Find the solution set for the system of equations. 9x + 5y = 28 5x + 9y = 56 the solution set for the system of equations is.

Answers

The solution set for the system of equations is (x, y) = (-2.44, 10.11)

To find the solution set for the system of equations, we can use several methods such as substitution, elimination, or matrix method.

In the elimination method, we try to eliminate one of the variables by adding or subtracting the equations.

One method is to use elimination method:

9x + 5y = 28

5x + 9y = 56

We can eliminate one of the variables by multiplying the first equation by -5 and the second equation by 9:

-45x - 25y = -140

45x + 81y = 504

Adding these two equations together we get:

36y = 364

Solving for y, we get:

y = 364/36 = 10.11

We can then substitute this value back into one of the original equations, for example, the first equation:

9x + 5(10) = 28

9x + 50 = 28

9x = -22

x = -2.44

So, the solution set for the system of equations is (x, y) = (-2.44, 10.11)

Naomi earned $45 after babysitting for 5 hours one afternoon. Another day, she babysat for
8 hours and earned $72. Write two equations (one in point-slope and one in slope-intercept)
that represents the number of hours she babysits, x, and the amount of money she earns, y.

Answers

Leticia babysat 5 hours on Saturday.

How to calculate?

First, we have to look at the equation that models this situation. We learn that the price per hour of babysitting is $8. On Friday, Leticia babysat for 4 hours, and on Saturday, she babysat an unknown amount of time. Leticia watched the children for four hours on Friday and for an undetermined period of time on Saturday.

earned $72, Therefore:

8 ( 4 + x ) = 72

( 4 + x ) = 72 / 8

4 + x = 9

x = 9 - 4

x = 5

Answer:

f(5) = 31/11

f'(5) = 4/11

Step-by-step explanation:

y = 4/11x + 1

f(x) = 4x/11 + 1  ==> y = f(x)

f(5) = 4(5)/11 + 1  ==> substitute 5 for x

f(5) = 20/11 + 1  ==> simplify

f(5) = 20/11 + 11/11  ==> make common denominators to simplify easier

f(5) = (20+11)/11

f(5) = 31/11

f'(x) = 4/11

Hence, f'(5) = 4/11 since every value of x will make the derivative 4/11.

Factorise a³ + b³ + c³ please i need this immediately​

Answers

Answer:

a³(b-c) + b³(c-a) + c³(a-b) = (a-b)(b-c)(c-a) (a + b + c)(a² + b² + c² - ab - bc - ca)

This is a factorized form of the polynomial, as you can see it factorizes as a combination of difference of squares and difference of cubes.

here is one way to factorize the polynomial a³(b-c) + b³(c-a) + c³(a-b) step by step:

First, we can factor out a³ from the first term, b³ from the second term, and c³ from the third term:

a³(b-c) + b³(c-a) + c³(a-b) = a³(b-c) + b³(c-a) + c³(a-b)

Next, we can factor out (b-c) from the first and second terms, and (c-a) from the second and third terms:

a³(b-c) + b³(c-a) + c³(a-b) = (b-c)(a³ + b³) + (c-a)(b³ + c³)

We can factor out (a-b) from the first and third terms, and then we can use difference of cubes to factorise out:

(b-c)(a³ + b³) + (c-a)(b³ + c³) = (b-c)(a-b)(a² + ab + b²) + (c-a)(a-b)(b² + ab + c²)

Now we can combine like terms, and we get:

(b-c)(a-b)(a² + ab + b²) + (c-a)(a-b)(b² + ab + c²) = (a-b)(b-c)(c-a)(a + b + c)(a² + b² + c² - ab - bc - ca)

The factorized form of the polynomial is (a-b)(b-c)(c-a) (a + b + c)(a² + b² + c² - ab - bc - ca)

This is a general formula for the factorization of a polynomial of the form a³(b-c) + b³(c-a) + c³(a-b)

By using difference of cubes we can factorise the above polynomial, hope it helps.

a3 + b3 + c3 = (a+ b+ c ) ( a2 + b2 + c2 – ab – bc – ca ) + 3abc.

4. You are standing at point B. Point B is 21 feet from the center of the circular water storage tank and 19 feet from point A. AB is tangent to ⊙O at A. Find the radius of the tank. (Round answer to one decimal place)

Answers

The radius of the tank is 28.3 feet (rounded to one decimal place).

What is radius?

Radius is a term used to describe the distance from the center of a circle to any point on the circumference. It is a line segment that runs from the center of the circle outwards, perpendicular to the circumference. The radius of a circle is the same for all points on the circumference, and it is always half of the diameter.

The radius of the tank can be determined using the Pythagorean Theorem. Since we are given the distances from the center of the tank (O) to points A and B, we can use the following formula to calculate the radius:

R = √(OA² + OB²).

Plugging in the given values, we get:

R = √(21² + 19²) = √(441 + 361) = √802 = 28.29

Therefore, the radius of the tank is 28.3 feet (rounded to one decimal place).

Answers

Step-by-step explanation:

Firstly you have to open brackets

4b(5a - 2) = 2c

20ab - 8b = 2c

20ab = 2c + 8b

Divide both sides by 20b(coefficient of a)

a = (2c + 8b)/20b

Answer:

[tex]a = \dfrac{2}{5} + \dfrac{c}{10b}[/tex]

Step-by-step explanation:

Expand 4b(5a-2) on the left side

4b(5a-2)  = 4b · 5a -4b · (-2)

= 20ab -8b

Therefore we get

20ab -8b = 2c

Add 8b on both sides to get rid of the -8b on the left

20ab - 8b + 8b = 2c + 8b

20ab = 8b + 2c

Divide by 20 both sides:
20ab/20 = 8b/20 + 2c/20

ab = (2/5)b + c/10

Divide by b both sides

==> ab/b = (2/5)b/b + c/10b

==> a = 2/5 + c/10b

What height represents the 85th percentile?
What height represents the first quartile?

Answers

The height that represents the 85th percentile is 66.8 inches.

The height that represents the first quartile is 62.4 inches.

What height represents the 85th percentile?

Generally, To find the height that represents the 85th percentile, you would need to use a z-score table or calculator.

The z-score represents the number of standard deviations away from the mean of a particular value.

For the 85th percentile, the z-score would be 1.04. To find the height, you would use the formula:

(z-score) * (standard deviation) + mean

So, in this case:

1.04 * 2.8 + 63.7 = 66.612 inches

b) To find the height that represents the first quartile (25th percentile), you would use the same process but with a z-score of -0.67.

-0.67 * 2.8 + 63.7 = 61.824

The base of a right triangle is 48cm and its hypotenuse is 50cm. What will be the areas of the triangle? class 9​

Answers

The area of a triangle can be found using the formula:

Area = (1/2) * base * height

In this case, the base of the triangle is 48cm and the hypotenuse is 50cm. Since this is a right triangle, we can use the Pythagorean theorem to find the length of the height. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. So,

c^2 = a^2 + b^2

50^2 = 48^2 + b^2

2500 = 2304 + b^2

b^2 = 2500 - 2304

b = √(2500 - 2304)

b = √(196)
