4 0


8y-3=6y+17

add 3 on both sides

8y=6y+20

-6y on both sides

2y=20

divide by 2 on both sides

y=10

Can you help me please ​
alexira [117]

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

|v|=38

Ф = 120°

<u>Finding the horizontal component</u>

The horizontal component can be obtained using the formula

Vx = |v| cos Ф

     = 38 cos 120°

     = 38 (-0.5)

      = -19

Thus, the  horizontal component is:

Vx = -19

<u>Finding the vertical component</u>

The vertical component can be obtained using the formula

Vy = |v| sin Ф

    = 38 sin 120°

    = 38 (0.86)

    = 32.68

Thus, the vertical component is:

Vy = -19

  • A vector 'v' with magnitude |v| and direction Ф can be written as:

v = |v| cos Ф i + |v| sin Ф j

As

|v|=38

Ф = 120°

Thus, the vector is

v = 38 cos 120° i + 38 sin 120° j

or

v = -19 i + 32.68 j

Solve the following proportions<br> 3/x-3=8/2x+6<br> X=
Rzqust [24]

Answer:

21

Step-by-step explanation:

3/(x-3) = 8/(2x+6)

or, 3(2x+6) = 8(x-3)   ( by cross multiplication)

or, 6x + 18 = 8x - 24

or, 8x - 6x = 24 + 18

or, 2x = 42

or, x = 42/2

=21

The graph of f(x) = x3 + x2 - 9x - 9 is shown.
AysviL [449]

Answer:

-1, 3, -3

Step-by-step explanation:

I don't see the graph, but you can solve by factoring:

x^3+x^2-9x-9=0\\x^2(x+1)-9(x+1)=0\\(x+1)(x^2-9)=0\\(x+1)(x+3)(x-3)=0

By the factor theorem, the solutions of f(x) are -1, 3, and -3.

Look at the expression you entered in the table in part C. Write them backward as a sum, starting with the amount from month 12.
atroni [7]

Answer: =

Write the expressions backward from month 12 to month 1 to get this series:

50 + 50(1.003) + 50(1.003)2 + ... + 50(1.003)11

Convert the series to sigma notation, and find the sum of the 12 terms in the series:

11

S12 50(1.003)

ko

50(1 - 1.00312)

1 - 1.003
