help bros i give up ggs jk but i need atleast 90 percent to be free

Answer: A

Step-by-step explanation:

3x² - 10x + 5 = 0

a = 3      b = -10     c = 5

Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions

=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]

[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).

Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]

Given quadratic equation

[tex]3x^{2} -10x+5=0[/tex]

a = 3, b = -10, c = 5

Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]

⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]

⇒ [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex]

Hence,  [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.

Answer:

Shane started the problem correctly

Step-by-step explanation:

We are given problem (-5) - (-1 3/4).

Mariah started the problem as (-5) + 1 - 3/4

Shane started the problem as (-5) + 1 + 3/4

We need to find who started the problem correctly.

The problem should be started by converting the mixed fraction into improper fraction i,e

[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]

Now we will solve bracket by multiplying -1 with term inside the bracket i.e

[tex]=-5+\frac{7}{4}[/tex]

[tex]= \frac{-13}{4}[/tex]

Let's compare both the procedures now:

Mariah:

[tex](-5) + 1 - \frac{3}{4}[/tex]

[tex]=(-5) - \frac{1}{4}[/tex]

[tex]=\frac{-21}{4}[/tex]

Therefore, Mariah did not start the problem correctly.

Shane:

[tex](-5) + 1 + \frac{3}{4}[/tex]

[tex]= -5 + \frac{7}{4}[/tex]

[tex]= \frac{-13}{4}[/tex]

Therefore, Shane started the problem correctly.

Step-by-step explanation:

So! Usually, I start by finding the y intercept. The line hits it at -3. After that, you would use RISE/RUN. When using that, you can see that you go up 1, to the right to. Since you are going up and to the right, it's a positive slope (1/2).

Answer:

w=6

Step-by-step explanation:

−5(w−5)=−5

= divide both sides by -5

=w-5=1

add 5 to both sides

= w=6

Answer:

w=6

Step-by-step explanation:

5(w−5)=−5

(−5)(w)+(−5)(−5)=−5(Distribute)

−5w+25=−5

Step 2: Subtract 25 from both sides.

−5w+25−25=−5−25

−5w=−30

Step 3: Divide both sides by -5.

−5w−5=−30−5

w=6

Answer:2/3

Step-by-step explanation:

The probability that the selected student is a sophomore given that he is a boy will be 5/12.

Probability refers to a possibility that deals with the occurrence of random events.

we need to select the probability that the selected student is a sophomore given that he is a boy;

In this case;

P(B) = P(boy)

P(A) = P(sophomore)

The total number of students which is 12 + 18 = 30

From the table;

P(B) = 12/30

P(A n B) = 5/30

So;

P(A|B) = 5/30 / 12/30

= 5/30 x 30/12 = 5/12

Hence, the probability that the selected student is a sophomore given that he is a boy will be 5/12.

The image A'B'C' is formed by an isometric transformation because all of the vertices moved 2 units right and 2 units down, the correct option is B.

Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.

Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.

Reflection is creating a mirror image of the object, which is same in shape and size but only the coordinates have been changed.

Translation is moving the object, up, down, left or right on the coordinate axis.

Dilation is changing the size of the object, the original object is either enlarged or compressd by certain scale factor.

The object ABC shown in the image has coordinates A ( -2, 5), B (-5, -3), C(1, -3) and,

The image has the cooridnates A'(0,3), B'(-5,-3) , C'(3, -5).

The coordinates have been transformed by translation.

The transformation is an isometric transformation could have been applied because all of the vertices moved 2 units right and 2 units down.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

28 - 12 √(n ÷ 2)

Sustitute n = 4

= 28 - 12 √(4 ÷ 2)

= 28 - 12√2

= 28 - 12 x 1.414

= 28 - 16.968

Step-by-step explanation:

Answer:

The correct option is 72.

Step-by-step explanation:

To calculate this, we first let x represent the number games that must be played to make at least $45.

Based on this, we can have an in equality equation as follows:

2.50x - 135 ≥ 45

We can now solve for x as follows:

2.50x ≥ 135 + 45

2.50x ≥ 180

x ≥ 180 / 2.50

x ≥ 72

This implies that at leats 72 games must be played to make at least $45. Therefore, the correct option is 72.

Her monthly payment, if she is considering a three-year loan is $373.47

Given the cost of the motorcycle to be $14000

If the tax rate is 6.75%, the total cost plus tax is expressed as:

Final cost = 14000+(0.0675 * 14000)

Cost of motorcycle = 14000 + 945

Cost of motorcycle = $14945

If she plans to make a down payment of $1,500 before the sales tax is applied, then;

Balance = 14945 - 1500

Balance = $13,445

If she considers  a three-year loan, her monthly payment will be ;

Monthly payment = 13,445/36

Monthly payment = $373.47

Hence her monthly payment if she is considering a three-year loan is $373.47

There are total 4 Diamonds.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Ratio of diamonds to emeralds = 1:4.

Total = 16 emeralds

let the common ratio be x.

Emeralds = 4x and Diamonds = x

So, 4x = 16

x= 4

Thus, number of diamonds

= 4

Hence, there are 4 diamonds.
