Answer: See below

Step-by-step explanation:

The general transformation equation for an absolute value function is

y=a | x−h |+k.

f(x)=|x+4|

Horizontal translation 4 units left (positive value, move left)

f(x)=|x|-4

Vertical translation down 4 units (negative k value, move down)

f(x)=|x-4|

Horizontal translation 4 units right (negative value, move right)

f(x)=|x|+4

Vertical translation up 4 units (positive k value, move up)

Answer:

Step-by-step explanation:

General form of circle: (x - h)² + (y- k)² = r²

r - > radius and h ,k are the coordinates of the center.

5) (x - 5)² + (y- 1)² = 64 = 8²

radius: 8 ; Center (5 , 1)

6) (x + 7)² + (y- 2k)² = 324 = 18²

Center = ( -7 , 2) ; radius = 18 ; diameter = 18 *2 = 36

7) (x )² + (y + 10)² = 42.25 = 6.5²

Center = (0 , - 10); radius = 6.5 ; diameter = 6.5*2 = 13

8) (x - 6)² + (y + 1)² = 80 = (4√5)²

Center =(6, -1) ; radius = 4√5

What is the value of the expression?

bulgar [2K]

The answer is 64. You must follow the order of operations, so you do what is in the parenthesis first. 15-7=8 and 5+3=8. Once you calculate that, you do 8×8=64.

What is the solution of the system?

Kryger [21]

Greetings!

Solve the System, using Elimination:
$\left \{ {{4x+2y=18} \atop {2x+3y=15}} \right.$

Multiply Equation #2 by 2:
$\left \{ {{4x+2y=18} \atop {2(2x+3y)=2(15)}} \right.$

$\left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.$

Eliminate variable x:
$-\frac{ \left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.}{0x-4y=-12}$

$4y=-12$

Divide both sides by 4:
$\frac{4y}{4}= \frac{12}{4}$

$y=3$

Input this value into one of the Equations:
$4x+2y=18$

$4x+2(3)=18$

Simplify:
$4x+6=18$

$(4x+6)+(-6)=(18)+(-6)$

$4x=12$

Divide both sides by 4.
$\frac{4x}{4}= \frac{12}{4}$

$x=3$

The Solution to this System (The Point of Intersection):
$\boxed{(3,3)}$

I hope this helped!

15 point help asap marking brainlest!!!!!!!!!!!!!!

ziro4ka [17]

slope =(y2-y1)/(x2-x1)

m=(-1-5)/(1--1)

m=-6/2

m=-3

y-y1=m(x-x1) point slope form

y-5 = -3 (x--1)

y-5 = -3 (x+1)

distribute

y-5 = -3x -3

add 5 to each side

y = -3x+2

A tabletop in the shape of a trapezoid has an area of 5,350 square centimeters. Its longer base measures 135 centimeters, and th

borishaifa [10]

Answer:

54 cm

Step-by-step explanation:

Using the formula for the area of a trapezoid (area is the sum of the two bases times the height and then halved):

A = 1/2 (h) (b1 + b2)

5350 = 1/2 (h) (135 + 65)

5350 = 1/2 (h) (200)

5350 = h (100)

5350/100 = h

h = 53.5

h ≈ 54 cm
