Answer:

The constant of proportionality is [tex]k=\frac{7}{9}[/tex]

Step-by-step explanation:

Recall that the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality.

Here, [tex]k=\frac{7}{9}[/tex] since [tex]2(\frac{7}{9})=\frac{14}{9}=1\frac{5}{9}[/tex], [tex]3(\frac{7}{9})=\frac{21}{9}=2\frac{3}{9}[/tex], and so on.

Answer: x = -8

Step-by-step explanation:

Move all terms that don't contain x to the right side and then solve

180 = 132 + x + x

180 - 132 = 2x

48 = 2x

x = 24⁰

[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]

Let's use Angle sum property of a triangle ~

[tex]\qquad \sf  \dashrightarrow \: x + x + 132 \degree = 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x + 132 \degree = 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x = 180 \degree - 132 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x = 48 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 48 \degree \div 2[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 24 \degree[/tex]

Answer:

a) Rectangle:

Length = 12 cm

Breadth = 6 cm

Area = length × breadth

= 12 × 6

= 72 cm²

b) Triangle A:

Base = 3 cm

Height = 6 cm

Area = 1/2 × base × height

= 1/2 × 3 × 6

= 9 cm²

c) Triangle B:

Base = 3 cm

Height = 6 cm

Area = 1/2 × base × height

= 1/2 × 3 × 6

= 9 cm²

d) Parallelogram:

Base = (12 - 3) = 9 cm

Height (distance between two parallel sides – the ones you use as your base) = 6 cm

Area = base × height

= 9 × 6

= 54 cm²

Answer:

y=2x+5

Step-by-step explanation:

The slope-intercept form of a linear equation is:

y=mx+b

Where m is the slope and b is the y-intercept.

We can start by finding the slope...

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can use any two x, y pairs to solve for the slope. In this case let's use (0,5) and (2,9)...

[tex]Slope=\frac{9-5}{2-0}=\frac{4}{2}=2[/tex]

The y-intercept is where the line intersects the y-axis. This means that the x value is 0. In the table we can see when the x value is 0, the y value is 5 meaning the y-intercept is 5...

y=2x+5

Answer:

dimensions: 8 ft x 8 ft      ║       32 ft of  fence she used.

Step-by-step explanation:

as its a square, its formula for area: length²

using the formula:

length² = 64

length = √64

length = 8 ft

→ The dimensions of the kennel is 8 ft x 8 ft

Using the length, we can find; how many fencing she used:

formula used: 2 ( length + length )

using the formula:

2 ( 8 + 8 )

2 ( 16 )

32 ft

Answer:

4k - 8

Step-by-step explanation:

Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.

Hope this helps!

Answer:

Note: Any number or variable(unknown) raised to the index or power zero (0)* is equal to one (1)*.

3. Solution

Given: x = 2 and y = 5

-4x^-2 + 3y^0

by substituting the values of x and y,

> -4(2)^-2 + 3(5)^0

> -4/(2)^2 + 3(5)^0

> -4/4 + 3(1)*

> -1 + 3 = 2

4. Solution

Given: x = 2 and y = 5

2x^0y^-2

by substituting the values of x and y

> 2(2)^0(5)^-2

>2(2)^0×1/(5)^2

>2(1)×1/25

>2×1/25

Answer:

37.5%

Step-by-step explanation:

let 15 is X % of 40,

now,

x% of 40 =15

or,X/100 ×40 =15

or,X=(15×100)/40

or,X=1500/40

orX=37.5%
