Answer:

x(3y - 1) and (2a - 3)(2a + 3)

Step-by-step explanation:

(1)

3xy - x ← factor out x from each term

= x(3y - 1)

(2)

4a² - 9 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

4a² - 9

= (2a)² - 3²

= (2a - 3)(2a + 3)

Answer:

Part 1 is the 16 square feet

Part 2 is the 128 cube feet

Answer:

4067

Step-by-step explanation:

Box 1

x - y = 4

x - 0 = 4

x = 4

Box 2

x = 4

y = 0

(x, y) => (4, 0)

Box 3

x - y = 4

-1 - y = 4

-y = 4 + 1

y = -5

Box 4

x = 0

y = -4

(x, y) => (0, -4)

Answer:

The Fourth one

[tex]f(x) = {5}^{x} [/tex]

Step-by-step explanation:

I hope that is useful for you :)

For Number one: -xy + 2x = 20, x = 5

To solve this, all we need to do is plugin 5 for every place we have x. So...

- (5)y + 2(5) = 20

-5y + 10 = 20

-5y = 10

y = -2

For number two: 4x - 3y - 10 = 1, x = -1

To solve this, we need to plugin -1 for all of the x variables. So...

4 (-1) - 3y - 10 = 1

-4 - 3y - 10 = 1

-14 - 3y = 1

-3y = 15

y = -5

For number three: 5x + 7y = -1, x = 4

We need to plugin -4 for all of the x variables. So...

5 (4) + 7y = -1

20 + 7y = -1

7y = -21

y = -3

For number four: x = 6 + xy, x = -3

Same as the other ones, just plugin -3 for all of the x variables. So...

-3 = 6 + (-3)y

-3 = 6 - 3y

-9 = -3y

3 = y

I hope this helps :)

Answer:

x = 12 cm

Step-by-step explanation:

Based on the tangent and secant theorem,

8² = 4(4 + x)

Solve for x

64 = 16 + 4x

Subtract 16 from both sides

64 - 16 = 4x

48 = 4x

Divide both sides by 4

48/4 = 4x/4

12 = x

x = 12

The scatter plot is solved a graph has year on the x-axis, and contribution on the y-axis, from 50,000 to 500,000. Points are at (1, 70,000), (3, 150,000), (5, 190,000), (8, 230,000), (11, 270,000), (14, 290,000).

Dots are used in a scatter plot to show the values of two different numerical variables. Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.

The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger the relationship. If the data points make a straight line going from near the origin out to high y-values, the variables are said to have a positive correlation.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

Given data ,

Let the scatter plot represents the funds raised by a TV station since its first year of operations

Let the number of years be represented as x

Let the contribution be represented as y

where the values of x and y are

x = { 1 , 3 , 5 , 8 , 11 , 14 }

y = { 70000 , 150000 , 190000 , 230000 , 270000 , 290000 }

The scatter plot is graphed and the linear regression equation is

y = 15901.6x + 88688.5

Hence , the scatter plot for the contribution for x years is plotted

Answer:

The measure of m∠KNY is;

(D) 105°

Step-by-step explanation:

From the diagram, we have;

The given angle at the circumference = The The angle the arcs makes at the center of the circle

From circle, theorem, angle subtended at the center = Twice the angle subtended at the circumference

Therefore;

Angle ∠D and angle ∠Y = 90°/2 = 45°

Angle ∠O and angle ∠K = 60°/2 = 30°

From angle summation theorem, we have;

m∠KNY + ∠K + ∠Y = 180° (The sum of the interion angles in ΔYNK

∴ m∠KNY = 180° - (∠K + ∠Y)

Plugging in the known values of ∠K and ∠Y gives;

m∠KNY = 180° - (30° + 45°) = 105°

m∠KNY = 105°.
