<h3>Given</h3>

d = b² -4a

a = 5, b=12

<h3>Find</h3>

the value of d

<h3>Solution</h3>

Put the numbers where the corresponding letters are, then do the arithmetic.

d = 12² - 4·5

d = 144 - 20

d = 124

The appropriate choice is ...

... C. 124

The equation given is:

15x - 3y = 21


Slope intercept form is:

y = mx + b


15x - 3y = 21

-15x -15x

-------------------

-3y = -15x + 21

/-3 /-3 /-3

---------------------

y = 5x -7


The answer is: y = 5x - 7

Rectangle J'K'L'M' shown on the grid is the image of rectangle JKLM after transformation. The same transformation will be applie
Y_Kistochka [10]

Answer:

The coordinates of T' will be T'(13,-1)

Step-by-step explanation:

step 1

Find the rule of the translation

take any point of rectangle JKLM (pre-image)

The coordinate of point k(-3,2)

The coordinate of point k'(4,7)

so

The rule of the transformation

k(-3,2) -----> k'(4,7)

is equal to

(x,y) ------> (x+7,y+5)

That means ----> the translation is 7 units at right and 5 units up

step 2

Apply the rule of the translation at the coordinate T of trapezoid STUV

we have

T(6,-6)

(x,y) ------> (x+7,y+5)

T(6,-6) ------> T'(6+7,-6+5)

T(6,-6) ------> T'(13,-1)

therefore

The coordinates of T' will be T'(13,-1)
