3x-2= 4x+9/3 whats the solution

Answers

Answer 1

Answer: The answer is x=-5
Hope this helps!

Answer 2

Answer: 3 x - 2 = 4 x + 9/3

Multiply both sides of the equation by 3

9 x - 6 = 4x + 9

Move variable to the left-hand side and change its sign

9 x - 4 x - 6 = 9

Collect like terms

5 x = 9 + 6

Divide both side of the equation by 5

X = 3

And you answer is X = 3

Thanks :)

Step-by-step explanation:

5) 6 : 18 = $(6*1)/(6*3) = 1 : 3$

6) $10 : 12 = (2*5)/(2*6) = (5)/(6)= 5 : 6$

To reduce to simplest form, find Greatest Common Factor of the two numbers and divide both numbers by the GCF

21 = 3 * 7

9 = 3 * 3

GCF = 3

$(21)/(9)=(3*7)/(3*3)=(7)/(3)=7:3$

Answers

Answer:

x = 90 degrees and y = 43 degrees

Step-by-step explanation:

We have an isosceles triangle here, since the length of AB equals the length of AC.

That also means that angle ABC equals angle ACD = 47 degrees.

The sum of the interior angles of a triangle equals 180.

47 + 47 + 2y = 180

94 + 2y = 180

2y = 86

y = 43 degrees

x + 43 + 47 = 180

x + 90 = 180

x = 90

A(x)=(2x-5)(x+1)-(5x-3)(2x-5)

Answers

Answer:

-8x² + 28x - 20

Step-by-step explanation:

To simplify the expression A(x) = ( 2x - 5 )( x + 1 ) - ( 5x - 3 )( 2x - 5 ), you can start by using the distributive propertyto expand both sets of parentheses and then combine like terms:

A ( x ) = ( 2x - 5 ) ( x + 1 ) - ( 5x - 3 ) ( 2x - 5 )

Expand the first set of parentheses.

( 2x - 5 ) ( x + 1 )

2x ( x ) + 2x ( 1 ) - 5 ( x ) - 5 ( 1 )

2x² + 2x - 5x - 5

Now, expand the second set of parentheses.

( 5x - 3 ) ( 2x - 5 )

5x ( 2x ) + 5x ( -5 ) - 3 ( 2x ) - 3 ( -5 )

10x² - 25x - 6x + 15

Now, let's combine like terms within each part.

2x² + 2x - 5x - 5 - ( 10x² - 25x - 6x + 15)

Distribute the negative sign to both terms in the second parentheses.

2x² + 2x - 5x - 5 - 10x² + 25x + 6x - 15

Combine like terms in the entire expression.

( 2x² - 10x² ) + ( 2x - 5x + 25x + 6x ) + ( -5 - 15 )

Simplify further.

-8x² + 28x - 20

∴ A ( x ) = -8x² + 28x - 20

A species of plant experiences exponential growth after it is introduced into an area where it has never been. Which statement best describes exponential growth?

Answers

Answer:

C. Within a few years the population increases dramatically

True. As we can see on the function $A = A_o e^(rt)$ if we increase the time by 10 units for example the final amount is increasing by a factor of $e^(10)=22026.47$ and that represent a dramatically increase.

Step-by-step explanation:

When we have a exponential growth model the general formula is given by:

$A = A_o e^(rt)$

Since says "growth" the rate of increase r>0, $A_o$ represent the initial amount and A the amount after the time t.

Assuming the possible options for the answer. We analyze one by one

A. Each individual plant grows much larger than usual

False, for this model we assume that all the individuals in the population modeled have similar characteristics, because if the individuals are different we can't use a deterministic model like this one.

B. The population immediately decreases

False. We are assuming that the model is for a growth rate so then is not possible to have a decrease.

C. Within a few years the population increases dramatically

D. The specie's reproductive potential declines

False, we are considering a growth model in which it makes no sense to consider that the potential, population or quantity measured decrease.
