Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply the coordinates of the point by the scale factor, that is

R(- 2, 3 ) → R'([tex]\frac{1}{3}[/tex](- 2), [tex]\frac{1}{3}[/tex](3) ) → R'( - [tex]\frac{2}{3}[/tex], 1 ) → C

Answer:

Solving Inequalities is very similar to solving Equations.

If you multiply or divide one side of an equation or inequality by the same number, you have to multiply or divide the other side of the equation or inequality by the same number.

The difference between solving equations and solving inequalities is:  If you multiply or divide an inequality by a negative number, then the inequality reverses.

The comparison between inequalities and equation written down below.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other.

To solve the inequality,

you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

To solve an equation,

Remove parentheses and combine like terms to simplify each side of the equation. To isolate the variable term on one side of the equation, use addition or subtraction. To find the variable, use multiplication or division.

Hence, the process of solving equations and inequalities.

Answer:

(2,-11) is the vertex

Answer:

Step-by-step explanation:

[tex]f(x)=3x^2-12x+1\\\\f(x)=3(x^2-4x)+1\\\\f(x)=3(x^2-2\cdot x\cdot2+2^2-2^2)+1\\\\f(x)=3(\underline{x^2-4x+4}-4)+1\\\\f(x)=3[(x-2)^2-4]+1\\\\f(x)=3(x-2)^2-12+1\\\\f(x)=3(x-2)^2-11[/tex]

the vertex form of parabola's equation is: f(x) = a(x - h)² + k with vertex (h,k)

x-h = x-2  ⇒  h = 2

+k = -11    ⇒   k = 11

Answer:

yes

Step-by-step explanation:

By the converse of Pythagoras' identity.

If the longest side squared is equal to the sum of the squares of the other 2 sides, then the triangle is right.

longest side = 50.5

50.5² = 2550.25

10² + 49.5² = 100 + 2450.25 = 2550.25

Thus the given triangle is right.

trust me i got it right copy link to my work

Answer:

D

Step-by-step explanation:

Δ CED and Δ CAB are similar thus the ratios of corresponding sides are equal, that is

[tex]\frac{CE}{CA}[/tex] = [tex]\frac{ED}{AB}[/tex] , substitute values

[tex]\frac{x}{156-x}[/tex] = [tex]\frac{7}{84}[/tex] = [tex]\frac{1}{12}[/tex] ( cross- multiply )

12x = 156 - x ( add x to both sides )

13x = 156 ( divide both sides by 13 )

x = 12

Thus

AC = 156 - x = 156 - 12 = 144 → D

Answer:

D.  144

Step-by-step explanation:

Triangle BAC is similar to triangle DEC, so you can set up a ratio:

[tex]\frac{84}{156-x} = \frac{7}{x}[/tex]

Then cross multiply

84x = 7 (156 - x)

84x = 1092 - 7x

Add 7x to both sides.

91x = 1092

Divide both sides by 91.

x = 12

AC = 156 - x

AC = 156 - 12

AC = 144

Answer:

16

Step-by-step explanation:

You can think of -1/2 as -0.5, it sometimes helps

Two negatives multiplied equal a positive, eliminating choices A and B

When -0.5 is multiplied to the -4 power, it comes out to be 16

Hope this helps! Good luck :)

Answer:  t = [tex]\frac{y}{r} + \frac{2n}{r}[/tex]

Step-by-step explanation:

rt - 2n =  y        Add 2n to both sides

    +2n   +2n

rt = y + 2n       Divide both sides  by r

t= [tex]\frac{y}{r} + \frac{2n}{r}[/tex]  

Answer:

10+78t-16t^2

Step-by-step explanation:

(-16t-2)(t-5)

-16t × t= -16t²

-16t × -5=80t

-2 × t= -2t

-2 × -5=10

-16t²+80t-2t+10= -16t^2+78+10

Answer/Step-by-step explanation:

Given:

When Jada took 8 steps, Noah took 10 steps

When Jada took 12 steps, Noah took 15 steps

a. The following table can be created as follows given that x = steps taken by Jada, and y = steps taken by Noah:

From the info given, the ratio of Noah's steps to Jada's steps is 15 : 12 = 10 : 8 = 5 : 4 = ⁵/4.

Use this ratio to create a table of 3 pairs of values as shown below.

Jada's Steps (x) ===> Noah's steps (y)

4 ===> 5

8 ==> 10

12 ==> 15

b. The graph of that shows this relationship has been attached below. Check the attachment.

c. Constant of proportionality can be calculated in each representation as follows: y/x = k. Where y is steps taken by Noah, x is for steps taken by Jada, and I is constant of proportionality.

Thus,

Constant of proportionality (k) = 15/12 = ⁵/4

This means, for every 5 steps taken by Noah, Jada takes 4 steps.

This relationship is represented by the equation, y = ⁵/4x.

The ⁵/4 in the equation is the constant of proportionality of their relationship.

d. The equation, description, graph, and table all represent the same situation because they all show the same constant of proportionality between x and y.

In the equation, ⁵/4 represents the constant of proportionality. In the graph, the slope is ⁵/4, which is also the same last constant of proportionality.

In the table, the constant of change in each pair is ⁵/4 all through.
