Write an algebraic rule to describe the translation C(5, –4) C’(–2, 1)

Answers

Answer:

The required algebraic rule of translation is (x,y)\rightarrow (x-7,y+5).

Step-by-step explanation:

The coordinates of a point are C(5, –4) and the coordinates of image are C’(–2, 1).

C(5,-4)\rightarrow C'(-2,1)           .... (1)

Let the algebraic rule of translation is

(x,y)\rightarrow (x+a,y+b)           .... (2)

From (1) and (2) we get

x=5,y=-4

x+a=-2

5+a=-2

a=-2-5

a=-7

The value of a is -7.

y+b=1

-4+b=1

b=1+4

b=5

The value of b is 5.

The algebraic rule of translation is

(x,y)\rightarrow (x-7,y+5)

Therefore the required algebraic rule of translation is (x,y)\rightarrow (x-7,y+5).
We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)

So, plugging in the values and solving for a and b,
5 + a = -2
a = -8

-4 + b = 1
b = 5

Therefore, the translation is
(x,y) (x - 8, y +5)

What is 75 1/3% as a fraction in simplest form

Answers

Step 1

Convert a mixed number in a proper fraction

we know that

75(1)/(3)\%=((75*3+1))/(3) =(226)/(3)\%

therefore

the answer is

(226)/(3)\%
75*3=225+1=226=226/3

A basketball player gets 2 free-throw shots when she is fouled by a player on the opposing team. She misses the first shot 40% of the time. When she misses the first shot, she misses the second shot 5% of the time. What is the probability of missing both free-throw shots?

Answers

The probability of missing the first shot is 40%. When she misses the first shot, the probability of missing the second shot is very, very low, only 5%. That means that the probability of missing both shots must be much smaller than the probability of missing the first shot.

How many solutions are there to the system of equations? 4x-5y=5 -0.08x+0.10y=0.10

Answers

Using substitution method, the system of linear equations has no solution.

What is the solution to the system of equations?

To determine the solution to the system of equations, we can use substitution method;

4x - 5y = 5 ...eq(i)

-0.08x + 0.10y = 0.10 ...eq(ii)

From equation (i)

4x - 5y = 5

let's make x the subject of formula;

4x = 5 + 5y

x = (5 + 5y) / 4 ...eq(iii)

Put eq(iii) into equ(ii)

-0.08[(5 + 5y)/4] + 0.10y = 0.10

(-2/5 - 2/5y)/4 + 0.10y = 0.10

y = no solution

Since y has no solution, this implies that the system of linear equations has no solution.

Simple..

you have:

4x-5y=5

-0.08+0.10y=0.10

Take....

4x-5y=5----> *1 -----> 4x-5y=5

-0.08+0.10y=0.10---> *50---->-4x+5y=5

Now....

4x-5y=5
-4x+5y=5

As you may be able to tell it has no solution.

Thus, your answer.

What is the answer to this problem?  7.5/12=4.2/x

Answers

Answer:

x = 67.2

Step-by-step explanation:

7.5/12 = 4.2/x

First, divide 7.5 by 12.

0.625 = 42/x

Next, multiply both sides by x

0.625x = 42

Next, divide by 0.625

x = 67.2

There's your answer!

Answer:

Answer is 6.720
