Answer:

A) x + y = 8

B) 3x + 2y = 21

We multiply A) by -2

A) -2x -2y  = -16 Then we add this to

B) 3x + 2y = 21

x = 5

y = 3

Second answer is correct

Which expression is equivalent to 144 superscript three-halves?
IrinaK [193]

Using the law of indices the equivalent expression of 144^{\frac{3}{2} } is 1728

<h3>How to find equivalent expression?</h3>

The equivalent expression of 144^{\frac{3}{2} } can be express as follows:

Using the law of indices,

(a^{b} )^{c}  = a^{bc}

Applying this laws,

144^{\frac{3}{2} }=(12^{2} )^{\frac{3}{2} }

Hence,

144^{\frac{3}{2} }=(12^{2} )^{\frac{3}{2} } = 12^{3}

Finally,

12³ = 1728

I WILL GIVE A FREAKING BRAINLIEST!!!!!!!!!!!
UkoKoshka [18]

Answer:

  0.5 < t < 2

Step-by-step explanation:

The function reaches its maximum height at ...

  t = -b/(2a) = -16/(2(-16)) = 1/2 . . . . . . where a=-16, b=16, c=32 are the coefficients of f(t)

The function can be factored to find the zeros.

  f(t) = -16(t^2 -1 -2) = -16(t -2)(t +1)

The factors are zero for ...

  x = -1 and x = +2

The ball is falling from its maximum height during the period (0.5, 2), so that is a reasonable domain if you're only interested in the period when the ball is falling.

Given f as described below.
Maru [420]

Answer:

f (0) = 0

Step-by-step explanation:

As <em>Domain = {all whole numbers} </em>

Range is <em>R = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} </em>

then f (0) = 0  which is its largest place value digit.
