Which of the following is equivalent to -2/3?

arlik [135]

Answer:

Step-by-step explanation:

-2/3 = -4/6 = -6/9 = -8/12

= -10/15 = -12/18 = -14/21 = -16/24

= -18/27 = -20/30 = -22/33 = -24/36

= -26/39 = -28/42 = -30/45 = -32/48

= -34/51 = -36/54 = -38/57 = -40/60

= -42/63 = -44/66 = -46/69 = -48/72

= -50/75 = -52/78 = -54/81 = -56/84

= -58/87 = -60/90 = -62/93 = -64/96

= -66/99 = -68/102 = -70/105 = -72/108

= -74/111 = -76/114 = -78/117 = -80/120

= -82/123 = -84/126 = -86/129 = -88/132

= -90/135 = -92/138 = -94/141 = -96/144

= -98/147 = -100/150 = -102/153 = -104/156

= -106/159 = -108/162 = -110/165 = -112/168

= -114/171 = -116/174 = -118/177 = -120/180

= -122/183 = -124/186 = -126/189 = -128/192

= -130/195 = -132/198 = -134/201 = -136/204

= -138/207 = -140/210 = -142/213 = -144/216

= -146/219 = -148/222 = -150/225 = -152/228

= -154/231 = -156/234 = -158/237 = -160/240

= -162/243 = -164/246 = -166/249 = -168/252

= -170/255 = -172/258 = -174/261 = -176/264

= -178/267 = -180/270 = -182/273 = -184/276

= -186/279 = -188/282 = -190/285 = -192/288

= -194/291 = -196/294 = -198/297 = -200/300

Answer:

x=50

See below for word problem.

Step-by-step explanation:

While shopping, you spend $125 before tax. You buy 3 dresses at the same price each and receive a $25 discount. How much is the price of each dress?

3x-25=125

3x=125+25

3x=150

x=50

Find the polynomial of lowest degree with only real coefficients and having the given zeros. -7i and square root of 2

mario62 [17]

Answer:

x³ - (√2)x² + 49x - 49√2

Step-by-step explanation:

If one root is -7i, another root must be 7i. You can't just have one root with i. The other roos is √2, so there are 3 roots.

x = -7i is one root,

(x + 7i) = 0 is the factor

x = 7i is one root

(x - 7i) = 0 is the factor

x = √2 is one root

(x - √2) = 0 is the factor

So the factors are...

(x + 7i)(x - 7i)(x - √2) = 0

Multiply these out to find the polynomial...

(x + 7i)(x - 7i) = x² + 7i - 7i - 49i²

Which simplifies to

x² - 49i² since i² = -1 , we have

x² - 49(-1)

x² + 49

Now we have...

(x² + 49)(x - √2) = 0

Now foil this out...

x²(x) - x²(-√2) + 49(x) + 49(-√2) = 0

x³ + (√2)x² + 49x - 49√2

HELPPPPPP!!!!!!!!!!!!!!!!!

Mnenie [13.5K]

Answer:

The student is wrong.

Step-by-step explanation:

To divide exponents (or powers) with the same base, subtract the exponents. In the second step, the wrong result is calculated.

$\frac{x^{\frac{6}{5}}}{x^{\frac{2}{5}}} = x^{\frac{4}{5}}$
