What is the classification for this polynomial? X2y+3x3

Answer:

-9

Step-by-step explanation:

-7x+10x^3-9x^5+3x^2+3

We need to write the terms from highest power to smallest power

-9x^5+10x^3+3x^2-7x+3

The leading coefficient is the number in front of the highest power

-9

Answer:

An annual increase of 1000 means that the number by which the population increases is constant, which means that the population cannot be modeled with an exponential growth function, it is modeled by a linear growth function.

Step-by-step explanation:

Linear growth:

The number by which it increases is constant.

Exponential growth:

The rate which it increases is constant, that is, a proportion of population.

Annual increase of 1,000.

An annual increase of 1000 means that the number by which the population increases is constant, which means that the population cannot be modeled with an exponential growth function, it is modeled by a linear growth function.

Answer:

x=52.5

Step-by-step explanation:

Since ABCD is a parallelogram, B= ADC. So angle ADC is 105. Next since ED=AD, angle EAD=angle AED=x and ADE=75. So 2x+75=180, 2x=105, x=105/2

In parallelogram ABCD, m∠B = 105° then the value of x = 52.5

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Since ED ≈ AD,

∆AED is an isosceles triangle where ∠EAD and ∠AED has the same angle measurement

Now, ∠B = 105°, since ABCD is a parallelogram,

∠B = ∠D

∠ADC = 105°

∠ADE = 180°-105° = 75°

Now, ∠EAD + ∠AED+ ∠ADE = 180°

∠AED+∠AED+∠ADE = 180°

x+x+75°=180°

2x=180+75°

2x = 105°

x = 52.5°

Answer:

the dad is 60 im not sure about the son

Step-by-step explanation:

Answer:

x = y = 104°

Step-by-step explanation:

The sum of the interior angles = 360°

The opposite angles x and y are congruent , that is y = x , then

92 + 60 + x + x = 360

152 + 2x = 360 ( subtract 152 from both sides )

2x = 208 ( divide both sides by 2 )

x = 104

Then

x = y = 104°

Answer:

33

Step-by-step explanation:

Pamela-x

Jiri-x+14

x+x+14=52

2x=52-14

2x=38

x=19-Pamela

19+14=33-Jiri

check: 19+33=52

Answer: Jiri is 33 years old, and Pam is 19.

Step-by-step explanation:

Let's put Jiri as x, and Pam as y. We know that Pam's and Jiri's age =52. Pam is 14 years younger than Jiri(x)

You can model the situation by two equations:

y=x-14

x+y=52

Substitute y into second equation

x+x-14=52

2x=66

x=33

Jiri is 33

and back to the first equation

y=33-14=19, Pamela's age.

Answer:

3/2

Step-by-step explanation:

the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

so, when we have 2 points, we can look at the difference of the x and y coordinates. y difference / x difference is the slope.

going from (3, 4) to (5, 7) changes x by +2 and y by +3.

so, the slope of the line is 3/2

Step-by-step explanation:

Let the mystery number be x

Equation:

60 - 4x = 8x + 72

Subtract 60 from both sides

-4x = 8x + 12

Subtract 8x from both sides

-12x = 12

x = -1

Answer:

"The sum of two numbers is 17" <- that's our first equation. Sum means we're going to add. "two numbers" - well, we don't know what they are, so we can use x and y. (Note: x and y are just placeholders. You can use ANY placeholder as long as you keep it consistent with the second equations. x and y just mean "some number". We're going to work to find those numbers)

So for our first equation, we have two numbers being added together. So we can just write that as:

x+ y = 17

For the second equation:

"Three times one number increased by 5 is the same as twice the other number decreased by 4"

We have to work to process what is being asked. “Three times one number increased by 5”. So we know we are multiplying 3 to one of our numbers and increasing it (adding it) by 5.

So this part can be written as 3x+5

“Is the same as” just means “equal to” 

“Twice the other number decreased by 4”. So twice, means two times and “decreased by four” just tells us to subtract four.  So this part can be written as:

2y-4

Now we need to put this second equation together.

3x+5=2y-4.

So now we have our two equations:

x+y = 17

3x+5 = 2y-4

We have a few ways of solving this. We can use substitution, elimination, or graphing. I’m going to use substitution for this one.

So for substitution, we need to take one of two equations and solve for a single variable. So I’m going to take our first equation and solve for y.

x+y=17

-x.   -x

y= -x+17

Now I’m going to put “-x+17” in for the “y” in the second equations.

3x+5=2y-4

3x+5 = 2 (-x+17) - 4.  (Now distribute)

3x+5 = -2x + 34 - 4. (Now simplify)

3x+5 = - 2x + 30. (Now we need to get the x to one side)

+2x +2x

5x+5=30

 -5.  -5

5x = 25

X = 5

Now we can take the first equation and put 5 in for x to solve for y

x+y = 17

5 + y = 17

-5    -5

y= -12

So our x is 5 and our y is 12.
