Slove 4x - c = k for x

Step-by-step explanation:

The given equations are

x2+y3=xy9

⟹xy2y+3x=xy9

⟹3x+2y=9 ........(i) 

x4+y9=xy21

⟹xy4y+9x=xy21

⟹9x+4y=21   ........(ii)  

Now (i)×3⟶9x+6y=27   .....(iii)

Subtracting (iii) from (ii),

−2y=−6⇒y=3.

Putting y=3 in (i),

3x+2×3=9⟹x=1.∴(x,y)=(1,3)

Answer:

Answer:

width is 7, length is 14

Step-by-step explanation:

x(x+7) = 98

x^2 + 7x = 98

x^2 + 7x - 98 = 0

( x   +   14 )( x  -   7 ) = 0

x+14=0 results in negative measures

x-7=0 ---> x= 7

width is 7, length is 14

Answer:

tan^2 60 - sin^2 45

= (√3)^2- (1/√2)^2

= 3-1/2

= 6-1/2

= 5/2

Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation:

The exact value of tan(60) is sqrt(3), and sin(45) is 1/sqrt(2)

tan^2 (60) - sin^2 (45)

[tex]=(\sqrt{3})^2-(\frac{1}{\sqrt{2}} )^2\\=3-\frac{1}{2}\\ = \frac{5}{2}[/tex]

Answer:

The function has a negative leading coefficient and a maximum vertex point

Explanation:

This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.

This function's end behavior is Down and Down, so it must have a negative leading coefficient.

The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.

This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.

This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.

Answer:

Leading coefficient: negative

Maximum vertex point

Using probability concepts, it is found that P(X) = 0.68.

The probabilities given are:

Event X is the probability of living in either South America, Asia or Europe, thus it's probability is the sum of these three probabilities, that is:

[tex]P(X) = 0.06 + 0.55 + 0.07 = 0.68[/tex]

Hence, P(X) = 0.68.

Answer:

0.68

explanation:

you're adding the numbers on the graph together

South America = 0.06

Europe = 0.07

Asia = 0.55

0.06 + 0.07 + 0.55 = 0.68

Answer:

  7%

Step-by-step explanation:

The simple interest formula is ...

  I = Prt . . . . where P is the principal, r is the rate, and t is the number of years

Filling in the given values, we can solve for r.

  490 = 1400·r·5

  490/7000 = r = 0.07 = 7%

The interest rate was 7%.

Answer:

6.5

Step-by-step explanation:

Answer:

6.5

Step-by-step explanation:

Using a calculator, if you typed in 52 divided by 8, you'd get 6.5. You could also express 52/8 as a mixed fraction: 6 4/8. If you look at the mixed fraction 6 4/8, you'll see that the numerator is the same as the remainder (4), the denominator is our original divisor (8), and the whole number is our final answer (6).

I don't know what the graph is asking if you want to graph the equation y=2x+6 the two points are (0,6) and (1,8)

To give the patient a dose of 2g medication with a strength of 4g/0.4ml, you should administer 50 ml of the medication.

Given that,

Dose ordered: 2g of medication

Medication strength: 4g/0.4ml

Conversion factor: 10

To calculate the volume of medication you need to give the patient,

Use a simple formula:

Volume (in ml) = (Dose ordered / Strength) x Conversion factor

In this case,

The dose ordered is 2g and the strength is 4g/0.4ml.

To find the conversion factor,

Divide 4g by 0.4ml, which equals 10.

So, using the formula,

The volume of medication you need to give the patient would be:

Volume (in ml) = (2g / 0.4ml) x 10

Now, calculating this:

Volume (in ml) = 5 x 10

Hence, you should give the patient 50ml of medication.

Answer:

50 L of petrol is needed to travel 600 km.

Step-by-step explanation:

The car travels 1 km in 20/240 L of petrol.  

Then,  

Petrol needed to travel 600 km  

20/240 × 600  

20/24 × 60  

20/4 × 10  

5 × 10

= 50 L

Answer:

50 liters

Step-by-step explanation:

Petrol needed to travel 240 Km = 20 liters

Petrol needed to travel 1 Km = 20/240

Petrol needed to travel 600 Km = [tex]\frac{20}{240} * 600[/tex]

      = 50 liters
