What are the new vertices of the triangle under the translation (x, y) (x − 1, y − 3)?

balandron [24]

ANSWER

(-1,-1), (-4,-5), (-8,0)

EXPLANATION

We have a triangle with vertices:

(0,2), (-3,-2) and (-7,3).

The rule for the translation is

$(x, y) \to (x - 1,y - 3)$

The new vertices of the triangle will be;

$(0, 2) \to (0 - 1,2- 3) = ( - 1, - 1)$

$( - 3, - 2) \to (- 3-1, - 2- 3) = ( -4, - 5)$

$( - 7, 3) \to ( - 7 - 1,3- 3) = ( - 8, 0)$

The new vertices are:

(-1,-1), (-4,-5), (-8,0)

Solve 3x2 − 5x + 7 = 0. x equals the quantity of negative 5 plus or minus square root 109 all over 6 x equals the quantity of 5

gavmur [86]

Solve:

3x^2 - 5x + 7 = 0

Answer : x = 5/6 + i sqrt 59/6, x = 5/6 + i sqrt 59/6

Solve the Equation:

3x^2 - 5x + 7 = 0

Step 1: Use quadratic Formula with a = 3, b = -5, c = 7:

x = -b +/- sqrt b^2 - 4ac/ 2a

x = - ( - 5) +/- sqrt ( - 5)^2 - 4(3)(7)/ 2(3)

x = 5 +/- sqrt - 59/6, which will become, x = 5 +/- sqrt i 59/6, x = 5 +/- sqrt i 59/6

No Real Solutions:

Your answer would be, Letter Choice, (D), x equals the quantity of plus, or minus i sqrt 59 all over 6. Hence, No Real Solutions

Hope that helps!!!! : )

Which statements are true about the solution 2 < x - 7 and its graph? Check all that apply.

Mashutka [201]

Answer:

O x >9

The arrow points left

Step-by-step explanation:

Explanation:-

Given 2 < x-7

adding '7' on both sides, we get

⇒ 2 + 7 < x -7 +7

⇒ 9 < x

⇒ x>9

Given inequality 2 < x -7

The arrow points left

Final answer:-

solution is x >9

The arrow points left

Which of the following coordinate pairs make the equation x - 9y = 12 true?

Ne4ueva [31]

Options:

(12,0) (0,12) (3,-1) (0,-4/3)

Answer:

(12,0) , (3,-1) and (0,-4/3)

Step-by-step explanation:

Given

$x - 9y = 12$

Required

Which option is true?

A coordinate point is of the form; $(x,y)$

So, we have to substitute the x and y values in the given equation.

A. For (12,0)

$x = 12$ and $y = 0$

$x - 9y = 12$ becomes

$12 - 9*0 = 12$

$12 - 0 = 12$

$12 = 12$

This is true

B. For (0,12)

$x = 0$ and $y = 12$

$x - 9y = 12$ becomes

$0 - 9*12 = 12$

$- 9*12 = 12$

$- 108 = 12$

This is false

C. For (3,-1)

$x =3$ and $y = -1$

$x - 9y = 12$ becomes

$3 - 9*-1 =12$

$3 + 9 =12$

$12 = 12$

This is true

D. For (0,-4/3)

$x = 0$ and $y = -\frac{4}{3}$

$x - 9y = 12$ becomes

$0- 9*-\frac{4}{3} = 12$

$0+ 9*\frac{4}{3} = 12$

$0+ 3*4 = 12$

$0+12 = 12$

$12 = 12$

This is true

Hence, (12,0) , (3,-1) and (0,-4/3) are true values of the equation
