Answer:

X = 4

Step-by-step explanation:

Since both 9x-6 and 30 equal f(x), we can set them equal to each other. Like this:

9x - 6 = 30

Now, just solve the equation

Add 6 to both sides

9x = 36

Then divide 9 on both sides

x = 4

Therefore, x is equal to 4.

Check:

9(4) - 6 = 30

36 - 6 = 30

30 = 30

I hope this helps!!

0/1 Solve the equation by completing the square. Round your answer to the nearest hundredth, if necessary x^2+18x=7

11111nata11111 [884]

Answer:

The solution to the equation is x = 0.38 or -18.38

Step-by-step explanation:

x^2+18x=7 can be properly written as

$x^{2} +18x =7$

To solve by completing the square, divide the coefficient of x by 2, square and then add to both sides

i.e 18/2 = 9

Then add 9² to both sides of the equation

$x^{2} +18x + 9^{2} = 7 + 9^{2}$

This becomes

$(x+9)^{2} = 7 + 81$

$(x+9)^{2} = 88$

$x+9 = \pm \sqrt{88}$

$x = -9 \pm\sqrt{88}$

$x = -9 \pm 9.38$

∴ $x = -9+9.38 or -9-9.38$

$x = 0.38 or -18.38$

Hence, x = 0.38 or -18.38

Answer: $\bold{a_n=2\bigg(\dfrac{1}{3}\bigg)^{n-1}}$

Step-by-step explanation:

$\text{The general form of the recursive rule is:}\ a_n=r\cdot a_{n-1}\\ \text{where r is the common ratio.}\ \text{The recursive rule provided is:}\\ a_n=\dfrac{1}{3}a_{n-1}\ \text{so, r} = \dfrac{1}{3}}\\\\\text{The general form of the explicit rule is:}\ a_n=a_1(r)^{n-1}\\\text{where}\ a_1\ \text{is the first term and r is the common ratio}.\\\\\text{So, the explicit rule with the information provided is:}\\a_n=2\bigg(\dfrac{1}{3}\bigg)^{n-1}$

two angles supplementary one angle measure 16 degrees more than three times the other find the measurement of each angle

MAXImum [283]

Answer:

the supplementary angles are 41° and 139°

Step-by-step explanation:

let one of the the supplymentary angle be x

the other angle = 3x + 16

now, since we know they are supplementary, their sum = 180°

=》x + 3x + 16° = 180°

=》4x = 180° - 16°

=》x = 164° ÷ 4

=》x = 41 °

so, one of the angles is x = 41°

the other one is : 3x + 16

=》(3 × 41°) + 16°

=》123° + 16°

=》139°
