-4(a+3)+8-3(2a-8)=30

USPshnik [31]

If you’re solving for a... subtract the 8 to the other side so...
-4(a+3)- 3(2a-8) = 22.
Distribute the -4 and -3 into the parentheses (two negatives multiplied together is a positive)...
-4a-12-6a+24 = 22.
Add the constants and a’s together.
-10a + 12 = 22
Subtract 12 to the other side.
-10a = 10
Divide both sides by -10.
a = -1
Check and make sure that this answer works with the problem.
-4(-1+3)-3(-2-8)=22
-4(-2)-3(-10)=22.
-8+30=22.
22=22, the answer checks out

PLEASE HELP I have been trying to figure this out for a really long time and I want to get the best grade on my test !

Shalnov [3]

Answer:

see below

Step-by-step explanation:

$-4^{2} =-16\\\\-\sqrt{4} =-2\\\\\sqrt{4^{2} } =4\\\\-2\sqrt{4} =-4\\\\(-4)^{2} =16\\\\\sqrt{1/4} =1/2$

so the order

-16

-4

-2

1/2

4

16

in root forms and exponent

$-4^{2} \\\\-2\sqrt{4} \\\\-\sqrt{4} \\\\\sqrt{\frac{1}{4} } \\\\\sqrt{4^{2} } \\\\(-4 )^{2}$

The average revenue of a TV manufacturing unit is given by r(x)=75x^2-5x^3/2 where x is the number of TVs sold by the firm. Find

olga nikolaevna [1]

Answer:

The total revenue generated by the firm is:

$P(x) = 75x^3-5x^{\frac{5}{2}}$

Step-by-step explanation:

The average cost per TV is:

$r(x) =\frac{P(x)}{x}$

Where x is the number of televisions sold and P is the firm's income for all the televisions sold

In this problem we know the equation r(x).

Then P(x) will be:

$P(x) = x*r(x)$

Therefore if $r(x)=75x^2-5x^{3/2}$ then

$P(x) = x*(75x^2-5x^{3/2})$

$P(x) = 75x^{2+1}-5x^{\frac{3}{2}+1}\\\\P(x) = 75x^3-5x^{\frac{5}{2}}$
