The steps are;

Let us assume the quadratic equation x² - 2x + 1 = 0

To solve this by factoring;

Step 1: We will first look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant andthe coefficient of x²

For the given equation, the two values are -1 and -1

The quadratic equation becomes;

x² - 1x - 1x + 1 = 0

x² - x - x + 1 = 0

(x²-x)-1(x-1) = 0

Step  2: Factorize the common value from both brackets

x(x-1)-1(x-1) = 0

x-1 = 0 and x - 1 = 0

x = 1twice

The given steps are the ways you can solve quadratic equations in one variable using factoring method

Answer:

A

Step-by-step explanation:

21 yards and Total cost of $146.58

p = 1 yard

Equation: 21p = 146.58

p = 146.58/21

p = 6.98

21p=146.58 will describe the equation and the amount paid for each yard is $6.98 so option (A) will be correct.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Amount of fabric = 21 yards

Since cost per yard of fabric is given by p

So,

The total cost of fabric = Amount of fabric ×  cost per yard

146.58 = 21p

21p=146.58

Now,

p = 146.58/21 = 6.98.

Hence "21p=146.58 will describe the equation and the amount paid for each yard is $6.98".

Answer:

m∠2 = 37°

m∠3 = 143°

m∠4 = 37°

Step-by-step explanation:

From the figure attached,

Two arms of the scissors represent he two lines intersecting each other at a point forming pairs of vertical angles ∠1, ∠3 and ∠2, ∠4.

By the definition of vertical angles,

∠1 ≅ ∠3 and ∠2 ≅ ∠4

Since, m∠1 = 143°

Therefore, m∠1 = m∠3 = 143°

m∠1 + m∠2 = 180° [Since linear pair of angles are supplementary]

143° + m∠2 = 180°

m∠2 = 180° - 143° = 37°

Therefore, m∠2 = m∠4 = 37°  

Answer:

The correct option is;

Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function

Step-by-step explanation:

Given that a function maps a given value of the input variable, to the output variable, we have that a relation that has two values of the dependent variable, for a given dependent variable is not a function

Therefore, a graph in which at one given value of the input variable, x, there are two values of the output variable y is not a graph of a function

With the vertical line test, if a vertical line drawn at any suitable location on the graph, intercepts the graph at more than two points, then the relationship shown on the graph is not a function.

Answer:

y = ✔ 1x+ ✔ -3

Step-by-step explanation:

The equation of the line passing through the points (2, -1) and (10, 7) is y =  x - 3.

The point slope form of a line is given by -

y - y₁ = m(x - x₁)

Given is a line that passes through the points (2, -1) and (10, 7).

The point - slope form of a line is given by the general equation -

y - y₁ = m(x - x₁)

We will find the slope of the line as follows -

m = (7 + 1)/(10 - 2) = 8/8 = 1

The line passes through the point (2, -1), so we can write the equation of line as -

y - (- 1) = x - 2

y + 1 = x - 2

x - y = 3

y =  x - 3

Therefore, the equation of the line passing through the points (2, -1) and (10, 7) is y =  x - 3.

Answer:

a)30-100/1000 • 120

Step-by-step explanation:

Given:

Remaining volume of fuel in a cars tank = I - E • D

where,

I = initial volume of fuel

E = fuel efficiency

D = distance traveled.

Carson

I = 30

E = 100

D = 120

Estimated volume of fuel in Carson's tank = I - E • D

= 30 - 100/1000 * 120

a)30-100/1000 • 120

Answer:

A (30-(100/1000)x120)

Step-by-step explanation:

I is a volume quantity, D is a distance quantity, and E is a rate measured as volume/distance.

So ExD gives us volume quantity.

Distance units are consistent (kilometers) but the volume units of E are inconsistent with those of I and the desired answer.

Let's convert E to liters per kilometer. We will use the fact that there are 1000 cubic centimeters per liter.

You get: 30 liter - 100/1000 liters/kilometer x 120 kilometers

In conclusion, this is the calculation that will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters:

30-100/1000x120.

Answer:

16

Step-by-step explanation:

x^2-8x+k is a quadratic expression of the form ax^2 + bx + c.  Here a = 1, b = -8 and c = k.  Focus on x^2-8x and complete the square as follows:  Take half of the coefficient of x (that is, take half of -8) and square the result:

(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4):  (x -4)^2.

Thus, k = 16 turns x^2-8x+k into a perfect square.

Step-by-step explanation:

From the information given ,the value of x is 4

A line segment is simply defined as the portion of a line connecting two points that are known to be the endpoints.

From the information given, we have that;

Line RS has three segments which are line RS, Line ST and line RT, also S is the midpoint between points R and T

Given that;

Then,

RS + ST = RT

Substitute the values

2x + 5x + 4 = 32

collect like terms

7x + 4 = 32

7x = 32 - 4

7x = 28

Make 'x' the subject

x = 28/ 7

x = 4

Thus, the value of x is 4
