Answer:
x = - 8, x = 6
Step-by-step explanation:
Given the 2 equations
x² + y² = 100 → (1)
y = x + 2 → (2)
Substitute y = x + 2 into (1)
x² + (x + 2)² = 100
x² + x² + 4x + 4 = 100
2x² + 4x + 4 = 100 ( subtract 100 from both sides )
2x² + 4x - 96 = 0 ( divide through by 2 )
x² + 2x - 48 = 0 ← in standard form
(x + 8)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 6 = 0 ⇒ x = 6
Alright bud the best answer to this question will be that the mode is 12 because it appears the most

553,000 is the answer for rounding up
Answer:
D
Step-by-step explanation:
you need to first do 5.89- [(5.89 * 15)/100]=5.89-0.8835=5.0065
then 5.0065 * 2 = 10.013 because it is 15% each dozen then
[(10.013 * 5)/100] =0.50065 then 10.013 - 0.50065 = 9.51235
and lastly (9.51235 * 7)/100 = 0.6658645
finally 9.51235 + 0.6658645= 10.1782145
and then you just need to round it to the nearest hundredths and you will get 10.18
