Square GYTD has vertices G(−4,3) , Y(0, 3) , T(0,−1) and D(−4,−1) . Square GYTD is translated 2 units left and 2 units up to

Sliva [168]

we know that

If square GYTD is translated $2$ units left and $2$ units up to produce square G'Y'T'D'

that means

the rule of transformation is

$(x,y)-------> (x-2,y+2)$

Find the coordinates of the image

$G (-4,3)------->G'(-4-2,3+2)=G'(-6,5)$

$Y (0,3)------->Y'(0-2,3+2)=Y'(-2,5)$

$T (0,-1)------->T'(0-2,-1+2)=T'(-2,1)$

$D (-4,-1)------->D'(-4-2,-1+2)=D'(-6,1)$

therefore

the answer is the option

G'(−6, 5), Y'(−2, 5), T'(−2, 1) , and D′(−6, 1)

Write the equation of a line in standard form that passes through (-2, 5) and is perpendicular to

sdas [7]

Answer:

Step-by-step explanation:

x - 2y = 8

Write this in y = mx +b form

- 2y = -x + 8

Divide the equation by (-2)

$\dfrac{-2y}{-2}=\dfrac{-x}{-2}+\dfrac{8}{-2}\\\\\\y =\dfrac{1}{2}x-4$

Slope = 1/2

The slope of the perpendicular line = -1/m

$=\dfrac{-1}{\dfrac{1}{2}}=1*\dfrac{-2}{1} = -2$

m = -2 , ( -2 , 5)

Equation: y = mx +b

Plug in m = -2 ,x = -2 and y =5

5 = (-2)*(-2) + b

5 = 4 + b

5 - 4 = b

b = 1

Equation of the line:

y = mx +b

y = -2x + 1

. 7 prizes are to be distributed between 3 people with a guarantee that each person gets at least one prize. Find the number of

ANEK [815]

Answer:

Total number of ways to distribute the prize = 2187

$3^{7}= 2187$

Step-by-step explanation:

Given:

Number of prizes = 7

Number of peoples = 3

We need to find the total number of ways to distribute the prize.

Solution:

From the above statement, 7 prizes are to be distributed between 3 people, wherein each person gets at least one prize.

Each prize is to be distributed among three persons. When the first prize is to be awarded, one of the three is chosen to win the prize. When the second prize is to be awarded, there are again three choices.

So, total number of distribution of the prizes is given as:

$3\times 3 \times 3\times 3\times 3\times 3\times 3=3^{7}$

$3^{7}= 2187$

Therefore, total number of ways to distribute the prizes = 2187

Find the value c that will make 9x^2 +30x+c a perfect square trinomial

anzhelika [568]

Answer:

$c = 25$

Step-by-step explanation:

Given :-

A quadratic equation is given to us.
The equation is 9x² + 30x + c .

And we need to find out the value of c for which the given trinomial is a perfect square. On looking at the given expression all the terms are having positive signs before them .So we can rewrite it on the basis of ,

Identity :-

$\implies (a+b)^2=a^2+b^2+2ab$
