Distribute: 3x+6+4=5x+7
Simplify: 3x+10=5x+7
Subtract 3x from both sides: 10=2x + 7
Subtract 7 from both sides: 3=2x
Divide by 2: x=3/2

x=3/2

Answer:

8/15 = 16/30 = 24/45 = 32/60

= 40/75 = 48/90 = 56/105 = 64/120

= 72/135 = 80/150 = 88/165 = 96/180

= 104/195 = 112/210 = 120/225 = 128/240

= 136/255 = 144/270 = 152/285 = 160/300

= 168/315 = 176/330 = 184/345 = 192/360

= 200/375 = 208/390 = 216/405 = 224/420

= 232/435 = 240/450 = 248/465 = 256/480

= 264/495 = 272/510 = 280/525 = 288/540

= 296/555 = 304/570 = 312/585 = 320/600

= 328/615 = 336/630 = 344/645 = 352/660

= 360/675 = 368/690 = 376/705 = 384/720

= 392/735 = 400/750 = 408/765 = 416/780

= 424/795 = 432/810 = 440/825 = 448/840

= 456/855 = 464/870 = 472/885 = 480/900

= 488/915 = 496/930 = 504/945 = 512/960

= 520/975 = 528/990 = 536/1005 = 544/1020

= 552/1035 = 560/1050 = 568/1065 = 576/1080

= 584/1095 = 592/1110 = 600/1125 = 608/1140

= 616/1155 = 624/1170 = 632/1185 = 640/1200

= 648/1215 = 656/1230 = 664/1245 = 672/1260

= 680/1275 = 688/1290 = 696/1305 = 704/1320

= 712/1335 = 720/1350 = 728/1365 = 736/1380

= 744/1395 = 752/1410 = 760/1425 = 768/1440

= 776/1455 = 784/1470 = 792/1485 = 800/1500

Show your work on the question
AysviL [449]

Answer:

OPTION A: 3x - 1 = ± 5

Step-by-step explanation:

We have (3x - 1)² = 25

In OPTION A, Square root is taken on both sides.

This gives us: 3x - 1 = ± 5. And this is the logical follow - up of the previous step.

IN OPTION B: (a - b)² is wrongly expanded. So, this can not be the next step.

In OPTION C: The square root is taken only on the LHS but not on the RHS. So, it is eliminated.

In OPTION D: The square is expanded on LHS whereas on the RHS square root is taken. So, it is not correct and is eliminated.

Therefore, the correct option is A.

What is the equation for the translation of X^2+y^2=9 four units to the right and three units down
icang [17]
We know that
X²+y²=9 -------> X²+y²=3²
is the equation of a circle with center (0,0) and radius r=3 units
so
<span>the translation of four units to the right and three units down is equals to move the center (0,0)--------> (0+4,0-3)------> (4.-3)

the new center of the circle is (4,-3)
the new equation is
(x-4)</span>²+(y+3)²=3²

see the attached figure
