The point divides the line in the respective ratios. The correct matches are done.

When a point lies on the line such that is gets divided into the ratio is said to be the division of line.

The coordinates of point can be find out by the following formula.

x = mx₂ +nx₁ / m+n   and y = my₂ +ny₁ / m+n

For, Point C(-3.6, -3.4) divides in the ratio 2 : 3.

Substituting the values, we get

-3.6 =  2x₂ +3x₁ / 2+3                 and           -3.4 = 2y₂ +3y₁ / 2+3

 2x₂ +3x₁ = -18                           and               2y₂ +3y₁ = -17

The above equations are satisfied by the points A(-2,-1) and B (-6,-7)

For, Point C(4, 1.6) divides in the ratio 3 : 2.

Substituting the values, we get

4 =  3x₂ +2x₁ / 2+3                     and           1.6 = 3y₂ +2y₁ / 2+3

3x₂ +2x₁ = 20                          and               3y₂ +2y₁ = 8

The above equations are not satisfied by any of the points.

For, Point C(3.5, -2.5) divides in the ratio 1 : 7.

Substituting the values, we get

3.5 =  1x₂ +7x₁ / 1+7                     and           1.6 = y₂ +7y₁ /1+7  

x₂ +7x₁ = 28                          and                y₂ +7y₁ = -20

The above equations are not satisfied by any of the points.

For, Point C(8, 9) divides in the ratio 5 : 3.

Substituting the values, we get

8 =  5x₂ +3x₁ /5+3                    and           9 = 5y₂ +3y₁ /5+3  

 5x₂ +3x₁ =64                          and                5y₂ +3y₁ = 72

The above equations are satisfied by the points A (3,4) and B(11, 12).

For, Point C(-2, 5) divides in the ratio 2 : 6.

Substituting the values, we get

-2 =  2x₂ +6x₁ /2+6                    and           5 = 2y₂ +6y₁ /2+6  

 2x₂ +6x₁  =-16                          and                2y₂ +6y₁ = 40

The above equations are satisfied by the points A (-5,2) and B(7,14).

For, Point C(0,1) divides in the ratio 4 : 7.

Substituting the values, we get

0 =  4x₂ +7x₁ /4+7                   and           1= 4y₂ +7y₁ /4+7  

 4x₂ +7x₁  = 0                      and                4y₂ +7y₁ = 11

The above equations are satisfied by the points A (4,-3) and B(-7,8).

Thus, all the equations are joined with their satisfying points.

To solve the negative exponents , we have to apply the negative exponent rule or the fractional exponent rule.

To calculate the negative exponent we need to remember about the negative exponent that the base is on the opposite side of the fraction. Here , We need to flip the fraction so that the base will be on the other side.

Negative exponent Rule :-

[tex]a^{-n} = \frac{1}{a^{n} }[/tex]

Now , we will solve a fraction with negative exponent

For example ; Simplify the fraction [tex]\frac{3^{-2} }{9^{-2} }[/tex]

Solution : [tex]\frac{3^{-2} }{9^{-2} } = \frac{9^{2} }{3^{2} }= \frac{81}{9}[/tex]

= 9

Here, 9 is the answer of the above example.

From the Brainly link attached, we can see the diagram and we can say that;

We are given a right angled triangle with;

A known angle of; θ = 20°

Length of the hypotenuse = 80

Now, we want to find the length of the base x. Thus, we will use trigonometric ratio to get;

cos θ = x/hypotenuse

Thus;

The equation of the tangent to the curve at the point corresponding to the given value of the parameter will be x + y = c.

The curves are given below.

x = t⁵ + 1 and y = t⁶ + t

Then differentiate the functions with respect to t, then we have

[tex]\rm \dfrac{dx}{dt} = 5t^4\\[/tex]   ...1

and

[tex]\rm \dfrac{dy}{dt} = 6t^5 + 1[/tex]   ...2

Divide equation 2 by equation 1, then we have

[tex]\rm \dfrac{\dfrac{dy}{dt} }{\dfrac{dx}{dt} } = \dfrac{dy}{dx} = \dfrac{6t^5 + 1}{5t^4}[/tex]

Then the slope of the equation at t = −1, then we have

dy/dx = [6(-1)⁵ + 1]/[5(-1)⁴]

dy/dx = (-6+1)/5

dy/dx = -5/5

dy/dx = -1

Then the equation of the tangent line will be

y = -x + c

x + y = c

Where c is a constant.

By counting the total number of outcomes, we conclude that the spinner has 4 sections.

Let's say that the spinner has N sections.

If we spin it twice, for the first outcome we have N possible outcomes and for the second spin there are N possible outcomes.

Then for the experiment of spinning the spinner twice, the number of outcomes is:

O = N*N

And we know that the number of possible outcomes for spinning the spinner twice is 16, then we have:

16 = N*N = N^2

Solving for N, we have:

N = √16 = 4

Then we conclude that the spinner has 4 sections.

Analysis:

50 (total) = x + 1/4 + 5/8 than solve for x

how much money leftover (x)

= total - spent on gif card - spent on new wallet

x = 50 - 1 / 4 - 5 / 8

Solution:

x = 50 - 1/4 - 5/8

x = 50 - 12.5 - 5/8

x = 50 - 12.5 - 31.25

x = 6.25

Statement:

We found that the leftover amount is $6.25.

Therefore, the leftover amount of money with a starting amount of $50.00 and purchasing a gift card and new wallet is in fact $6.25.

Answer:

y-2x-2

Step-by-step explanation:

The way I would do this is by first using the information given and making an equation in point-slope form, before bringing it to y=mx+b.

We know that the slope is -2, and we have a point, (2,-6). The formula for equations in point slope form is [tex]y-y_{1} =m(x-x_{1} )[/tex]. So, we can insert the given information into this formula to get [tex]y+6=-2(x-2)[/tex].

Next, we distribute the slope to the the parenthesis to get [tex]y+6=-2x+4[/tex]

Then, we subtract 6 from both sides to get [tex]y=-2x-2[/tex]

Since this equation is now in the form [tex]y=mx+b[/tex], the answer is [tex]y-2x-2[/tex]
