Answer:

B) Its final coordinates are (8,-6)

Step-by-step explanation:

1. Translated 1 unit up and 4 units left

(-2,7) becomes (-6, 8)

2. Reflected about the x-axis

(-6,8) becomes (-6, -8)

3. Rotated 90° anticlockwise about the origin

(-6, -8) becomes (8, -6) because when rotating 90 degrees anticlockwise about the origin, point A (x,y) becomes point A' (-y,x). In other words, switch the x and y and make y negative.

a_sh-v [17]

Answer: conjunction and -20<x <16 is answer.

Step-by-step explanation:

It is a conjunction because it is and statement

|x+2|<18 gives

[Since l x-a l <b means x-a lies between -b and b ]

-18<x+2<18

subtracting 2 in the whole inequality ,we get

-18-2 <x +2-2 < 18-2

A box contains 144 marbles, which are either red or blue. if there are 3 times as many red marbles as there are blue marbles in

kicyunya [14]

Given:
X: The blue marbles.
3X: The red marbles.
A box contains 144 marbles.
SOLVING:
X + 3X = 144
4X = 144
X = $\frac{144}{4}$
X = 36 ===> The blue marbles.

If there are 3 times as many red marbles as there are blue marbles:
3(36) = 108 ===> The red marbles. SOLUTION

TESTING:
$36+108=144$
$\boxed{144}=\boxed{144}\quad\checkmark\ The\ value\ is\ correct.$
GOOD LUCK...!!!

The given system of equation is

$-9x+2y=-1..........(1)\\ \\ 18x-7y=17...........(2)\\ \\ \text{To solve the system of equation by elimination, multiply the first equation by 2 }\\ \text{and thereafter add equation 1 and 2 together we get }\\ \\ -18x+4y=-2\\ 18x-7y=17\\ ------\\ -3y=15\\ ------\\ \\ y=-5\\ \text{Now substitute the value of y in equation 1 we get }\\ \\ -9x-10=-1\\ \\ -9x=-1+10\\ \\ -9x=9\\ \\ x=-1\\ \\ \text{Hence the solution to the given system of equation is }\\ \\ x=-1, y=-5\\$
