The only option that is not viable to solve the systems of equations is:

D. Substitute y = 6/5x - 12 into the first equation

Given the systems of equations,

2x + y = 20 ----> equation 1

6x - 5y = 12 ----> equation 2

In order to solve the system of equations using the substitution method, rewrite 2x + y = 20:

2x + y - 2x = 20 - 2x

y = 20 - 2x

Or

2x = 20 - y

x = 10 - 1/2y

Or

6x - 5y = 12

-5y = -6x + 12

y = -6/5x - 12/5

or

6x = 12 + 5y

x = 2 + 5/6y

It follows that the least integer greater than log√₇ √50 is 3.

We have a logarithm function that is given to us.

Let x = log√₇ √50

We get that:√ 7 ˣ = √ 50

So, we must find an integer x, such that √ 7 ˣ > √ 50.

We know that √ 49 = 7

√ 7 ˣ > 7

7 ⁰°⁵ˣ  > √ 7

x / 2 > 1

x > 2

In this case, x = 3 will be the least integer to satisfy this inequality.

Therefore, it follows that the least integer greater than log√₇ √50 is 3.

The length of each side will be 14.8 inches approx.

It's given that an Octagon sign is drawn out of a square by cutting out triangles from its corners and the total length of the stop sign is 36 inches. We know that squares are Right Angled at each side so in the picture mentioned below, we apply Pythagoras' theorem to find an equation for the side of the sign.

                     =>  [tex]s^{2} = x^{2} + x^{2}[/tex]

                     =>  [tex]s^{2} = 2x^{2}[/tex]                  ----> Eq. 1

Also, it is a square. So, the measurement of length from side to side

                     => 2x + s = 36 inch      ----> Eq. 2

By solving Eq.1 we get s = (√2)(x), Putting this value in Eq.2

                    => s = 36 - 2x    =>    (√2)(x) = 36 - 2x

                    => x(2 + √2 ) = 36   =>  x = 36/(2+√2)

Putting this value of x in Eq.1 , s^2 = 2(x^2)

                   => s = √2.(x)       =>  s = √2 (36/(2 + √2)

                   => s = 14.8

Hence, the length of each side of the sign will be 14.81-inch approx.

The system of equations that could be used to determine the number of pounds of apples sold and the number of pounds of strawberries sold will be x + y = 35 and 2x + 3y = 80.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, each pound of apples sells for $2 and each pound of strawberries sells for $3. Aiden made $80 from selling a total of 35 pounds of apples and strawberries.

Suppose the number of pounds of apples and strawberries is x and y respectively.

If the total of 35 pounds of apples and strawberries as a result,

x + y = 35-------(1)

If each pound of apples sells for $2 and each pound of strawberries sells for $3. Aiden made $80 then,

2x + 3y = 80---------(2)

Multiply equation 1 by 2 and subtract from equation 2 as

2x + 3y -2(x+y) = 80 - 2(35)

y = 10

Substitute the value of y we get x = 25

As a result, there are 25 pounds of apples and 10 pounds of strawberries in all.

Thus, the system of equations that could be used to determine the number of pounds of apples sold and the number of pounds of strawberries sold will be x + y = 35 and 2x + 3y = 80.

The statement that is the recursive definition of f is f(1) = -2 f(n) = f(n - 1) + 2  for n > 2

The function definition is given as

f(n) = -4 +2n for n > 1

Start by calculating f(2), f(3) and f(4)

So, we have

f(2) = -4 +2(2)

f(2) = 0

f(3) = -4 +2(3)

f(3) = 2

f(4) = -4 +2(4)

f(4) = 4

In the above computation, we can see that the sequence is an arithmetic sequence with a common difference of 2

So, we have

f(n) = f(n - 1) + 2

Also, we have

No extraneous solution to the equation:

The equation is:

[tex]x^{1/2}[/tex] - [tex](x- 5)^{1/2}[/tex] = 2

To know whether the equation has an extraneous solution first we need to find the value of x.

[tex]x^{1/2}[/tex] - 2 = [tex](x - 5)^{1/2}[/tex]

[tex]x^{1/2} - 2[/tex] = [tex](x - 5)^{1/2}[/tex]

Now squaring both sides of the equation we have:

[tex](x^{1/2} - 2)^{2}[/tex] = x - 5

x - 4[tex]x^{1/2}[/tex] + 4 = x -5

[tex]x^{1/2}[/tex] = -9/4

x = 81/16

Now we have to put the value of x in the equation.

[tex](81/16)^{1/2}[/tex] - [tex](81/16 - 5)^{1/2}[/tex] =2

9/4 - 1/4 =2

8/4 = 2

2 =2

If the approximated number is given as 6.3 Then the error interval of x is 6.24≤x≤6.35

A value or quantity that is nearly but not exactly correct.

The number is given as x.

So, we have:

The smallest number that can be approximated to 6.3 is 6.25 (to 1 decimal place), while the largest number is 6.34

Given that there are possibilities of error, the lower and upper bound of the error interval would be:

The proof of DE is parallel to BC in the given triangle is shown.

As per the given data in the question;

A, B and C are the vertices of a triangle.

Whereas,

D lies at the midpoint of AB.

E lies at  the midpoint of AC.

The mid piont formula is;

Mid point = (x₁ + x₂ / 2, y₁ + y₂ / 2)

The coordinates of D is found by the mid point formula of coordinates.

Put the coordinates of A (4, 6) and B (2,-2).

D = (4 + 2 / 2, 6 - 2 / 2)

D = (3, 2)

The coordinates of E is found by the mid point formula of coordinates.

Put the coordinates of A (4, 6) and C (-2,-4)

E = (4 - 2 / 2, 6 - 4 / 2)

E = (1, 1)

Now, the slope is calculated by;

m of DE = (y₂ -  y₁)/(x₂ - x₁)

The slope of E is

m of DE = (1 - 2)/(1 - 3) = 1/3

Slope of BC

M of BC = (-4 + 2)/(-4 - 2)

M of BC = 1/2
