Hi, there.

_____

» Multiply the equation by 2.

$\boldsymbol{2x+9=6}$

» Subtract 9 from both sides.

$\boldsymbol{2x=-3}$

» Divide both sides by 2.

$\boldsymbol{x=-\dfrac{3}{2}}$

Hope the answer - and explanation - made sense,

happy studying!!

Answer:

x = 5

Step-by-step explanation:

using the sine or cosine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{10}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 10 ( divide both sides by 2 )

x = 5

Your friend tells you that if you let her keep 2020 of your Pokemon cards for three months, she will give you 22 cards extra whe

Dmitrij [34]

Answer: 40 %

Step-by-step explanation:

Let the amount of one card = x

Hence, the value of 20 cards ( Principal amount ) = 20x

And, the value of 22 cards ( Total amount after 3 month ) = 22x

⇒ Total interest in 3 month = 22x - 20x =2x

Let the annual interest rate = r %

$\frac{20x\times r\times 3/12}{100}=2 x$ ( By the formula of simple interest rate )

$\implies \frac{10\times r\times 1/4}{100}=1$

$\implies \frac{10r}{400}=1$

$\implies 10r=400$

$\implies r=40\%$

Hence, the annual rate of interest = 40%

Which function below is the inverse of f(x) = x2 − 9?

Scorpion4ik [409]

F (x)=y
y=2x-9

X Y
-2 -15 y=2 (-2)-9
y=-4+-9
y=-15

-1 -11 y=2 (-1)-9
y=-2+-9
y=-11

0 -9 y=2 (0)-9
y=0+-9
y=-9

1 -7 y=2 (1)-9
y=2+-9
y=-1

2 -5 y=2 (2)-9
y=4+-9
y=-5

Here is all the work
