   Cancel out the double negative
  4 + 2 = BE 
        6 = BE
        6 = 6

So, the segment congruent to AC is B. BE .

Help please will give brainiest!<br> Write the equation of the line in Slope-Intercept form.
Illusion [34]

Answer:

Y=-2/3+4

Step-by-step explanation:

The slope of the equation can be solved with

2-4/3-0 y2-y1 divide by x2-x1 which gives 3/2 and the y intercept the point at which the slope hits the y intercept which is 4. Also the slope is negative as it’s pointed downwards.

Please help :( I will give u points
gayaneshka [121]

when there is no number with redical sign here it is equivalent to the exponent " 1/2 "

but when it is 3 under redical x that means it is x^1/3

In first one 8 ^(9/2) is same as ( redical 8 ) ^9

In part B it is (3 under redical 125)^9 = ( 125 )^ 9/3 so this also same thing

In part C it is ( 12)^2/7) but the ( redical 12 ) ^7 is equal to ( 12)^7/2 so these two are not equivalent

in part D it is 4^1/5 but ( redical 4) ^5 = 4^( 5/2 which is also not equivalent

Answer : only A and B are equivalent
