Answer:

Option A. – 3

Step-by-step explanation:

From the question given above, the following data were obtained:

y = 3/4

xy² = 9/16

(x – 4) =?

Next, we shall determine the value of x. This can be obtained as follow:

y = 3/4

xy² = 9/16

x(3/4)² = 9/16

x (9/16) = 9/16

Divide both side by 9/16

x = 9/16 ÷ 9/16

x = 1

Finally, we shall determine the value (x – 4). This can be obtained as follow:

(x – 4)

x = 1

(x – 4) = 1 – 4

= – 3

Answer:

Step-by-step explanation:

This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.

If you have a triangle that hast angles of 100 50 and 30

The largest side will be opposite the 100 degree angle.

The smallest side will be opposite the 30 degree angle.

So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.

So the answer is Since 43 > 40 then CD>AB

Step-by-step explanation:

Answer:

TZ = 10 units

UY = 12 units

ZW = 11 units

Step-by-step explanation:

Point Z is the centroid of ΔTUV.

Since, centroid of a triangle is located on each median so that it divides each median in the ratio of 2 : 1

Therefore, TZ = 2(ZX)

TZ = 2(5) = 10 units

UY = UZ + ZY

     = UZ + [tex]\frac{1}{2}(UZ)[/tex]

     = [tex]\frac{3}{2}UZ[/tex]

     = [tex]\frac{3}{2}\times 8[/tex]

     = 12 units

ZW = [tex]\frac{1}{3}(VW)[/tex]

      = [tex]\frac{1}{3}(33)[/tex]

      = 11 units

Given:

The increase in pressure P is the linear function of the depth d.

[tex]P(d)=0.445d+14.7[/tex]

The cost of dinner is $300 and $10 per students.

To find:

The initial value and rate of change and their interpretation.

Find the cost function C where n is the number of students.

Solution:

The slope intercept form of a linear function is

[tex]f(x)=mx+b[/tex]          ...(i)

where, m is rate of change and b is y-intercept or initial value.

We have,

[tex]P(d)=0.445d+14.7[/tex]        ...(ii)

From (i) and (ii), we get

[tex]m=0.445,b=14.7[/tex]

The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.

Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.

The cost of dinner is $300 and $10 per students.

Let C(n) be the total cost for dinner and n be the number of students.

Fixed cost = $300

Additional cost for 1 student = $10

Additional cost for n student = $10n

Now,

Total cost = Fixed cost + Additional cost

[tex]C(n)=300+10n[/tex]

Therefore, the required cost function is [tex]C(n)=300+10n[/tex].

im stuck on the same problem

The measure of QR, from the triangle TRQ is 16 units.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, triangle PML is similar to triangle TRQ.

From the given triangles.

ML/QR =PM/TR

(7x-9)/(2x+2) = 35/14

(7x-9)/(2x+2) = 5/2

2(7x-9)=5(2x+2)

14x-18=10x+10

4x=28

x=7

Then, QR=2x+2=16 units

Therefore, the measure of QR is 16 units.

Answer:

(-2, -4)

Step-by-step explanation:

Since both equations are equal to y, you can set them equal to each other:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]

Next, solve for x:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]

Finally, substitute the solution for x in one of the equations (or both) to find y:

[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]

[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]

Therefore, the solution to the system of equations is (-2, -4).

Answer:

Step-by-step explanation:

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

Changing to slope-intercept form:

2x - 3y = 9         {subtract 2x from both sides}

-3y = -2x + 9        {divide both sides by (-3)}

y = ²/₃x - 3     ⇒    m₁=²/₃   ⇒   m₂=²/₃

The line y=²/₃x+b passes through point (6, 7) so the equation:

7 = ²/₃×6 + b  is true

7 = 4 + b

b = 3

Therefore equation in  slope-intercept form:

                                                     y = ²/₃x + 3

The equation of the line passing through the point (6, 7) parallel to the line is y = 2/3x + 3

The equation in slope - intercept form :

2x - 3y = 9

-3y = 9 - 2x

Divide both sides by - 3

y = - 3 + 2/3x

Using the points (6, 7)

7 = c + 2/3(6)

7 = c + 12/3

7 = c + 4

c = 7 - 4 = 3

c = 3

The equation of the parallel line is thus :

Answer: 56

Step-by-step explanation:

Mean allowance of the given students is equals to $13.

" Mean is defined as the ratio of the sum of all the given number to the  total number of numbers. It is also known as average."

Formula used

Mean = [tex]\frac{Sum of all the given numbers}{Total number of numbers}[/tex]

According to the question,

Number of students = 10

Weekly allowances of each student

= $9, $11, $13, $15, $20, $10, $12, $15, $10, $15

Substitute the value in the formula of mean we get,

mean = [tex]\frac{9+11+12+13+20+2(10)+3(15)}{10}[/tex]

         [tex]= \frac{130}{10}\\ \\= 13 dollars[/tex]

Answer:

y- intercept = - 2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)

m = [tex]\frac{-25+7}{5-1}[/tex] = [tex]\frac{-18}{4}[/tex] = - 4.5 , then

y = - 4.5x + c

To find c substitute either of the 2 points into the equation

Using (1, - 7), then

- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5

y- intercept c = - 2.5

He spent rs.150  for stitching a shirt

total cots= 950+150

total cost=1100

gain= rs.375

we know that
