Step-by-step explanation:
so therefore mark jogged 2 36/70km more than his sister
Answer:
see below
Step-by-step explanation:
Corresponding letters (vertices) are in the same order in the similarity statement. That is, if L is the first letter in ∆LMN, then it corresponds to the first letter (R) in ∆RST. That is the meaning of ∆LMN ~ ∆RST.
3. Everywhere you see L, replace it with R.
Everywhere you see M, replace it with S.
Everywhere you see N, replace it with T.
This goes for both segments and angles.

4. Everywhere you see A, replace it with H.
Everywhere you see B, replace it with G.
Everywhere you see C, replace it with F.
Everywhere you see D, replace it with E.
This goes for both segments and angles.
(-1,1)
D0 means starting at the origin of Z in this case, so doing the same thing as always, multiply the scale factor -1/2 to the coordinate of Z giving you (-1,1) and this is the final answer because the origin is (0,0) so doesn’t change anything
Answer:
Yes
Step-by-step explanation:
You can set up your proportion as
*
you then multiply across to get
. Since this number is less than 1, it's definitely less than 3.
Rewrite the equation:
-2x^2 - 3x + 8 = 0
2x^2 + 3x -8 =0
Where a=2, b=3 and c=-8
Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73
A positive discriminant implies that the equation has two different real solutions.
Answer: the discriminant is 73, so the equation has 2 real solution
