Answer: A
Step-by-step explanation:
An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.
y = -5x - 4
Test:
-52 = -5(10) - 4
-52 = -54 FALSE
2 and 4/7, 32/14, 9/3.5, Ect.
P+q= 5x^2+2
q-p= -(x-2) (x+2)
Answer:
x= 361
Step-by-step explanation:
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
