Answer:

-7

Step-by-step explanation:

Given inequality:

[tex]4x - 12 \leq 16 + 8x[/tex]

Subtract 4x from both sides:

[tex]\implies 4x - 12-4x \leq 16 + 8x -4x[/tex]

[tex]\implies -12\leq 16+4x[/tex]

Subtract 16 from both sides:

[tex]\implies -12-16\leq 16+4x-16[/tex]

[tex]\implies -28\leq 4x[/tex]

[tex]\implies 4x \geq -28[/tex]

Divide both sides by 4:

[tex]\implies 4x \div 4 \geq -28 \div 4[/tex]

[tex]\implies x \geq -7[/tex]

This means that x is equal to or greater than -7.

Therefore, the value of x that is in the solution set of the inequality is -7 as -10, -9 and -8 are all less than -7.

Answer:

x ≥ -7

Step-by-step explanation:

Given inequation,

→ 4x - 12 ≤ 16 + 8x

Then the value of x will be,

→ 4x - 12 ≤ 16 + 8x

→ 4x - 8x ≤ 16 + 12

→ -4x ≤ 28

→ x ≥ 28/-4

→ [ x ≥ -7 ]

Hence, the value of x is -7.

Answer:

y = - [tex]\frac{3}{4}[/tex] x - 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (- 12, 4 ) and (x₂, y₂ ) = (0, - 5 ) ← coordinates of 2 end stars

m = [tex]\frac{-5-4}{0-(-12)}[/tex] = [tex]\frac{-9}{0+12}[/tex] = [tex]\frac{-9}{12}[/tex] = - [tex]\frac{3}{4}[/tex]

the lowest star is on the y- axis at (0, - 5 ) ⇒ c = - 5

y = - [tex]\frac{3}{4}[/tex] x - 5

The value of x is 15 and the value of y is 4 for the given triangle.

According to the question,

We have the following information:

We have a figure of triangle and a line parallel to the base is drawn. Some measurements of the sides are given.

Now, to find the values of x and y, we will use Basic Proportionality theorem which states that the ratio of the corresponding sides are equal.

For the larger triangle, we have:

12/y = 18/6

Using the cross multiplication method:

y = 12*6/18

y = 4

Now, using the same theorem for the smaller triangle:

12/y = x/5

12/4 = x/5

Using the cross multiplication method:

x = 15

Hence, the value of x is 15 and the value of y is 4 for the given triangle.

A. The length of the side of original garden is 4 m

B. The width of the new garden is 5m

C. The length of the new garden is 7m

D. The area of the new garden is 35 m²

Let the side of the garden = x m.

area = x² m²

From the question, we have

The new length is (x+3) m and the new width is (x+1) m.

Then the new area = (x+3)(x+1) m².

(x+3)(x+1)=x²+19

⇒ x²+3x+x+3=x²+19

⇒ 4x+3=19

⇒ 4x=19-3

⇒ 4x=16

⇒ x = 4 m

The length of the side of original garden is 4 m

new length = (x+3) m = (4+3)m = 7 m

new width = (x+1) = (4+1) = 5 m

new area = (x+3)(x+1) m² = 7*5 = 35 m²

[tex]x=6, y=-2[/tex]

Step-by-step explanation:

[tex]-2=3x-20 \\ \\ 3x=18 \\ \\ x=6 \\ \\ \therefore x=6, y=-2[/tex]

Answer:

The answer is x = 6. If you want to solve the equation by inputting the x and y value, then take the x value and input it into the equation as well as the y value.

Step-by-step explanation:

To solve this equation, plug in the value equal to y and solve for x. The first thing you have to do is make the equation -2 = 4x - 20, since we already have the value for y which is given in the question. Then add 20 to both sides of the equation. We now have 18 = 3x, divide both sides by 3 and you have your answer.

Hence, X = 6.

The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A it is true.

The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A. A determinant of an n×n matrix can be defined as a sum of multiples of determinants of (n−1)×(n−1) sub matrices.

This is done by deleting the row and column which the elements belong and then finding the determinant by considering the remaining elements. Then find the co factor of the elements. It is done by multiplying the minor of the element with -1i+j. If Mij is the minor, then co factor, [tex]c_{ij}[/tex] [tex]= -1^{i+j}[/tex] + [tex]m_{ij}[/tex].

Step-by-step explanation:

<76 & < 2 are vertical angles, which means they are congruent. <1 & <2 are supplements, meaning when you add them up they equal 180 degrees (180-76=104 degrees). <1 & <4 are vertical angles. Using the Alternating Exterior Angles Theorem (AIA), <2 & <7 are congurent. Using the same theorem, <1 & < 8 are congruent. <7 & <5 are supplements, and so is <8 & <6.

What is the slope of line?

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1). x1 and y1 are represented by the first point's coordinates. The second points are located at x2, y2, and their locations. Whichever point you choose to classify as the first and which as the second doesn't matter.

We know that formula two find the slope of the line joining two points which is
