Equal sets have the exact same elements, so they must have the same number of elements. Therefore, equal sets must also be equivalent. No, not all equivalent sets are also equal sets

\\ \rm\longmapsto \dfrac{x-3}{4}=\dfrac{x}{2}

\\ \rm\longmapsto 2(x-3)=4x

\\ \rm\longmapsto x-3=\dfrac{4x}{2}

\\ \rm\longmapsto x-3=2x

\\ \rm\longmapsto x-2x=3

\\ \rm\longmapsto -x=3

If f'(x) is (x-4)(4-2x) , what is f(x)?
butalik [34]
We can apply some rules backwards

first
f'(x)=
(x-4)(-2x+4)
-2x^2+12x-16

we know that
f'(rx^n)=rnx^{n-1}
so therefor maybe
-2x^2=rnx^{n-1}
2=n-1
n=3
rn=-2
3r=-2
r=-2/3

one is
\frac{-2}{3}x^3
second part

12x
12x=rnx^{n-1}
x^1, 1=n-1
n=2
rn=12
2r=12
r=6
6x^2 is the second bit

last part
-16
-16x^0=rnx^{n-1}
0=n-1
n=1

rn=-16
1r=-16
r=-16

-16x^1

so therfor f(x)=\frac{-2}{3}x^3+6x^2-16x

Pls help me help me help me​
Ganezh [65]

Answer:

C. -3/2

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

We know that line <em>m </em>is perpendicular to line <em>l. </em>

Line <em>l </em>has a slope of 2/3. To find the slope of line <em>m, </em>find the negative reciprocal of 2/3.

Negative: switch the sign

2/3 --> -2/3

Reciprocal: switch the numerator (top number) and denominator (bottom number)

-2/3 --> -3/2

Line <em>m</em> has a slope of -3/2 and C is correct.

4 times x with an exponent of 2 plus 2 times y with an exponent of 4. X=-3 y=2
Digiron [165]

Answer:

Step-by-step explanation:

Your equation is: 4*x^{2} +2 * y^{4}

You also know that x = -3 and y = 2. You can rewrite the equation by substituting x and y with their actual values:

4*(-3)^{2} +2 * 2^{4}

First, you want to do the exponentiation (meaning you want to calculate (-3)^{2} and 2^{4} parts). (-3)^{2} equals 9 and 2^{4} equals 16.

So the equation now is:

4*9+2*16

Now you want to do multiplication. 4*9 equals 36 and 2*16 equals 32. So you're left with:

36+32

Which equals 68.

When is the product of two nonzero integers less than or equal to both of the two factors
Sergeu [11.5K]
1) if they're both 1:

1 x 1 = 1: they preoduct is equal to both factors!

2) if one of them is negative (but not 2!)

for example: -2 and 6: the product is -12, and it's less than both -2 and  6!!!
