Answer:

Step-by-step explanation:

Your line has the wrong slope. Its slope is ½, but the equation tells you that the slope is ¾.

The point (0,2) is correct, but (-4,0) is incorrect. If x=-4 then y=-1, not 0.

Plot (-4,-1), then draw the line passing through (-4,-1) and (0,2).

Use the euclidean algorithm to find

kvasek [131]

A)
$18=1\cdot12+6$
$12=2\cdot6+0$
$\implies\mathrm{gcd}(12,18)=6$

b)
$201=1\cdot111+90$
$111=1\cdot90+21$
$90=4\cdot21+6$
$21=3\cdot6+3$
$6=2\cdot3+0$
$\implies\mathrm{gcd}(111,201)=3$

c)
$1331=1\cdot1001+330$
$1001=3\cdot330+11$
$330=30\cdot11+0$
$\implies\mathrm{gcd}(1001,1331)=11$

d)
$54321=4\cdot12345+4941$
$12345=2\cdot4941+2463$
$4941=2\cdot2463+15$
$2463=164\cdot15+3$
$15=5\cdot3+0$
$\implies\mathrm{gcd}(12345,54321)=3$

e)
$5040=5\cdot1000+40$
$1000=25\cdot40+0$
$\implies\mathrm{gcd}(1000,5040)=40$

f)
$9888=1\cdot6060+3828$
$6060=1\cdot3828+2232$
$3828=1\cdot2232+1596$
$2232=1\cdot1596+636$
$1596=2\cdot636+324$
$636=1\cdot324+312$
$324=1\cdot312+12$
$312=26\cdot12+0$
$\implies\mathrm{gcd}(9888,6060)=12$

10 POINTS! PLEASE HELP!! The illustration shows a compact disc tray that holds five CDs. The radius of each compact disc is 9 cm

MariettaO [177]

We can see that there are 5 CDs, each of radius 9 cm

Area occupied by 1 disc:

Area of a circle = πr²

Area of disc = π(9)²

Area of disc = 3.14 * 81 = 254 cm²

Area occupied by 5 discs:

Area occupied by 5 discs = Area occupied by 1 disc * 5

Area occupied by 5 discs = 254 * 5

Area occupied by 5 discs = 1270 cm²

Think carefully about the angle relationship the following represents.

lisov135 [29]

Answer:

See below ↓↓↓

Step-by-step explanation:

Subquestion #1

These angles form a linear pair
They are supplementary, and add up to 180°
2x + 48 = 180
2x = 132
x = 66

Subquestion #2

These angles are complementary, and add up to 90°
35 + 4x + 7 = 90
4x + 42 = 90
4x = 48
x = 12

Subquestion #3

As in #1, they are a linear pair, and are supplementary
3x + 54 = 180
3x = 126
x = 42
