Answer:

<h2>4x-5y+32=0 is the right answer.</h2>
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
Answer:
x = -2
Step-by-step explanation:
x^a × x^b = x^(a+b)
Similarly,
(5/3)^(-5) × (5/3)^(-11) = (5/3)^(-5-11)
= (5/3)^(-16)
-16 = 8x
x = -2
First add 13.2 to both sides to get 0.5x > 0.1x + 33.2.
Then subtract 0.1x from both sides to get 0.4x > 33.2.
Lastly, divide each side by 0.4 to get a final answer of x > 83.
