Answer:

[tex]\huge{\fbox{\sf{ x = -50}}}[/tex]

Step-by-step explanation:

[tex]\frac{x}{5} + 7 = -3[/tex]

Take the L.C.M of 5 and 1 ( i.e 5 )

⇒[tex]\frac{x+7 * 5}{5} = -3[/tex]

⇒[tex]\frac{x+35}{5} = -3[/tex]

Do cross multiplication

⇒[tex]x + 35 = -3 * 5[/tex]

⇒[tex]x + 35 = -15[/tex]

Move 35 to right hand side and change its sign

⇒[tex]x = -15 - 35[/tex]

Remember : The negative integers are always added but posses the negative ( - ) sign.

⇒[tex]x = -50[/tex]

The value of x is [tex]\boxed{\sf{ -50}}[/tex]

Hope I helped!

Here's a linear equation in variable x and we have to compute the value of x for the above equation.

Given equation:

So, Let's start solving the above equation:

Move 7 to the Right hand side,

Remember: Inverse of addition is subtraction

[tex] \sf{ \dfrac{x}{5} = - 3 - 7}[/tex]

[tex] \sf{ \dfrac{x}{5} = - 10}[/tex]

Now multiplying 5 in other side because again the inverse of division is multiplication,

[tex] \sf{ x = - 10 \times 5}[/tex]

[tex] \sf{x = \boxed{ \red{ - 50}}}[/tex]

And the required value for x is -50. So, we are done....

Answer:

0.5289 to the nearest thousandth is 0.529.

Step-by-step explanation: If a number is less than 5, round down, but if a number is 5 or more, round up. The digit after the thousandths place is the digit we should look at to answer the question and it is 9, so we round up from 0.528 or 0.529. So, the answer is 0.529.

Step-by-step explanation:

Well you first have to find the slope, which is y2-y1/x2-x1

Which is -12-7/5-5 and that equals to undefined.

So since you can't find the slope the answer should be undefined.

Step-by-step explanation:

Answer:

√3.14,-√3.14

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

Q1 = 14 − P1 − 0.5P2

Q2 = 19 − 0.5P1 − P2

Recall that:

Profit = Total revenue - Total cost

π₁ = P₁Q₁ MCQ₁

π₁ = P₁(14 - P₁ - 0.5P₂) - Q₁

π₁ = 14P₁- P₁² - 0.5 P₁P₂ - 14 + P₁ + 0.5P₂

π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14

π₂ = P₂ (19 - 0.5P₁ - P₂) - 2(19 - 0.5P₁ - P₂)

π₂ = 19P₁ - 0.5P₁P₂ - P₂² - 38 + P₁ + 2P₂

π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38

The profit functions are π₁  & π₂

The best-response function from firm 1  is;

π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14

[tex]\mathbf{\dfrac{\partial \pi_1}{\partial P_1}= 15 - 2P_1 -0.5P_2 =0}[/tex]

[tex]\mathbf{P_1= \dfrac{15-0.5P_2}{2}}[/tex]

The best-response function from firm 2  is;

π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38

[tex]\mathbf{\dfrac{\partial \pi_2}{\partial P_2}= 21 - 2P_2 -0.5P_1 =0}[/tex]

[tex]\mathbf{P_2= \dfrac{21-0.5P_1}{2}}[/tex]

Here we must find the profit for each one of the two stores.

Remember that profit is defined as the difference between the revenue and the cost.

For La Boulangerie we know that they sell Q1 thousand loaves. Each loaf costs $1. Each loaf is sold by P1

Then the profit is just:

P = Q1*(P1 - $1) = (14 − P1 − 0.5*P2)*(P1 - $1)

Which is already written only in terms of P1 and P2.

Similarly, for the other store we will get the profit:

P' = Q2*(P2 - $2) = (19 − 0.5P1 − P2)*(P2 - $2)

Now we must get their best response, which is given by deriving it with respect to the price and making it equal to zero:

For the first store we have:

dP/dP1 = $1 + 14 - 0.52*P2 - 2*P1 = 0

Now we solve it for P1:

P1 = ($1 + 14 - 0.52*P2)/2

Similarly, for the other store we have:

dP'/dP2 = 19 - 0.5*P1 - 2*P2 + $2 = 0

Solving it for P2 it gives:

P2 = (19 - 0.5*P1 + $2)/2

Given:

The expression is [tex]\sqrt{4-6a}[/tex].

To find:

The domain of the expression.

Solution:

We have,

[tex]\sqrt{4-6a}[/tex]

We know that, the square root is defined for only non-negative values. So,

[tex]4-6a\geq 0[/tex]

[tex]4\geq 6a[/tex]

Divide both sides by 6.

[tex]\dfrac{4}{6}\geq a[/tex]

[tex]\dfrac{2}{3}\geq a[/tex]

Thus, the value of variable less than [tex]\dfrac{2}{3}[/tex] make any sense.

Therefore, the domain of the given expression is [tex](-\infty,\dfrac{2}{3}][/tex].

The domain of a function is the set of input values the function can take

The domain of the expression is: [tex]\mathbf{(-\infty, \frac 23]}[/tex]

The expression is given as:

[tex]\mathbf{\sqrt{4 - 6a}}[/tex]

Set the radicand to 0

[tex]\mathbf{4 - 6a = 0}[/tex]

Add 6a to both sides

[tex]\mathbf{6a = 4}[/tex]

Divide both sides by 6

[tex]\mathbf{a = \frac 23}[/tex]

This means that, the value of a must not be greater than 2/3.

Hence, the domain of the expression is: [tex]\mathbf{(-\infty, \frac 23]}[/tex]

Step-by-step explanation:

The running back's total yardage is 21 yards

From the question we are given the following parameters

Distance travelled in the first half of the game is 9 yards

Distance travelled in the second half of the game is 12 years

In order to determine the running back's total yardage, we will take the sum of the distance travelled as shown

Total distance travelled = 9 yards + 12 yards

Total distance travelled = 21 yards

Hence the running back's total yardage is 21 yards

Answer:

f = 4/3

Step-by-step explanation:

-16f + 13 = 2f - 11

24 = 18f

Divide

24/18 = f

4/3 = f

[tex] - 16f + 13 = 2f - 11[/tex]

Subtract sides -13

[tex] - 16f + 13 - 13 = 2f - 11 - 13 \\ [/tex]

[tex] - 16f = 2f - 24[/tex]

Subtract sides -2f

[tex] - 16f - 2f = 2f - 2f - 24[/tex]

[tex] - 18f = - 24[/tex]

Negatives simplifies

[tex]18f = 24[/tex]

Divided sides by 18

[tex] \frac{18}{18}f = \frac{24}{18} \\ [/tex]

[tex]f = \frac{4}{3} \\ [/tex]

Answer:

1 hour/ 32 miles

Step-by-step explanation:

Answer:

A = 28

B = 22

Step-by-step explanation:

All money will be recorded in pennies

Let A = the 45 Bulb

Let B = the 65 bulb

A + B = 50                                  (1)

45A + 65B = 2690                    (2)

Multiply (1) by   45 and subtract that from (2)

45A + 65B = 2690

45A + 45B = 2250        Subtract

          20B =   440

              B = 22

A + B = 50

A + 22 = 50

A = 50 - 22

B = 28

Check

45*28 + 22* 65  =

1260 +  1430 = 2690
