Busca dos números consecutivos de manera que la diferencia de sus cuadrados sea 19
deff fn [24]
The numbers are 9 and 10.

Let x be the first number.  Since they are consecutive, this means (x+1) represents the second number.

The square of x is x².  The square of (x+1) is
(x+1)²=(x+1)(x+1)=x²+1x+1x+1=x²+2x+1

The difference of these squares would be given by
x²+2x+1 - x²

Setting this equal to 19,
x²+2x+1 - x² = 19

Combining like terms,
2x+1=19

Subtract 1 from each side:
2x+1-1=19-1
2x=18

Divide both sides by 2:
2x/2 = 18/2
x = 9

The first number, x, is 9.  This means the second number, x+1, is 9+1=10.

Which of the following is the graph of f(x)= 3 sin 2(x)?​
svetoff [14.1K]

Answer:

Step-by-step explanation:

Use the form  a sin ( bx- c) + d   to find the variables used to find the amplitude, period, phase shift, and vertical shift.

a = 3

b =  2

c  =  0

 d  =  0

Find the amplitude  |  a |

Amplitude:  3

Find the period using the formula  2π ÷ IbI

Period:  π

Find the phase shift using the formula  \frac{c}{b}

Phase Shift:  0

Find the vertical shift  : d

Vertical Shift:  0

List the properties of the trigonometric function.

Amplitude:  3

Period:  π

Phase Shift:  0  ( 0  to the right)

Vertical Shift:  0

Select a few points to graph.

x                       f ( x )

0                        0

π ÷ 4                 3

π  ÷ 2                 0

3 π  ÷ 4              -3

π                         0

 The Trignometric  function can be graphed using the amplitude, period, phase shift, vertical shift, and the points.

Amplitude:  3

Period:  π

Phase Shift:  0  ( 0  to the right)

Vertical Shift:  0

x                       f ( x )

0                        0

π ÷ 4                 3

π  ÷ 2                 0

3 π  ÷ 4              -3

π                         0

HELP!!!!!!! Choose the graph that matches the following system of equations:
pshichka [43]

Answer:

The answer in the attached figure

Step-by-step explanation:

we have

4x + 2y = -2 -----> equation A

x-3y=24 -----> equation B

Isolate the variable x in the equation B

x=3y+24 ----> substitute in the equation A and solve for y

4(3y+24) + 2y = -2

12y+96+ 2y = -2

14y = -2-96

14y = -98

y = -7

Find the value of x

x=3(-7)+24=3

The solution of the system of equations is the point (3,-7)
