Answer:
-4
Step-by-step explanation:
From the qquadratic formula
x1 = [ -b +√(b² - 4ac) ] / 2a
x2 = [ -b -√(b² - 4ac) ] / 2a
When added together the ± square root cancels out leaving
(-b/2a) + (-b/2a) = -b/a
For 2x² + 8x -3 = 0
-b/a = -8/2
-b/a = -4
Answer:Pretty sure it’s c
Step-by-step explanation:
The equation which relates the height of the flower pot based on the <em>number of pots</em> is 4a + 16
<u>Creating a system of linear equations based on the information given</u> :
- a = number of flower pots
4a + b = 32 - - - - - (1)
2a + b = 24 - - - - - (2)
From (2)
2a + b = 24
Make b the subject ;
b = 24 - 2a - - - - (3)
Put b = 24 - 2a in (1)
4a + 24 - 2a = 32
4a - 2a + 24 = 32
2a = 32 - 24
2a = 8
a = 8/2
a = 4
From (3) :
b = 24 - 2(4)
b = 24 - 8
b = 16
The equation which relates the height of a flower pot is 4a + 16

9 Ibs(pounds) + 6 oz(ounces) ⇒ ounces
First, let's find out how many 1 pound is equal to in ounces.
Since 1 pound is equal to 16 ounces, multiply the 9 pounds by 16.
Now, add the remaining 6 ounces to 144 ounces, which is also 9 pounds.
The answer is 150 ounces.
Hope this helps!☺
