Answer:

$\sqrt{ {28x}^{2} - 6x }$

Step-by-step explanation:

You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.

So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]

=Sqrt[7(4x²)-3(2x)]

=Sqrt[28x²-6x]

What is the solution when <br> 9x+6y=-3<br><br> x+8y=29

Leya [2.2K]

We have
$9x + 6y = - 3 - - - (1)$
and

$x + 8y = 29$
$\rightarrow \: x = 29 - 8y - - - (2)$

Using elimination will be faster, so plug in equation (2) in equation (1)

$9(29 - 8y) + 6y = - 3$

Expand brackets, we obtain,

$261-72y+6y=-3$
Simplifying gives,

$-66y=-264$

$y = \frac{ - 264}{ - 66} = 4$
$x = 29 - 8(4) = - 3$

Find the value of x and y. Show all your work neat and<br> in order.

Mazyrski [523]

Answer:

x = 21°

y = 29°

Step-by-step explanation:

a) Solving for x

Note that:

(3x - 3)° and 60° are Alternate interior angles, and alternate interior angles are equal to each other, hence:

3x - 3 = 60° (Alternate interior angles)

Add 3 to both sides

3x - 3 +3 = 60 + 3

3x = 63°

x = 63°/3

x = 21°

b) Solving for y

Notes that:

(3x - 3)° and (4y + 4)° are Consecutive interior angles and the sum consecutive interior angles is 180°

3x - 3 + 4y + 4 = 180°

3x + 4y - 3 + 4 = 180°

3x + 4y + 1 = 180°

Note that x = 21

Hence

3(21) + 4y + 1 = 180°

63 + 1 + 4y = 180°

64 + 4y = 180°

Subtract 64 from both sides

64 - 64 + 4y = 180° - 64

4y = 116°

y = 116/4

y => 29°
