Step-by-step explanation:

The solution to the equation using graph is x= -0.62 or x = 1.62.

What is equation?

A mathematical equation may be a formula that uses the equals sign to represent the equality of two expressions.

Main Body:

For [tex]-x^{2} +y = 1[/tex]

We make y the subject to obtain

[tex]y = x^{2} +1[/tex]

We can easily graph this function, because we just have to transform the graph [tex]y = x^{2}[/tex] of  by shifting the intercept up to 1.

As for the straight line, -x +y = 2

We find the intercepts as follows,

When y = 0 , x = -2

When x = 0 , y = 2

We plot the points (-2,0)  and (0,2).

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be

x= -0.62 or  x= 1.62

Answer:

h(x)= |x-3|-4

Step-by-step explanation:

If f(x) = |x| is shifted down 4 and right 3 to create h(x), then h(x) = |x - 3| - 4

The function is given

f(x) = |x|

Translation of the shape mean the displacement of the shape from one place  to another place. Some usually used displacements are shifted to right / left and shifted to up / down etc.

First f(x) is shifted down 4

Then the function will become

f(x) = |x| - 4

Then the function shifted right 3

Then the function will be

h(x) = |x - 3| - 4

Hence, if f(x) = |x| is shifted down 4 and right 3 to create h(x), then h(x) = |x - 3| - 4

Answer:√53 or 7.28010988928

Step-by-step explanation:

Answer: Center: (-3, 2). Radius: 4.

Step-by-step explanation:

The x-coordinate of the center of the circle is given by the constant within the parenthesis with variable x. Whatever number makes the equation x + 3 = 0 is the x-coordinate of the center of the circle, which in this case is -3.

The y-coordinate of the center of the circle is given by the constant within the parenthesis with variable y. Whatever number makes the equation y - 2 = 0 is the y-coordinate of the center of the circle, which in this case is -2.

The radius of the circle is the square root of the constant on the other side of the equation. So, r = [tex]\sqrt{16}[/tex] = 4.

The explanation is from the equation of a circle in a graph:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

h and k in this equation stand for the coordinates of the center of the circle, with h being the x-coordinate and k being the y-coordinate. IN your equation, we have:

[tex](x+3)^2 + (y-2)^2 =16[/tex]

Which can also be written as

[tex](x-(-3))^2 + (y-(2))^2=16[/tex]

See the correlation of numbers -3 and 2 with h and k?

Notice also how the equation contains [tex]r^2[/tex], so to find the radius you do [tex]\sqrt{r^2}[/tex].

y-6 = -2/5(x-(-5)
y - 6 = -2/5(x+5)

y -6 = -2/5 x -2

y = -2/5 x -2 + 6

y = -2/5 x + 4

2

y-6 = 5/2 (x-(-5)

y-6 = 5/2 (x+5)

y - 6 = 5/2 x + 25/2

y = 5/2 x + 25/2 + 6

y = 5/2 x  + (25+12)/2

y = 5/2 x + 37/2

If you multiply by 12 you will get rid of all your fractions.

In mathematics, a linear equation is one that may be written in the form where the variables are alphabets, and the coefficients are frequently real integers. An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

It is rather simple to locate both intercepts when an equation is stated in this way (x and y).

The given linear equation is

6 - (3/4)x + (1/3) = (1/2)x + 5

In this equation the fractions are
(3/4), (1/3) and (1/2)

Take the LCM of 4, 3, and 2

LCM(4, 3, 2) = 12

So, if we multiply the equation with the number 12  we can eliminate the fractions.

It is given in the question that:-

Investment of George's friend in startup company = $ 500.

Interest percent = 8 %

Time period of investment = 3 years

We have to find the linear function for this situation.

As this interest is on original investment, the interest will be simple.

Hence,

The linear function for the situation will be :-

Amount at the end of 3 years= Original investment + original investment*Rate*Time/100

The time taken is obtained as 3 years.

We know that radioactivity has to do with the fact that a substances does disintegrate gradually over a period of time.

Let us recall the formula;

N/No = (1/2)^t/t1/2

N = The mass of radioactive atoms at time t

No = The mass of radioactive atoms initially present

t = time taken

t/12 = half life of the radioactive nucleus

Then;

32/50 = (1/2)^t/28

0.64 =  (1/2)^t/28

log 0.64 = t/28 log0.5

t/28 = log(0.64/0.5)

Answer:

x = 3

y = -1

Step-by-step explanation:

4x + 10y = 2        Eq. 1

 x  - 10y = 13       Eq. 2

The result of the sum of Eq. 1 and Eq. 2 is:

4x + x = 5x

10y - 10y = 0y = 0

2 + 13 = 15

Then the result is:

5x = 15

x = 15/5

x = 3

From Eq. 2:

x - 10y = 13

3 - 10y = 13

-10y = 13 - 3

-10y = 10

y = 10/-10

y = -1

Check:

From Eq. 1:

4x + 10y = 2

4*3 + 10*-1 = 2

12 - 10 = 2

The solution of the equation is that the value of x = 3 and y = -1.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The equation will be solved as,

4x + 10y = 2        Eq. 1

x  - 10y = 13       Eq. 2

The result of the sum of Eq. 1 and Eq. 2 is:

4x + x = 5x

10y - 10y = 0y = 0

2 + 13 = 15

Then the result is:

5x = 15

x = 15/5

x = 3

From Eq. 2:

x - 10y = 13

3 - 10y = 13

-10y = 13 - 3

-10y = 10

y = 10/-10

y = -1

Therefore, the solution of the equation is that the value of x = 3 and y = -1.

The elements of AUB is {6, 7, 8, 9, 11} when A = {6,7,8,11} and B = {7,6,7,9}.

According to the question,

We have the following information:

A = {6,7,8,11} and B = {7,6,7,9}

Now, we know that the elements of AUB means that all the elements which are there in both sets but the elements are not supposed to be repeated.

(Please that AUB can also be found using Venn diagram and questions are asked where the question has to be solved by making Venn diagram and representing all the elements in it.)

So, we have the following expression:

AUB = {6,7,8,9,11}

(Now, note that numbers however repeated in sets are not repeated here.)

What is factorization?

Factorization, also known as factoring, is the process of breaking down an object (such as a number, a matrix, or a polynomial) into a product of another object, or factors, which when multiplied together yield the original object (such as the number or matrix) in question.

What is inequality?

A relationship between two expressions or values that are not equal to each other is called an inequality.

Here, we have

Factor out the greatest common factor from each group

x²(x+5) - 4(x+5) = 0

Factor the polynomial by factoring out the greatest common factor, (x+5)

(x+5)(x²-4) = 0

Rewrite 4 as 2².

(x+5)(x²-2²) = 0

(x+5)(x+2)(x-2) = 0

Now,

x+5 = 0

x-2 = 0

x+2 = 0

set x+5 =0 then we get

x = -5

set x+2 =0 then we get

x = -2

set x-2 =0 then we get

x = 2

Hence, the final solution is all the values that make (x+5) (x+2) (x−2)=0 true.

x = −5,−2,2
