Answer 1

Answer:

Answer:

$(-7, -6)$

Step-by-step explanation:

Use the definition of midpoint:

$M=((x_(1)+x_(2) )/(2),(y_(1)+y_(2) )/(2) )$

And replace the known values in:

$(-1, -2)=((5+x_(2) )/(2), (2+y_(2) )/(2) )\n(-7, -6)=(x_(2) , y_2)$

Short and neat :)

log3(2x-5)=2

Answer is 41/2. Why?

Answers

I guess that your question is:

$log[6*(2x-5)]=2$

So, we can apply this property of log

$log_b~(a)=c\Leftrightarrow a=b^c$

them...

$log[6*(2x-5)]=2$

$6*(2x-5)=10^2$

$12x-30=100$

$12x=100+30$

$12x=130$

$x=(130)/(12)$

simplifying

$\boxed{\boxed{x=(65)/(6)}}$

Answer:

0.954243x−2.385606=2

Let's solve your equation step-by-step.

0.954243x−2.385606=2

Step 1: Add 2.385606 to both sides.

0.954243x−2.385606+2.385606=2+2.385606

0.954243x=4.385606

Step 2: Divide both sides by 0.954243.

0.954243x/0.954243 = 4.385606/0.954243

5 packets of different sizes have a total mass of 800 g find their average mass

Answers

$(800g)/(5 packets) = (160g)/(1 packet) average mass$

To find the average of a quantity, we simply take the total and divide by the number of products contributing to that data:
800/5 = 160g

Which expression is not a polynomial?

Answers

The expression that is not a polynomial is $(x^(2) - x - 12 )/(x + 3)$

A polynomial function is a function that is made up of non-zero coefficients, positive exponents, and constants.

Types of polynomials

1. Linear polynomial function: it is made up of one variable raised to the power of 1.

An example is y + 10

2. Quadratic polynomial function - it is made up of a variable that is raised to the power of two.

An example is x² + 10x + 25

3. Cubic polynomial function: a single power is raised to the power of three.

An example is 124y³ + y²

The following are not polynomials:

An expression that is divided by another variable.
An expression with a negative exponent
An exponent that is a decimal.

Step-by-step explanation:

The rules of exponents say that a polynomial CAN'T have a variable as a denominator. Option A violates that rule, since it has x + 3 as a denominator.

If all angles are 108 degrees how many sides is there for a regular polygon

Answers

Sum of interior angles = 180(n-2)
Where n= the number of sides in the polygon

A polygon is called a regular polygon when all of its sides are the same length and all of its angles are the same measure.A regular polygon is both equilateral and equiangular. To find the sum of its interior angles, substitute n = 5 into the formula 180(n - 2) and get 180(5 - 2) = 180(3) = 540°

Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.
To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.
(which is the same as the number of sides).
540° 5 = 108°

There are 108° in each interior angle of a regular pentagon. N=8

Rex's puppy is 5 years younger than his other dog. If the other dog is x years old, what is an expression for the puppy's age?

Can you help me!!!!!!!!!!!!!!!!!!!!!!!!!

Please help!!!!!You just purchased a cellular phone and are trying to decide the best cellular phone company in which to give your business. When you contacted the Talks-A-Lot Company, they were offering a monthly plan of $40 for 600 minutes and $0.35 for each minute exceeding the 600 minutes. In the Sunday paper you see an ad for the Chat-Away Company, which offers a monthly plan of $50 for 600 minutes and $0.10 for each minute exceeding the 600 minutes. How many minutes would you have to talk over and above the 600 minutes for the cost to be the same with both companies and what would be the equal cost?
