Answer:

y = -15/8x - 35/8

Step-by-step explanation:

Find the slope = [tex]\frac{change in y}{change in x}[/tex]

                         = [tex]\frac{80 - 5}{-45 - (-5}[/tex])

                         =  [tex]\frac{75}{-40}[/tex]

                         =   [tex]\frac{-15}{8}[/tex]

Find the y-intercept    Use one point (-5, 5) and the slope  [tex]\frac{-15}{8}[/tex]

 y = mx + b

 5 =  -15/8 (-5) + b

  5 = 75/8 + b

  5 - 75/8 = b

   -35/8 = b

Write the equation  

         y = -15/8x - 35/8

Answer:

[tex] \frac{7}{72} [/tex]

Step-by-step explanation:

The question is :

[tex] \frac{1}{9} \div \frac{8}{7} [/tex]

We need to take the reciprocal which means invert the :

[tex] \frac{8}{7} [/tex]

So, it will be :

[tex] \frac{1}{9} \times \frac{7}{8} [/tex]

After that , do 1 × 7 on numerator and 9 × 8 on denominator....

After multiplication you'll get :

[tex] \frac{7}{72} [/tex]

1/9 divided by 8/7 is equal to 7/72.

To divide fractions, you can use the following rule: invert the second fraction and multiply it by the first fraction.

In this case, you have:

1/9 ÷ 8/7

To divide, we invert the second fraction:

1/9 × 7/8

Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:

(1 × 7) / (9 × 8)

This simplifies to:

7/72

Therefore, 1/9 divided by 8/7 is equal to 7/72.

Answer:

A=πr2

Step-by-step explanation:

Area of a circle is found by the following formula-

Area of Circle = πr^2

Where -

π = pie, value of 3.14 or 22/7

r = radius of a circle

Example -

A circle has a radius of 10 cm. Find the area of the circle.

Solution -

Area of Circle = A=πr^2

A = 3.14*10^2

A= 314 cm

Note - Most preferably, 3.14 is the most common value used for pie. You can also use 22/7, and would end up with roughly the same answer, but it takes more time to solve with a fraction like 22/7.

Answer:

y = 3/2x + 6

Step-by-step explanation:

1. Add 3x to both sides (2y=3x+12)

2. Divide both sides by 2 to isolate the y (y=3/2+6)

The area of a shape is the amount of space it occupies.

The largest garden you could make is 49 square meters

The perimeter is given as:

[tex]\mathbf{Perimeter = 28}[/tex]

This is calculated as:

[tex]\mathbf{2 \times (Length + Width) = 28}[/tex]

Divide by 2

[tex]\mathbf{Length + Width = 14}[/tex]

This means that, the sum of the dimensions must equal 14.

So, the possible dimensions are:

The garden with the largest dimension is: 7 by 7 meters.

So, the area of garden is:

[tex]\mathbf{Area = 7m \times 7m}[/tex]

[tex]\mathbf{Area = 49m^2}[/tex]

The largest garden you could make is 49 square meters

Answer:

4. B

5. D

Step-by-step explanation:

4. Draw a line at angle to the line segment JK.

Then make three arcs on the new line using a compass without changing the setting.

Join the last arc to the endpoint of the line segment (in this case, K) and draw two parallel lines originating from the other two arcs.

5. Recall, there are two lines a and b

where x is the geometric mean.

Draw a line.

Label a point on the line (say, R)

Construct a segment (or arc) with endpoint R and length "a".

Construct a segment (or arc) with length "b" adjacent to the previous segment.

Label the endpoints (say, S and T). The line segment from point RS is "a" and that from point ST is "b".

Construct the perpendicular bisected of segment RT.

Label the midpoint of segment RT.

Using the midpoint as the center and half the length of RT as the radius, construct a semicircle.

At S, construct the perpendicular to segment RT. Label the intersection between the semicircle and perpendicular (say, Y)

SY is the geometric mean.

a/x = x/b is RS/SY = SY/ST

Answer:

  3 times

Step-by-step explanation:

We observe that both functions are vertically scaled versions of the parent quadratic y = x^2. The ratio of scale factors is 2.7/0.9 = 3. That is, ...

  g(x) = 3f(x)

This means that whatever vertical difference f(x) may show over the interval, g(x) will show 3 times that difference.

The average rate of change of g(x) is 3 times that of f(x).

What is Number system?

A system of writing to express the number is called number system.

Given that;

The expression is;

''800 is 5 1/4% of number''

Now,

Let a number = x

Then, Expression is written as;

800 = 5 1/4% of x

800 = 21/4% × x

800 = 21/400 × x

x = 800 × 400 / 21

x = 15,238.1

Thus, The number is 15,238.1.

Find 100 on cumulative frequency and the correspinding time: 14 minutes. So the answer is 14 minutes.

(ii)

First, find the lower quartile —> 200/4 = 50

Upper quartile —> 200/(3/4) = 150

Find the difference: 150 - 50 = 100
