Christopher is solving a system of equations that has one solution and can be seen in Option C.

A system of equations is more than one equation that can be solved together to get a unique solution. In this situation, the power of the equation must be in one degree.

A quadratic equation is an algebraic equation whose power is raised to the second degree.

However, if their power is not in one degree, they are regarded as a quadratic equation and it usually produces two solutions.

From the given options, we can see that only option c is not a quadratic equation, Hence, it is the right answer.

The measure of angles are opposite angles where ∠2 = 37°'

Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Given data ,

Let the two intersecting lines be m and n

where the measure of ∠4 = 37°

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

So , the measure of ∠2 = ∠4

On simplifying , we get

The measure of angle ∠2 = 37°

Hence , the angle is ∠2 = 37°

Answer:

  1

Step-by-step explanation:

There are a couple of identities that come into play here:

  a³ -b³ = (a -b)(a² +ab +b²)

  (x^a)/(x^b) = x^(a-b)

  (x^a)^b = x^(ab)

  (x^a)(x^b) = x^(a+b)

_____

These mean we can simplify the expression as follows.

  [tex]\left(\dfrac{x^{a}}{x^{b}}\right)^{a^2+ab+b^2}\times\left(\dfrac{x^{b}}{x^{c}}\right)^{b^2+bc+c^2}\times\left(\dfrac{x^{c}}{x^{a}}\right)^{c^2+ca+a^2}\\\\=x^{(a-b)(a^2+ab+b^2)}\times x^{(b-c)(b^2+bc+c^2)}\times x^{(c-a)(c^2+ca+a^2)}\\\\=x^{a^3-b^3}\times x^{b^3-c^3}\times x^{c^3-a^3}=x^{(a^3+b^3+c^3)-(a^3+b^3+c^3)}\\\\=x^0=\boxed{1}[/tex]

The expression has a value of 1.

Additional comment

For certain values of x and the exponents, the individual factors may exceed the ability of a calculator to express the value. That is, an attempt at numerical evaluation of this may produce a result different from 1. In any event, the expression is undefined for x=0.

Answer:

y = 4

Step-by-step explanation:

2(4y - 9) = 14

8y - 18 = 14

8y = 32

y = 4

Answer:

y = 4

Step-by-step explanation:

Simplifying

2[4y + -9] = 14

Reorder the terms:

2[-9 + 4y] = 14

[-9 * 2 + 4y * 2] = 14

[-18 + 8y] = 14

Solving

-18 + 8y = 14

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 8y = 14 + 18

Combine like terms: -18 + 18 = 0

0 + 8y = 14 + 18

8y = 14 + 18

Combine like terms: 14 + 18 = 32

8y = 32

Divide each side by '8'.

y = 4

Answer:

the final one

Step-by-step explanation:

to figure this equation out it is easier to add numbers to the angles

for 1 we can have it as 100 and for 2 we can have it as 80

that means 3 is 100 and 4 is 80

100 - 80 is also 100 - 80 so the first one can be proven

100 + 80 = 180 so the second one can be proven

80 = 80 so the third one can be proven

80 + 80 = 100 + 100 is not correct because it turns into 160 = 200 which is incorrect so the last one cannot be proven

Answer:

seventy fourteenths

Step-by-step explanation:

seven = 7

ten fourteenth = 10 fourteenth

one-fourteenth = 1/14, so ten fourteenths = 10/14

7 * 10/14

when multiplying two numbers, multiply the numerators and denominators together separately to get your new numerator and denominator

7 = 7/1 as anything divided by 1 equals itself

7 * 10/14 = 7/1 * 10/14 = (7*10) / (1*14) = 70/14 = seventy fourteenths

Answer:

17 feet

Step-by-step explanation:

Since a square has 4 sides, you have to do 68 / 4 to find one of the sides.

68/4 = 17

And to check, if you add up all sides...

17+17+17+17 = 68

Answer:

m = 50

Step-by-step explanation:

∠ D and ∠ A are vertically opposite angles and are congruent , then

m - 130 = 20 - 2m ( add 2m to both sides )

3m - 130 = 20 ( add 130 to both sides )

3m = 150 ( divide both sides by 3 )

m = 50

The equation 17 - 4x - 4= - 10x + 13 + 6x is a linear equation

The true statement about Bob's solution is (d) There are infinitely many solutions since 13 = 13 is a true statement.​

The equation and the steps are given as:

17 - 4x - 4= - 10x + 13 + 6x

13 - 4x = -4x + 13

13 = 13

The final step where both sides of the equation are represented by the constant value 13 means that:

The equation has infinitely many solutions

Hence, the true statement about Bob's solution is (d) There are infinitely many solutions since 13 = 13 is a true statement.​
