Arrange the functions in ascending order, starting with the function that eventually has the least value and ending with the fun
natali 33 [55]
The main factor when x values are high is the nature of the function. For example, polynomial functions intrinsically grow slower than exponential functions when x is high. Also, the greater the degree of the polynomial, the more the function grows in absolute value as x goes to very large values.

In specific, this means that our 2 exponential functions grow faster than all the other functions (which are polynomial) and thus they take up the last seats. Also, 7^x grows slower than 8^x because the base is lower. Hence, the last is 8^x+3, the second to last is 7^x.

Now, we have that a polynomial of 2nd degree curves upwards faster than a linear polynomial when x is large. Hence, we have that the two 2nd degree polynomials will be growing faster than the 2 linear ones and hence we get that they fill in the middle boxes. Because x^2+4>x^2, we have that x^2+4 is the 4th from the top and x^2 is the 3rd from the top.

Finally, we need to check which of the remaining functions is larger. Now, 5x+3 is larger than 5x, so it goes to the 2nd box. Now we are done.

A vacant city lot is being turned into a neighborhood garden. the neighbors want to fence in a triangular section of the lot and
Alexxx [7]

Let x represent the length of the shortest side. Then the longest side is

... 2x -7 . . . . . . 7 ft shorter than twice the shortest side

and the 3rd side is

... x +2 . . . . . . 2 ft longer than the shortest side.

The perimeter is the sum of the side lengths,

... x + (2x -7) + (x +2) = 59 . . . . . the given perimeter length

... 4x -5 = 59 . . . . collect terms

... 4x = 64 . . . . . . add 5

... x = 16 . . . . . . . . divide by 4

Then the other sides are

... 2×16 - 7 = 25 . . . . . longest side

... 16 +2 = 18 . . . . . . . . third side

The side lengths are 16 ft, 18 ft, and 25 ft.

Solve the system of equations:<br><br> -5x+y-4z=60<br> 2x+4y+3z=-12<br> 6x-3y-2x=-52
Bogdan [553]

Answer:

The answer to your question is:

x = -8; y = 1 ; z = -4

Step-by-step explanation:

Δ = \left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]

  = 40 + 24 + 18 - (-4 + 45 - 96)

 = 82  + 55

 = 137

Δx = \left[\begin{array}{ccc}60&1&-4\\-12&4&3\\-52&-3&-2\end{array}\right]

= - 480 - 144 - 156 - ( 24 - 540 + 832)

= -780 -316

= - 1096

Δy = \left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]

= 40 + 24 + 18 - ( - 4 + 45 - 96)

= 82 + 55

= 137

Δz = \left[\begin{array}{ccc}-5&1&60\\2&4&-12\\6&-3&-52\end{array}\right]

= 1040 - 360 - 72 - ( - 104 - 180 + 1440)

= 608 - 1156

= -548

x = -1096/ 137 = -8

y = 137 / 137 = 1

z = -548 / 137 = -4
