To solve the equation, Antwan uses the distributive property, combines like terms, then uses the addition and subtraction proper

nikdorinn [45]

Answer:

The value of x is $-\frac{28}{5}$ .

Step-by-step explanation:

The distributive property is:

a (b + c) = a · b + a · c

The expression is:

$3(\frac{1}{3}x+1)+4=-1-4(x+3)-3$

Solve using the distributive property as follows:

$3(\frac{1}{3}x+1)+4=-1-4(x+3)-3$

$(3\cdot \frac{1}{3}x)+(3\cdot 4)=-1-(4\cdot x)-(4\cdot 3)-3\\\\x+12=-1-4x-12-3\\\\x+4x=-16-12\\\\5x=-28\\\\x=\frac{-28}{5}$

Thus, the value of x is $-\frac{28}{5}$ .

Answer:

for #9:

tan 30=x/10

tan 30*10=x

x=5.77=5.8

for #10:

tan 40=4/x

x*tan 40=4

x=4/tan 40

x=4.76=4.8

Which of the following constants can be added to x^2+2/3 to form a perfect square trinomial?

Lera25 [3.4K]

As your question is stated, there is no answer!

I'm going to assume the polynomial you meant is:

$x^2 + \frac{2}{3} x$

To create a perfect square trinomial, take half the coefficient of x and then square it.

$\left( \frac{1}{2} \times \frac{2}{3} \right) ^2 = \left(\frac{1}{3} \right) ^2 =\frac{1}{9}$

In all problems like this, you want to square half the coefficient of x -- always half.

If F(x) = log 4 3x, find F -1(x). A.4^y=3x B.4^x=3y C.4^3y=x

lara31 [8.8K]

Answer:

${f}^{ - 1} (x) = \frac{{4}^{x} }{3}$

Step-by-step explanation:

The given logarithmic function is

$f(x) = log_{4}(3x)$

Let y=f(x)

This gives us:

$y = log_{4}(3x)$

We interchange x and y to get:

$x = log_{4}(3y)$

${4}^{x} = 3y$

$y = \frac{{4}^{x} }{3}$

Therefore the inverse is

${f}^{ - 1} (x) = \frac{{4}^{x} }{3}$

Based on the possible answers, B is most closed to the inverse.

The correct answer is B
