The table of values represents an exponential function f(x).
Ostrovityanka [42]

Answer:

-3.98 (nearest hundredth)

Step-by-step explanation:

The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

\dfrac{f(b)-f(a)}{b-a}

Given interval:  -2 ≤ x ≤ 2

\implies a = -2

\implies b = 2

\implies f(a) = f(-2)=16

\implies f(b) =f(2)= \dfrac{1}{16}

Substituting the values into the equation:

\begin{aligned}\implies \textsf{rate of change} & =\dfrac{\frac{1}{16}-16}{2-(-2)}\\\\ & = \dfrac{-\frac{255}{16}}{4}\\\\ & = -\dfrac{255}{64}\\\\ & = -3.98\: \sf (nearest\:hundredth)\end{aligned}

X-Y-2Z =-11<br> X-2Y-Z = -11 <br> -X+Y+3Z = 14
Snowcat [4.5K]

9514 1404 393

Answer:

  (X, Y, Z) = (-2, 3, 3)

Step-by-step explanation:

We can subtract the second equation from the first to get ...

  Y -Z = 0

We can add the third equation to the first to get ...

  Z = 3

Then ...

  Y -3 = 0   ⇒   Y = 3

and ...

  X -3 -2(3) = -11

  X = -2 . . . . . . . . . add 9

The solution is ...

  (X, Y, Z) = (-2, 3, 3)

Which represents the solution(s) of the graphed system of equations, y = –x2 + x + 2 and y = –x + 3? (1, 2) (1, 2) and (0, 3) (–
max2010maxim [7]
Y = -x^2 + x + 2
y = -x + 3

-x + 3 = -x^2 + x + 2
x^2 - x - 2 - x + 3 = 0
x^2 -2x + 1 = 0
(x - 1)(x - 1) = 0

x - 1 = 0      y = -x + 3
x = 1           y = -1 + 3
                   y = 2

solutions are : (1,2) , (1,2)

73.7 is 55% of what number?
Vera_Pavlovna [14]

Answer:

a.) Let the total number be : x

∴(73.7÷x) ×100 = 55%

∴x= (73.7×100) ÷ 55

=> 7370÷55

∴x=134

Thus, Option-A.

----------------------------------------------------

b.) Let the percentage  be : x

∴x= (46÷65) ×100  

∴x= (0.707) × 100

∴x=70.7%

Thus, Option-B.
