X+2y=18
-x -x
2y=-x+18
/2 /2 /2

y=mx+b
y=-1/2x+9

the slope is -1/2

You solve for y. you dont need the x intercept
x+2y=18
2y=-x+18
divide everything by two
y=-1/2x+9
the slope would be -1/2
since in the equation y=mx+b
m represents the slope which in this case would be -1/2

Jill and Erika made 5 gallons of lemonade for their lemonade stand. How many quarts did they make? If they charge $2.50 per quar

yawa3891 [41]

a. How many quarts did they make is 25 quarts of lemonade

b. How much money will they make if they sell it all is $62.50

a. Calculation to determine How many quarts did they make.

Given: 1 gallon =5 quarts

Hence:

5 gallons of lemonade=5×5 quarts of lemonade

5 gallons of lemonade=25 quarts of lemonade

b. Calculation to determine how much money will they make if they sell it all

Given: 1 quarts=$2.50

Hence:

25 quarts=25 ×$2.50

25 quarts=$62.50

Inconclusion:

a. How many quarts did they make is 25 quarts of lemonade

b. How much money will they make if they sell it all is $62.50

A product is made up of components A, B, C, D, E, F, G, H, I, and J. Components A, B, C, and F have a 1/10,000 chance of failure

lesantik [10]

Answer:

The overall reliability is 99.7402 %

Step-by-step explanation:

The overall reliability of the product is calculated as the product of the working probability of the components.

For components A,B,C and F we have :

$P(failure)=\frac{1}{10000}$

⇒

$P(Work)=1-\frac{1}{10000}=\frac{9999}{10000}=0.9999$

For components D,E,G and H we have :

$P(failure)=\frac{3}{10000}$

⇒

$P(Work)=1-\frac{3}{10000}=\frac{9997}{10000}=0.9997$

Finally, for components I and J :

$P(failure)=\frac{5}{10000}$

⇒

$P(Work)=1-\frac{5}{10000}=\frac{9995}{10000}=0.9995$

Now we multiply all the working probabilities. We mustn't forget that we have got ten components in this case :

Components A,B,C and F with a working probability of 0.9999

Components D,E,G and H with a working probability of 0.9997

Components I and J with a working probability of 0.9995

Overall reliability = $(0.9999)^{4}(0.9997)^{4}(0.9995)^{2}=0.997402$

0.997402 = 99.7402 %

4(x−5) <br> 2<br> =36<br><br> can i please get an answer to this

Nutka1998 [239]

Answer:

19/2 or 9.5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(x−5)(2)=36

8x+−40=36(Distribute)

8x−40=36

Step 2: Add 40 to both sides.

8x−40+40=36+40

8x=76

Step 3: Divide both sides by 8.

8x/8=76/8

x=19/2

Help me, please!! Estoy desesperada y no hablo inglês!! Help

$D:x>0\\
\log x+\log x^2+\log x^3=-6\\
\log (x\cdot x^2\cdot x^3)=\log 10^{-6}\\
x^6=10^{-6}\\
x^6=\left(\frac{1}{10}\right)^6\\ \boxed{x=\frac{1}{10}}$
