Step-by-step explanation:

Man this one is a world of its own :D Just a quick question are you a fellow Add Math student in O levels i remember this question from back in the day :D Anyhow Lets get started

For this question we need to know the following identities:

[tex]1+tan^{2}x=sec^2x\\\\1+cot^2x=cosec^2x\\\\sin^2x+cos^2x=1[/tex]

Lets solve the bottom most part first:

[tex]1-\frac{1}{1-sec^2x} \\\\[/tex]

Take LCM

[tex]1-\frac{1}{1-sec^2x} \\\\\frac{1-sec^2x-1}{1-sec^2x} \\\\\frac{-sec^2x}{1-sec^2x} \\\\\frac{-(1+tan^2x)}{-tan^2x}[/tex]

now break the LCM

[tex]\frac{-1}{-tan^2x}+\frac{-tan^2x}{-tan^2x}\\\\\frac{1}{tan^2x}+1\\\\cot^2x+1[/tex]

because 1/tan = cot x

and furthermore,

[tex]cot^2x+1\\cosec^2x[/tex]

now we solve the above part and replace the bottom most part that we solved with [tex]cosec^2x[/tex]

[tex]\frac{1}{1-\frac{1}{cosec^2x} } \\\\\frac{1}{1-sin^2x} \\\\\frac{1}{cos^2x}\\\\sec^2x[/tex]

Hence proved! :D

Answer:

subtracting one from the other

Step-by-step explanation:

The equations are not well written. Let us assume the equations are:

2x + y = 7 .... 1

2x + 2y = 5 ....2

Looking at the two equations, using elimination method will be the best way to go.

Since the coefficient of the variable x are the same, we can take the difference of both equation to cancel out the variable x and get y as shown;

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

0 - y = 2

y = -2

Note that you can only subtract if the coefficient of the variables in both equations have the same coefficient (same sign) and add if they have different signs

Answer:

y = 1/2x - 7.5

Step-by-step explanation:

The image below shows proof that the equation y = 1/2x - 7.5 is the line that contains the point (3,-6) and has the slope of 1/2.

Answer:

The blob will grow 215 kg in 2 weeks.

Step-by-step explanation:

As an alien blob started with a mass of 19 kg and is doubling in size every day.

Thus, we can use the equation

where x is the number of days and y is the mass size of the alien blob

as

so plugin x = 14 to determine the size of the blob after two weeks

Thus,

y = x² + 19

y = (14)² + 19

y = 215 kg

Thus, the blob will grow 215 kg in 2 weeks.

Answer:

5/2

Step-by-step

Formula for slope is y2-y1/x2-x1

so it would be 13-3/5-1

which results to 10/4

simplify 5/2

The required slope for the line is m = 5/2.

Two pairs of coordinates are given the slope of the line that passes through points to determine.

The slope of the line is the tangent angle made by the line with horizontal. i.e. m =tanx where x in degrees.

The slope of a line (m) =[tex]y_2-y_1/x_2-x_1[/tex]
   [tex](x_1, y_1), (x_2,y_2) = (1,3),(5,13)[/tex]
m = 13-3/5-1
m = 10/4
m =5/2

Thus, the required slope for the line is m = 5/2.

Answer:

Thanks

Step-by-step explanation:

Given:

The graph of system of inequalities.

To find:

The inequalities.

Solution:

From the given graph it is clear that dotted line is a vertical line parallel to the x-axis and one unit above the x-axis. So, the equation of dotted line is

[tex]y=1[/tex]

The area below the dotted line is shaded. It means, y values must be less than 1. So, the required inequality for dotted line is

[tex]y<1[/tex]         ...(i)

Solid line passes through (-5,-5), (0,0) and (5,5). It means y is directly proportional to x with 1 as constant of proportionality. So, the equation of solid line is

[tex]y=x[/tex]

The area above the solid line is shaded. It means, y values must be greater than or equal to x. So, the required inequality for solid line is

[tex]y\geq x[/tex]      ...(ii)

So, the system of inequalities have inequalities [tex]y<1[/tex] and [tex]y\geq x[/tex].

Therefore, the correct option is D.

Answer:

6/10

Step-by-step explanation:

The fraction 6 / 10 shows the ratio of 3 dogs to 5 dogs is the same. Then the correct option is A.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

The ratio of 3 dogs to 5 dogs will be given as,

Ratio = 3 / 5 = 0.60

Let's check all the options, then we have

A)  6 / 10, then the ratio is given as,

Ratio = 6 / 10 = 0.60

B)  27 / 40, then the ratio is given as,

Ratio = 27 / 40 = 0.675

C)  9 / 10, then the ratio is given as,

Ratio = 9 / 10 = 0.90

D)  12 / 15, then the ratio is given as,

Ratio = 12 / 15 = 0.80

The fraction 6 / 10 shows the ratio of 3 dogs to 5 dogs is the same. Then the correct option is A.

Answer:

idrk what you're asking here but I tried to solve it. fifteen is six more than a number=9

2/5 of a number is 20= 50(?)

thirty is seven less than twice a number= 74

Step-by-step explanation:

for the first one I subtracted 6 from 15 and got 9.

for the second one I was a little confused but I thought that because 2/5 was 20 than 1/5 would be 10. so I just counted 10,20,30,40,50. then I put 50/5 and simplified it to get 10/1 (further simplified as 10).

for the third one I wrote out the problem:

x2

-7

____

30

and I did everything back wards.

30+7= 37

37×2=74
