Find the value of x

y= 40/39-47x/30

x=40/47-39y/47

Step-by-step explanation:

The general equation of any linear equation is y = mx + c where m is yhe gradient.

78y + 94x =80

78y = -94x + 80

y = -94y/78 + 80/78

y = -47y/39 + 40/39

Therefore the slope is -47/39

Step-by-step explanation:

it is undefined because its a vertical line.

Answer:

slope is undefined u

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (1, 0 )

m = [tex]\frac{0-(-3)}{1-1}[/tex] = [tex]\frac{0+3}{0}[/tex] = [tex]\frac{3}{0}[/tex]

Since division by zero is undefined then the slope of the line is undefined

Answer:

X + 0.75 x 3 = 5.88

Step-by-step explanation:

Explicación paso a paso:

X = 1k de manzanas

0.75 = lo que aumenta el valor de X

3 = los 3k de manzanas que equivalen a 5.88 como resultado

esa es la ecuacion, solo queda resolverla despejando las X del kilo para descubrir cuanto cuesta un solo kilo de manzanas

The cost of the apples was $1.21 per kg before winters.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have in winters, the price of apples suddenly rose by $0.75 per kilo. Sam bought 3 kilos of apples at the new price, for a total of $5.88​.

Assume that the cost before winters be $x per kg. Then, during the winters, the cost would be $(x + 0.75) per kg.

Now -

3 kg of apple cost $5.88

1 kg of apple will cost $(5.88/3) = $1.96 per kg

So, we can write -

(x + 0.75) = 1.96

x = 1.21

Therefore, the cost of the apples was $1.21 per kg before winters.

======================================

Explanation:

7+6 = 13. Divide this over 5 to get 13/5 = 2 remainder 3. The quotient 2 is something we don't care about. We only worry about the remainder. Therefore 7+6 = 3 (mod 5)

-------------

2+1 = 3 (mod 5) for similar reasoning as above. 3/5 = 0 remainder 3.

-------------

20 = 9 (mod 11) since 20/11 = 1 remainder 9. Imagine you had 20 cookies and 11 friends. Each friend would get 1 whole cookie (quotient) and there could be 9 left over (remainder).

-------------

35/11 = 3 remainder 2

Or you could use repeated subtraction like so to find the remainder

35-11 = 24

24-11 = 13

13-11 = 2

The last result (2) is smaller than 11, so we stop here and this is the remainder.

Therefore, 35 = 2 (mod 11)

--------------

Here's another way to think of it. Consider you have $35 in your pocket. Let's say a store is selling trinkets for $11 each. We can pose these key questions:

The answer to the first question is 3 trinkets because 3*11 = 33 dollars is under the budget of $35. The amount left over is 35-33 = 2 dollars which is the remainder. It's not larger than 11, so we cannot buy any more trinkets at this point.

Step-by-step explanation:

To graph the linear inequality 2y > x - 2, we need to rewrite it in slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.

First, let's isolate y on one side by dividing the entire inequality by 2:

y > (1/2)x - 1

Now we have the inequality in slope-intercept form. The slope is 1/2, which means the line will have a positive slope, and the y-intercept is -1, indicating that the line crosses the y-axis at (0, -1).

To graph this inequality, we draw a dotted line with a slope of 1/2 and a y-intercept of -1. Since the inequality is greater than (y >), we use a dotted line to show that points on the line itself are not included in the solution.

Next, we determine whether to shade above or below the line. Since y is greater than the line, we shade above the line. This shading represents the solution set of the inequality.

In summary, the graph of the linear inequality 2y > x - 2 is a dotted line with a positive slope of 1/2 and a y-intercept of -1, and the area above the line is shaded.

Answer:

A. x ≤ -3 or x > 7

Step-by-step explanation:

Solve the first equation.

-6x + 14 < -28

Subtract 14 from both sides.

-6x < -42

Divide both sides by -6. REMEMBER: when dividing an inequality by a negative number, flip the sign.

x > 7.

Solve the second equation.

9x + 15 ≤ -12

Subtract 15 from both sides.

9x ≤ -27

Divide both sides by 9.

x ≤ -3.

Your answer is A.

Answer:

g(x) = x² - 4 is already in form of a variable, I.e., x

g(4x) takes another variable, I.e., 4x

Same as before, 4x takes over x:

=> g(4x) = (4x)² - 4

=> g(4x) = 16x² - 4

OR

=> g(4x) = 4{4x² - 1}

[tex]\large{\rm{\underline{\underline{Answer:}}}}[/tex]

Now we have g(4x). This means, we have to replace x by 4x and correspondence to this, the equation will change. I.e.

⇛ g(4x) = (4x)² - 4

⇛ g(4x) = 16x² - 4 / 4(4x² - 1) [answer]
