5. Solve the following equation for A : 2A/3 = 8 + 4A

denpristay [2]

Answer:

Step-by-step explanation:

Given

$\frac{2A}{3}$ = 8 + 4A

Multiply through by 3 to clear the fraction

2A = 24 + 12A ( subtract 12A from both sides )

- 10A = 24 ( divide both sides by - 10 )

A = - 2.4 → A

I need help! 50 points + brainliest

Answer:

Part 1)

Part 2)

Step-by-step explanation:

We are given:

$f(x)=5x+1\text{ and } g(x)=x^2-9$

And that:

$h(x)=f(x)/g(x)$

And we want to now for which values of x is h(x) undefined.

So, by substitution:

$\displaystyle h(x)=\frac{5x+1}{x^2-9}$

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.

This is because we cannot divide by 0.

So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

$x^2-9=0$

Add 9 to both sides:

$x^2=9$

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

$x=\pm 3$

So, h(x) is undefined for ±3.

Our answer is A.

We are given:

$f(x)=3^x\text{ and } g(x)=3^{2x}-3^x$

And we want to find:

$h(x)\text{ if } h(x)=f(x)-g(x)$

So:

$h(x)=3^x-(3^{2x}-3^x)$

Distribute:

$h(x)=3^x-3^{2x}+3^x$

Combine like terms:

$h(x)=2(3^x)-3^{2x}$

Rewrite:

$h(x)=2(3^x)-(3^x)(3^x)$

Factor out:

$h(x)=3^x(2-3^x)$

So, our answer is C.

1.09. You want to add all the numbers together which would give you 12 and divide that by how many numbers there are which is 11. So 12 divided by 11 would give you roughly 1.09 !

The slope of the line below is 3. Use the coordinates of the labeled point to

Makovka662 [10]

The point-slope equation of the line is y - 8 = 3(x - 6)

<h3>How to determine the equation?</h3>

The points are given as:

(x1, y1) = (6, 8)

The slope is given as:

m= 3

The equation is then calculated as:

y - y1 = m(x - x1)

This gives

y - 8 = 3(x - 6)

Hence, the point-slope equation of the line is y - 8 = 3(x - 6)

State the degree of the polynomial -x4

emmainna [20.7K]

-x^4

The degree is the exponent, and he amount of degrees there are depends on the amount of degrees in each monomial.

In this case, there is only one monomial, with it's degree as 4

4 is your answer

hope this helps
