What is the solution?

Answers

Answer: -2.25 = x

Step-by-step explanation:

The model represents the equation:

-1(6) = 4x + 1(3)

-6 = 4x + 3

SUBTRACT 3 FROM BOTH SIDES

-9 = 4x

DIVIDE BOTH SIDES BY 4

-2.25 = x

answer: -2

explanation: the equation is -5=4x+3 the you would subtract 3 from both sides to get -8=4x then you divide 4 and x will equal -2

What are the slope and Y-intercept of the graph of the linear function shown on the grid?

Answers

Answer:

Slope = 2 and y-intercept = 8

Step-by-step explanation:

Use slope formula

m=y2-y1/x2-x1

m=16-12/4-2

m=4/2

Simplify

m=2

To find the y-intercept use point slope formula

y-y1=m(x-x1)

y-12=2(x-2)

y-12=2x-4

Add 12 to both sides

y=2x+8

So, 8 is the y-intercept or (0,8)

Choose 2 ordered pairs on the number line; i chose (0,125) and (2,235)

The formula for slope (m) is m = y2 - y1 / x2 - x1

In this problem, it would be:

m = 235 - 125 / 2 - 0

A triangle has three angles 5x, 9x and 4x. as described below. Find the value of x
and the value of each angle.

Answers

Answer:

the value of x=10°

Step-by-step explanation:

hey there!

as there is given angles of the triangle i.e. 5x,9x,4x

now adding all of them,

5x +4x+9x=180 (reason: sum of angle of a triangle is 180°)

18x=180

x=180/18

x=10

therefore the value of x is 10

now the value of each angle is;

5x= 5*10=50

4x=4*10=40

9x=9*10=90

You multiply two integers. You increase one of them by 1 and decrease the other
by 1. The product increases by 6. What integers could you have multiplied?

Answers

Integers are numbers without decimals

The integers could you have multiplied are 9 and 2

Let the numbers be x and y

So, we have:

[tex]\mathbf{x \times y}[/tex]

Increase x by 1 and reduce y by 1.

So, we have

[tex]\mathbf{(x +1) \times (y -1) = 6 + xy }[/tex]

Open brackets

[tex]\mathbf{xy -x + y - 1 = 6 + xy}[/tex]

Subtract xy from both sides

[tex]\mathbf{ -x + y - 1 = 6}[/tex]

Collect like terms

[tex]\mathbf{ -x + y = 6 + 1}[/tex]

[tex]\mathbf{ -x + y = 7}[/tex]

Rewrite as:

[tex]\mathbf{ y -x= 7}[/tex]

The above means that, the difference between the integers is 7.

There are several integers that fit the above description;

One possibility is: 9 and 2

What is the area of triangle DEF

Answers

Answer:

76.5 cm²

Step-by-step explanation:

Given the triangles are similar , then

ratio of sides = a : b , so

ratio of areas = a² : b²

Here ratio of sides = 9 : 13.5 = 2 : 3

ratio of areas = 2² : 3² = 4 : 9

let x be the area of Δ DEF and using proportion

[tex]\frac{4}{34}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

4x = 306 ( divide both sides by 4 )

x = 76.5

The area of Δ DEF = 76.5 cm²

Answer:

x = 1.5 or x = 0.5

Step-by-step explanation:

Given equation:

4x² - 8x + 3 = 0

Find the discriminant:

D = b² - 4ac = (-8)² - 4*4*3 = 16

The roots are:

x = (-b ± √D)/2a = (8 ± √16)/(2*4) = (8 ± 4)/8 = 1 ± 1/2x = 1.5 or x = 0.5
4x²-8x+3=0

So

x=(8±√8²-4²(3))/2(4)x=(8±√64-48)/8x=(8±4)/8x=1±1/2

Step-by-step explanation:

We know that half of QS is x+25 and half of diagonal PR is 2x+5.

We can tell that x+25 = 2x+5 because both of these are sides of an isosceles triangle ORS. Since we know that, we can find out the diagonal QS by finding x.

2x+5 = x+25 => x = 20

Half of diagonal QS = 20 +25

= 45

Then we can double the half of diagonal QS to find out the diagonal QS.

45 x 2 = 90

Autobiography of indian mathematician Aryabhatta

will mark brainlist if the answer is correct : )​

Answers

Aryabhata, also called Aryabhata I or Aryabhata the Elder, (born 476, possibly Ashmaka or Kusumapura, India), astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta (Patna), then the capital of the Gupta dynasty—where he composed at least two works, Aryabhatiya (c. 499) and the now lost Aryabhatasiddhanta.

Aryabhatasiddhanta circulated mainly in the northwest of India and, through the Sāsānian dynasty (224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.

Mark as brainlist ❤️❤️

Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathematics and astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita (“Mathematics”), Kala-kriya (“Time Calculations”), and Gola (“Sphere”).
