Answer:

k = 3

Step-by-step explanation:

If the line passing through the points A (-1,3k) and B (k , 3) is parallel to the line whose equation is 2y+3x=9, then their slopes are equal

For coordinate AB;

slope m1 = 3 - 3k/k-(-1)

m1 = 3-3k/k+1

For the line 2y+3x = 9

2y = -3x + 9

y = -3/2 x + 9/2

Slope m2 = -3/2

Since m1 = m2

3-3k/k+1 = -3/2

Cross multiply

2(3-3k) = -3(k+1)

Expand

6 - 6k = -3k - 3

-6k+3k = -3 - 6

-3k = -9

k = -9/-3

k = 3

Hence the value of k is 3

Step-by-step explanation:

1. Arrange your number in numerical order

2. count how many numbers you have

3. if you have an odd number round divide by 2 and round up to gry the position of the median nunber.

4. if you have an even number divided by 2 go to the number in that position and average it with the number in the next higher position to get the median.

Answer:

12[tex]x^{5}[/tex] + x³ + 6x² - 35x - 10

Step-by-step explanation:

(3x² - 5)(4x³ + 7x + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(4x³ + 7x + 2) - 5(4x³ + 7x + 2) ← distribute parenthesis

= 12[tex]x^{5}[/tex] + 21x³ + 6x² - 20x³ - 35x - 10 ← collect like terms

= 12[tex]x^{5}[/tex] + x³ + 6x² - 35x - 10

Answer: 0.75

Step-by-step explanation:

Cos A = 0.8 = 4/5

Note that:

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = opposite / adjacent

Since cos = adjacent / hypotenuse

Therefore, we need to find the opposite which will be:

Hypothenuse² = Opposite² + Adjacent²

5² = Opposite² + 4²

Opposite² = 5² - 4²

Opposite² = 25 - 16

Opposite² = 9

Opposite = ✓9

Opposite = 3

Since tangent = opposite / adjacent

Tan a = 3/4 = 0.75

Answer:

Step-by-step explanation:

× A = 4y + 2 = 2(4y/2 + 2/2) = 2(2y + 1) ≠ 4(y + 2)

✓ B = 4y + 8 = 4(4y/4 + 8/4) = 4(y + 2) = 4(y + 2)

× C = y + y + y + y + 2 =

y (1 + 1 + 1 + 1) + 2 = 4y + 2 = A ≠ 4(y + 2)

✓ D = 5(y + 2) – (y + 2) = 5(y + 2) – 1(y + 2) =

(5 – 1)(y + 2) = 4(y + 2)

✓ E = y + y + y + y + 2 + 2 + 2 + 2 =

y (1 + 1 + 1 + 1) + (2 + 2 + 2 + 2) =

4y + 8 = B = 4(y + 2)

× F = 5(y + 2) – (y – 2) =

(5y + 10) + (-y + 2) =

(5y – y) + (10 + 2) =

4y + 12 = 4(y + 3) ≠ 4(y + 2)

Answer:

10.2

Step-by-step explanation:

20x=204

x=10.2

Answer:

x = 10.2

Step-by-step explanation:

To solve for x, we have to isolate it on one side of the = sign. The number on the other side is the value of x.

20x - 4 = 200

First, we can remove -4 from the equation. The inverse of -4 is +4, so we will add 4 to both sides. Adding 4 to -4 will neutralize it, making its value 0.

20x - 4 + 4 = 200 +4

Simplify this.

20x = 204

Now, we have 20 · x = 204. The inverse of multiplication is division. To the times 20, we will divide by 20 as well.

[tex]\frac{20x}{20}[/tex] = [tex]\frac{204}{20}[/tex]

Simplify.

x = 10.2

We can check this by substituting the value of x, 10.2, for the variable.

20(10.2) - 4 = 200

204 - 4 = 200

200 = 200

Since the equation is true, the answer must be 10.2.

Park is located at point (-5,4).

Paula's house is halfway between the Grocery store and park.

School is halfway between the Paula's house and park.

To find:

Ordered pair for the school.

Solution:

Formula used:

[tex]\text{Midpoint}=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Paula's house is halfway between the Grocery store and park. It means the location of Paula's house is the midpoint of (5,-4) and (-5,4).

[tex]\text{Paula's house}=\left(\dfrac{5+(-5)}{2},\dfrac{(-4)+4}{2}\right)[/tex]

[tex]\text{Paula's house}=\left(\dfrac{0}{2},\dfrac{0}{2}\right)[/tex]

The ladder will reach 43.9 feet of the house.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given that, the height of the ladder is 50 feet and it reaches 48 feet of the house.

Note that the ladder the base and the side wall together make a right triangle whose hypotenuse is the ladder itself.

Therefore, the base of the right triangle is given by:
b² = 50² - 48²

b² = 196

b = 14

Now, the base is dragged by 10 feet, so the base of the new triangle is:
bₙ = 14 + 10

bₙ = 24

The height of the new triangle is:
hₙ = √(50² - 24²)

hₙ = √1924

hₙ = 43.9

Hence, the ladder will reach 43.9 feet of the house.
