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....

We know that the square of any number is greater than or equal to zero ;

So if have a number like x :

[tex]( {x})^{2} \geqslant 0[/tex]

_________________________________

Now we have a number which is

( a - b ) ;

So we have :

[tex]( {a - b})^{2} \geqslant 0 [/tex]

##############################

Reminder :

[tex]( {a - b})^{2} = {a}^{2} - 2ab + {b}^{2} [/tex]

##############################

So we have :

[tex] {a}^{2} - 2ab + {b}^{2} \geqslant 0 [/tex]

Both sides plus 2ab :

[tex] {a}^{2} + {b}^{2} \geqslant 2ab [/tex]

Divided both sides by 2 :

[tex] \frac{ {a}^{2} + {b}^{2} }{2} \geqslant ab \\ [/tex]

Answer:

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

The front elevation of the cube will be either a square or a rectangle.

A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.

Given that, a solid shape is made from 4 cubes.

The front face of a cube is square, therefore, the front elevation of 4 cubes will be either a square or a rectangle.

Hence, the front elevation of the cube will be either a square or a rectangle.

Answer:

The rate of change is 1

Step-by-step explanation:

This is because the slope is x, and -4 is just the y-intercept, which has nothing to do with the slope. Because the slope is x, that means that it is positive 1.

Answer:

Rate of Change = 1

Step-by-step explanation:

Rate of Change = Slope = m

y = mx + b

y = (1)x -4

m = 1

Solution,

Change in water level is [tex]1\dfrac{1}{2}\ \text{inches}=\dfrac{3}{2}\ \text{inches}[/tex]

The water level of a lake fell by [tex]1\dfrac{1}{2}[/tex]  inches  during a [tex]1\dfrac{2}{3}\ \text{or}\ \dfrac{5}{3}[/tex]week-long dry spell.

Average rate at which the water level changed  every week is given by :

[tex]R=\dfrac{1\dfrac{1}{2}}{1\dfrac{2}{3}}\\\\R=\dfrac{\dfrac{3}{2}}{\dfrac{5}{3}}\\\\R=\dfrac{3}{2}\times \dfrac{3}{5}\\R=\dfrac{9}{10}\\\\R=0.9[/tex]

Hence, the average rate is 0.9 every week.

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:

The effective annual rate is 11.03%

Step-by-step explanation:

The effective interest rate is calculated through the formula:

[tex]r = (1 + i/n)^n - 1[/tex]

In this formula, r represents the effective interest rate, i represents the stated interest rate or APR, and n represents the number of compounding periods per year.

For a quarterly compounded interest, n=4. The APR i=10.60%=0.106

Given an APR r, the effective annual rate for a quarterly compound is:

[tex]r = (1 + 0.106/4)^4 - 1=1.0265^4-1[/tex]

[tex]r=1.11029-1=0.1103[/tex]

The effective annual rate is 11.03%

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:

x represents the number of hats.

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given, Company A sells hats for $11 per hat plus a fixed $7 shipping and handling fee. Company B sells hats for $8 per hat plus a fixed $16 shipping and handling fee.

Let x be the number of hats and y be the total cost for x hats

For Company A:

per hat charges = 11

charge for x hats = 11 * x

Since, shipping charges = 7

Thus,

Total cost for x hats, y = 11x + 7

For Company B:

per hat charges = 8

charge for x hats = 8 * x

Since shipping charges = 16

Thus,

Total cost for x hats, y = 8x + 16

If the Cost is the same,

11x + 7 = 8x + 16

3x = 9

x = 3

therefore, If we order 3 hats then the cost from both companies will be the same. and x represents the number of hats.

Answer:

There were 14 red-haired people accumulated in Beaumont, for this year.

Step-by-step explanation:

        Number of dark haired people = 180

        Number of red haired people = 260

        Number of blonde haired people = 360

        Number of dark haired people = 470

        Number of red haired people = 270

        Number of blonde haired people = 330

        Number of dark haired = 47

        Number of red haired = 90

        Number of blonde haired = 86

        Number of dark haired people = 31

        Number of red haired people = 66

        Number of blonde haired people = 71

Compute the accumulation of red-haired people in Beaumont, for this year as follows:

Red hair = #Moved in - #Moved out + #Newborn - #Deaths

              = 260 - 270 + 90 - 66

              = 14

Thus, there were 14 red-haired people accumulated in Beaumont, for this year.
