Answer:

Converting the equation x^2-20x+13=0 into completing the square method we get: \mathbf{(x-10)^2=87}

Step-by-step explanation:

we are given quadratic equation: x^2-20x+13=0

And we need to convert it into completing the square method.

Completing the square method is of form: a^2-2ab+b^2=(a-b)^2

Looking at the given equation x^2-20x+13=0

We have a = x

then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20

So, 20x in form of 2ab can be written as:  2(x)(10)

So, we need to add and subtract (10)^2 on both sides

x^2-20x+13=0\\x^2-2(x)(10)+(10)^2-(10)^2+13=0\\(x^2-2(x)(10)+(10)^2) \:can\: be\: written\: as\: (x-10)^2 \\(x-10)^2-100+13=0\\(x-10)^2-87=0\\(x-10)^2=87

So, converting the equation x^2-20x+13=0 into completing the square method we get: \mathbf{(x-10)^2=87}

Drag the expressions to the table to show whether the product is less than 3/4, greater than 3/4, or equal to 3/4.
KiRa [710]

A fraction 3/4 is called greater than 3/4 if,

Numerator > denominator,

Otherwise it is less than 3/4 ,

\frac{1}{3}  \times \frac{3}{4}=\frac{1}{4}

$$\begin{aligned}&\frac{5}{2}  \times \frac{3}{4}=\frac{15}{8} \\&\because 8 < 15 \\&\Longrightarrow  \frac{5}{2}\times \frac{3}{4} < 3/4 \\&\frac{7}{7}  \times \frac{3}{4}=\frac{3}{4} \\&\because 3 < 4 \\&\Longrightarrow \frac{3}{4}  \times \frac{3}{4} = 1 \\& \frac{9}{7} \times \frac{3}{4}=\frac{27}{28} \\&\because 28 > 27 \\&\Longrightarrow \frac{5}{5}  \times \frac{3}{4} > \frac{3}{4} \end{aligned}$$

A fraction represents a portion of a total. This entire may refer to a place or a group of places. The Latin word "fraction," which meaning "to break," is the source of the English term "fraction." The distribution of food and supplies as well as the lack of a metal currency were among the mathematical issues that the Egyptians utilized fractions to solve because they were the first civilization to understand fractions.

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions were first written in India with one number above the other, but without a line. The line used to divide the numerator and the denominator was only added by Arabs.

In a garden, 2/3 of the flowers are roses. Of the roses in the garden, 5/12 are yellow and the rest are red. What fraction of th
emmainna [20.7K]
7/18 of the flowers are red roses

because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.

tip: when you see "of" in a fraction problem, it means you can multiply them.

so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!

Which graph represents the solution to the system of inequalities?<br> x + y ≤ 4<br><br> y – x ≥ 1
frosja888 [35]

Given inequalities are

x+y\le4 and

y-x\ge1

Now we will graph both inequalities to get the common region which represents solution.

<u>Work for x+y\le4 </u>

first we graph the line x+y=4 then shade the graph for inequality symbol \le

we can plug any random number for x and find y-value to get points

lets plug x=0 then we get:

x+y=4

0+y=4

y=4

so the point is (0,4)

Similarly we can find more point like (4,0).

Now graph both points and join both points by straight line.

Now we find direction of shading.

pick any test point which is not on that line x+y=4 say (0,0)

and plug it into orinal inequality x+y\le4

0+0\le4

0\le4

which is true.

True means shade in direction of test point. Otherwise we shade in opposite direction.

We will repeat same process for other inequality to graph that.

Hence final graph for the answer will be as shown in attached image.

Triangular region ABC is final answer.
