Answer:
The answer to your question is:
Step-by-step explanation:
a. 4.25 x 10⁶ = 4 250 000 False
b. 6.38 x 10⁹ = 63 800 000 False
c. 5.11 x 10⁻² = 0.0511 False
d) 2.79 x 10⁻⁴ = 0.000279 True
A-False
B-False
C-False
D-True
Answer: no solution
20x - 36 = 20x - 45
-20x. -20x
-36 = -45 since this is not true, the answer is there is no solution
Answer: 129
It is 129 because y is less than 70 so the greatest possible value for that is 69 and z is less than or equal to 60 so 69 + 60 =129
min{5 x^2 - 20 x + 3} = -17 at x = 2
