Step-by-step explanation:

please mark brainliest!

Answer:

ok so this is kinda hard to explain but. what I got out of it was since you are doing you know adding pos with neg so listen when you add something like a pos and a neg you put the pos on top right then you take and put the neg on bottom then you cross out how ever many negatives are there until there is no more negatives left right but that means your also gonna have to cross out how ever many neg there are with positives and if there are more negatives than positives your answer will be negative as well then you just count how many positives arent crossed out and then that would be your answer ect.

Answer:

Step-by-step explanation:

y = mx + b.y = 15/13x − 10/13

Answer:

The answer is y = 15x/13 – 10/13.

Step-by-step explanation:

We are given equation

Now, The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Rewrite in slope-intercept form.

15x – 13y = 10

Subtract 15x from both sides of the equation we get,

15x – 15x – 13y = 10 – 15x

-13y = 10 – 15x

Divide each term by -13 and simplify.

-13y/(-13) = 10 – 15x ÷ (-13)

Cancel the common factor of -13

y = -10/13 + 15x/13

Now, Rearrange it

y = 15x/13 – 10/13

Thus, The answer is y = 15x/13 – 10/13.

You can square both the sides and then use the formula for finding the roots of the obtained quadratic equation to find the solution needed.

The statements describing the solutions to the given equations are

Let the quadratic equation be [tex]ax^2 + bx + c = 0[/tex]

Then the solution to this quadratic equation is given as

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Those values of the variables who come out behaving like solutions but when tested, doesn't get proved as solutions to the given equation are called extraneous solutions.

Solutions to an equation means those values of the unknown for which the equation is true.

The given equation is

[tex]\sqrt{x-2} -4 = x - 6[/tex]

Converting that equation to quadratic form, we get

[tex]\sqrt{x-2} -4 = x - 6\\\\\sqrt{x-2} = x - 2\\[/tex]

From the obtained equation, we can see that x-2 is such a number whose square root is it itself. It is true for 2 numbers only.

First 1, and second 0.

Putting these values, we get

[tex]x-2 = 1\\x = 2+1 = 3\\\\x-2 = 0\\x = 2[/tex]

Thus, there are two solutions to the given equation. They are x = 2, and x = 3

Testing both the solutions by putting them in the given equation.

Case 1: x = 2

[tex]\sqrt{x-2} -4 = x - 6\\\sqrt{2-2} - 4 = 2 - 6\\0-4 = -4\\-4 = -4[/tex]

This is correct equality, thus, x = 2 is a correct solution.

Case 2: x = 3

[tex]\sqrt{x-2} -4 = x - 6\\\\\sqrt{3-2} - 4 = 3 - 6\\1 - 4 = -3\\-3 = -3[/tex]

This is correct equality, thus, x = 3 is a correct solution.

The zeroes(also called solutions) of [tex]x^2 - 5x + 6 = 0[/tex] is found as:

[tex]x^2 - 5x + 6 = 0\\x^2 - 3x - 2x +6 = 0\\(x-2)(x-3) = 0\\x = 2, x = 3[/tex]

Thus, the The zeroes(also called solutions) of [tex]x^2 - 5x + 6 = 0[/tex]  are possible solutions to the radical equation given.

Exact answer: [tex]x = \frac{\sqrt{601}}{2}\\\\[/tex]

Approximate answer: [tex]x \approx 12.2577[/tex]

====================================================

How to find the answer:

Focus on the largest triangle. It appears to be a right triangle. If so, then we can use the pythagorean theorem to get the following:

[tex]a^2 + b^2 = c^2\\\\a^2 + 12^2 = 13^2\\\\a^2 + 144 = 169\\\\a^2 = 169 - 144\\\\a^2 = 25\\\\a = \sqrt{25}\\\\a = 5[/tex]

The horizontal leg of the largest right triangle is 5 units long.

The identical single tickmarks tell us that the horizontal leg is cut into two smaller pieces of equal length.

Each smaller piece is 5/2 = 2.5 units long.

------------------------------

Now focus on the smaller skinny right triangle with legs a = 2.5, b = 12 and hypotenuse c = x.

Use the pythagorean theorem again to find the hypotenuse x.

[tex]2.5^2 + 12^2 = c^2\\\\6.25 + 144 = x^2\\\\150.25 = x^2\\\\x^2 = 150.25\\\\x = \sqrt{150.25}\\\\x = \sqrt{\frac{601}{4}}\\\\x = \frac{\sqrt{601}}{\sqrt{4}}\\\\x = \frac{\sqrt{601}}{2}\\\\x \approx 12.2577[/tex]

The amount of water that should be mixed with 18 liters of 14% bleach solution to form 10% bleach solution is 7.2 liters.

The amount of water should be mixed with 1 liter of 14% bleach solution,

we know that the water will have 0% bleach. thus, the amount of water we need to mix with the 14% bleach solution is (2/5) liters.

Therefore, the ratio of water and bleach solution can be written as,

[tex]\rm \dfrac{14\%\ solution}{Water} = \dfrac{5}{2}[/tex]

We know the ratio of water and bleach solution that should be mixed to form a 10% concentration bleach is (5/2), therefore, we will use the same ratio,

[tex]\rm \dfrac{14\%\ solution}{Water} = \dfrac{5}{2}[/tex]

[tex]\rm \dfrac{18}{Water} = \dfrac{5}{2}\\\\\rm {Water} = \dfrac{18\times 2}{5}\\\\\rm Water = 7.2\ liters[/tex]

Answer:

PQ = 37 Km

Step-by-step explanation:

let PQ = x , then

PR =  x + 15 and QR = 3(x + 15) = 3x + 45

sum the parts and equate to 245

x + x + 15 + 3x + 45 = 245 , that is

5x + 60 = 245 ( subtract 60 from both sides )

5x = 185 ( divide both sides by 5 )

x = 37

then

PQ = x = 37 Km

  38

Step-by-step explanation:

Sequential pairs will be ...

  17 - 74 or 79

  43 - 38

  74 - 43

  96 - (none)

  87 - 74 or 79

We notice that 17 has no preceding number. It must be first in the list. 79 cannot be second, because that skips a bunch of numbers. The sequence appears to be ...

  17 - 74 - 43 - 38 - 87 - 79 - 96

The 4th number in the list is 38.

Using the mean concept, it is found that the correct option is given as follows:

A

Football Team Mean: 75"

Basketball Team Mean: 77"

Difference: 2"

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

For the football team, considering the 11 players, it is given by:

M = (72 + 80 + 74 + 76 + 76 + 79 + 78 + 73 + 79 + 68 + 70)/11 = 75"

For the basketball team, it is given by:

M = (78 + 79 + 79 + 80 + 76 + 77 + 77 + 76 + 77 + 74 + 74)/11 = 77"

The difference is the subtraction of the means, hence:

D = 77" - 75" = 2"

in this case we will indirectly use this formula. Now we know this; A^2 + 11^2 = 15^2

Let's start using some algebra now B )

A^2 + 121 = 225 > A^2 = 225 - 121 > A^2 = 104 > A = √104

The length of material needed for the border is the perimeter of the backyard play area

The area of the play area is given as:

[tex]Area = 286.56[/tex]

The area of a trapezoid is calculated using:

[tex]Area = 0.5 * (L1 + L2) * H[/tex]

Where L1 and L2, are the parallel sides of the trapezoid and H represents the height.

The given parameter is not enough to solve the length of material needed.

So, we make use of the following assumed values.

Assume that the parallel sides are: 25 feet and 31 feet long, respectively.

While the other sides are 10.2 feet and 8.2 feet

The length of material needed would be the sum of the above lengths.

So, we have:

[tex]Length = 25 + 31 + 10.2 + 8.2[/tex]

[tex]Length = 74.4[/tex]

Using the assumed values, the length of material needed for the border is 74.4 feet
