Answer: Bigger

Step-by-step explanation: If you put -1/4 in decimal form you get -.25. If these numbers were positive, 1.4 would obviously be bigger than .25, but since these numbers are negative, -.25 would be bigger than -1.4.

Slope = 3: (6, 14) Write the equation in y=mx+b form

andrew-mc [135]

Step-by-step explanation:

Equation of line in slope point form is given as:

$y - y_1 = m(x - x_1)\\\therefore \:y - 14 = 3(x - 6) \\ \therefore \: y - 14 = 3x - 18 \\ \therefore \: y = 3x - 18 + 14 \\ \therefore \: y = 3x - 4 \\ \implies \: y = mx + b$

If P and Q are two sets then n( P-Q) means ?

Lapatulllka [165]

$\huge{\mathbb{ \tt{ANSWER}}}$

I shall use the symbol U for union

^ for intersection

~ for complement

The property of set subtraction states that for any sets X and Y, X-Y = X ^ Y~

That is in words, X throw away Y is the same as the intersection of X and the complement of Y

or X and anything NOT in Y

At the SET level, the proof looks like this:

(P-Q) U (Q-P) = « given

(P^Q~) U (Q ^ P~) = « property of set subtraction

(P U Q) ^ (P U P~) ^ (Q~ U Q) ^ (Q~ U P~) = « distributive property

(P u Q) ^ (Q~ U P~) = « Union of any set with it's complement is the universal

set which gets dropped by any intersection of a non-universal set

(P u Q ) ^ (Q ^ P)~ = « De Morgan's Law

(P u Q) - (Q ^ P) = « property of set subtraction

(P u Q) - (P ^ Q) « commutative property

At the ELEMENT level, the proof looks like this:

» Proves left side is subset of right side

If x is in (P-Q) U (Q-P) then x is in (P-Q) OR x is in (Q-P)

If x is in P-Q then x is in P but not in Q.

Then X is in P U Q.

Since x is not in Q, x is NOT in P ^ Q

Hence x is in P U Q but NOT in P^Q, which

means it is an element if (P U Q) - (P ^ Q)

Therefore x is an element of the set defined by the right side, which means (P-Q) U (Q-P) is a subset of (P U Q) - (P ^ Q)

« proves right side is subset of the left side

If x is an element of (P U Q) - (P ^ Q) then

x is in (P U Q) but NOT in (P^Q)

Since x is in P U Q, x is in P OR x is in Q.

Since x is NOT in (P^Q) then x is NOT in BOTH P and Q.

Hence x is in either P or Q but not both.

If x is in P, then x is not in Q, so x is in P-Q.

Therefore x is in (P-Q) U (Q-P).if x is in Q, then x is not in P, so x is in Q-P.Therefore x is in (Q-P) U (P-Q).There x is an element of set defined by the left side, which menas (P u Q)-(P ^Q) is a subset of (P-Q) U (Q-P).

Drag the correct steps into order to solve the equation 6x+6= -12 for x

damaskus [11]

Answer:

x = -3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 6 from both sides:

6x + 6 (-6) = -12 (-6)

6x = -12 - 6

6x = -18

Isolate the variable, x. Divide 6 from both sides:

(6x)/6 = (-18)/6

x = (-18)/6

x = -3

x = -3 is your answer.

What is the concentration after 11 minutes? Ground to 3 decimal places.

sergiy2304 [10]

In order to find the concentration after 11 minutes, let's use the value of t = 11 in the function C(t) and then calculate its value:

$\begin{gathered} C(t)=0.04(1-e^{-0.2t}) \\ C(11)=0.04(1-e^{-2.2}_{}) \\ C(11)=0.04(1-0.1108) \\ C(11)=0.04\cdot0.8892 \\ C(11)=0.035568 \end{gathered}$

Rounding to three decimal places, we have a concentration of 0.036.
