Answer:
y2- y1 over
x2 -x2


Step-by-step explanation:
slope is m =

use the -3 for b and you get

slope intercept form
So in order to find line AC you must find line AD and DC then plus them together.
to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74
Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6
now plus AD and DC which should give u 11.3
80 because if you divide 24 by 3 and multiply it by 2, you get the second value (16), then divide 24 by 3 and multiply it by five, you get the third value (40). Then you add all three values (24,16,40) and you get 80
I have no idea what to do in problem 1
but I will do problem 2
A. 2⁵ = 32 (2×2×2×2×2=32)
B. 4³/2 = 32 (4×4×4=64 and then 64÷2=32
the others are not equal to 32
