Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where [tex]a\neq 0[/tex].

[tex]x^{2} -2x-8=16[/tex]

[tex]x^2-2x-24=0[/tex]

[tex]x^{2} -6x+4x-24=0[/tex]

[tex]x(x-6)+4(x-6)=0[/tex]

[tex](x-6)(x+4)=0[/tex]

x = -3, 5

Answer:

-4 and 4

Step-by-step explanation:

Method 1

Apply Difference of Two Squares Formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]

Given  [tex]x^2-16=0[/tex]

Rewrite 16 as 4²

Therefore, [tex]a^2=x^2[/tex] and [tex]b^2=4^2[/tex]

[tex]\implies a = \sqrt{x^2}=x[/tex]

[tex]\implies b=\sqrt{4^2} =4[/tex]

[tex]\implies x^2-16^2=(x+4)(x-4)[/tex]

[tex]\implies (x+4)(x-4)=0[/tex]

[tex]\implies (x+4)=0 \implies x=-4[/tex]

[tex]\implies (x-4)=0 \implies x=4[/tex]

Method 2

Given equation:

[tex]x^2-16=0[/tex]

Add 16 to both sides:

[tex]\implies x^2-16+16=0 + 16[/tex]

[tex]\implies x^2=16[/tex]

Square root both sides:

[tex]\implies \sqrt{x^2}=\sqrt{16}[/tex]

[tex]\implies x=\pm4[/tex]

Therefore, x = -4, x = 4

The range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

For a set of data, the range is the difference between the maximum and minimum value. It sort of gives an idea of spread of the data.

For this case, we're given that:

Perimeter of a rectangle = 2(length + width)

Let 'l' denotes length, and 'w' denotes width, then we get:

[tex]Perimeter \leq 4\\2(l+w) \leq 4\\2(1.5 + w) \leq 4\\\\\text{Dividing both the sides by 2}\\\\1.5 + w \leq 2\\\\\text{Subtracting 1.5 from both the sides so as to get 'w' on one side}\\\\w \leq 0.5[/tex]

Now since the lowest value of width of a frame can be zero only, therefore, we get:

[tex]0 \leq w \leq 0.5[/tex]

Thus, the range of values 'w' can assume is: 0.5 - 0 = 0.5

Thus, the range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

Answer:

the median is 15, there is no mode.

Step-by-step explanation:

to find the median- put the numbers in order from least to greatest (13,14,14,16,16,19) use a sheet of paper and cross off each number on the ends until you get to the middle. Once you have reached the middle you should have the two numbers 14, 16. Take 14 and 16, add them together and you will get 30. Divide 30 by 2 because there is two numbers for the median. You should end with 15 as your median.

to find the mode- find the number that occurs the most in the set of numbers, in this case all numbers occur the same amount of times, so therefor there is no mode.

Answer: just graph it using the x and y coordinate points

Step-by-step explanation:

Answer:

(-4, -2)

Step-by-step explanation:

Rewrite the equations to make y the subject, so that it's easier to calculate the points on each line:

Equation 1

x - y = -2

⇒ x + 2 = y

⇒ y = x + 2

Equation 2

2x - 3y = -2

⇒ 2x + 2 = 3y

⇒ y = (2/3)x + 2/3

Calculate 2 points on each line:

Equation 1  (blue line on attached graph)

Substitute x = 0 and x = -2 into Equation 1 to create 2 points:

x = 0:   y = 0 + 2  ⇒ (0, 2)

x = -2:   y = -2 + 2  ⇒ (-2, 0)

Plot the points and draw a line through them.

Equation 2 (red line on attached graph)

Substitute x = 2 and x = -1 into Equation 1 to create 2 points:

x = 2:   y = (2/3)(2) + 2/3  ⇒ (2, 2)

x = -1:   y = (2/3)(-1) + 2/3  ⇒ (-1, 0)

Plot the points and draw a line through them.

Solution

The solution is the point where the two lines intersect.

Therefore, the point of intersection is (-4, -2)
