Answer:

x=-2±√14/1 is the answer

Step-by-step explanation:

2x²+12x+11=0

by using quadratic formula

x=(-b±√b²-4ac)/2a

here a=2,b=12,c=11

x={(-12)±√(12)²-4(2)(11)}/2

x=(-12±√144-88)/2

x=-12±√56/2

x=-6±2√14/2

x=-4±√14/2

x=-2±√14/1

i hope this will help you :)

5/6 = 0.83333... (Repeating)

2/11 = 0.181818... (Repeating)

17/20 = 0.85 (Terminating)

For the number system diagram, from smallest box to larges, it would be natural numbers, whole numbers, and integers, rational numbers, then real numbers. And irrational numbers off to the side, but considering you only have 3 boxes then put the first 3 I mentioned.

It is definetly possible for a number to be both whole and an integer. As long as it's not a fraction, decimal, or negative value.

Y varies jointly with x. Y=16 when x=4 and z=1/2. Find y when x=2 and z=1/4. Enter the value of y in the box. Picture attached,
bogdanovich [222]

Answer:

y = 4

Step-by-step explanation:

Given that y varies jointly with x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = 16 when x = 4 and z = \frac{1}{2} , that is

16 = k × 4 × \frac{1}{2} = 2k ( divide both sides by 2 )

8 = k

y = 8xz ← equation of variation

When x = 2 and z = \frac{1}{4} , then

y = 8 × 2 × \frac{1}{4} = 16 × \frac{1}{4} = 4
