Answer:

This is the sum --->  4x^2y + 4xy^2 - 1

Step-by-step explanation:

(3x^2y+4xy^2-2y^3+3) + (x^2y+2y^3-4)

(remove the parenthesis)

= 3x^2y + 4xy^2 - 2y^3 + 3 + x^2y + 2y^3 - 4    

(now, group the like terms)

= -2y^3 + 2y^3 + 4xy^2 + 3x^2y + x^2y + 3 - 4  

(add the elements you think are alike or similar)

= -2y^3 + 2y^3 + 4xy^2 + 4x^2y + 3 - 4              

=  4xy^2 + 4x^2y + 3 - 4  

= 4xy^2 + 4x^2y - 1

Answer:

the sum is  4x^2y + 4xy^2 - 1

Answer:

B' = {1, 3, 5, 6, 7}

Step-by-step explanation:

U = {1, 2, 3, 4, 5, 6, 7, 8}

B = {2, 4, 8}

So the complement  ( the set of elements in U but not in B) is:

B' = {1, 3, 5,  6, 7}

Answer:

Volume = Length × Width × Height

Answer:

154 2/3 m²

Step-by-step explanation:

14 1/2 x 10 2/3

First, make the mixed numbers into improper fractions:

29/2 x 32/3

Simlify by cross cancelling if you can:

29/1 x 16/3

Then, multiply:

29/1 x 16/3 = 29 x 16/1 x 3 = 464/3

Finally, turn the new improper fraction into a simplified mixed number:

464/3 = 154 2/3

The area is 154 2/3 m²

Answer:

-1

Step-by-step explanation:

Plug in all of the numbers for x. 1 is -5<-5 and -1 is -15<-5

The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Given that:

[tex]R(t) = t^2 + 7t + 159[/tex]

[tex]c(t) = t^2 + 131[/tex]

The profit function P(t) is calculated as follows:

[tex]P(t) = R(t) - c(t)[/tex]

So, we have:

[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]

Open brackets

[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]

Collect like terms

[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]

[tex]P(t) = 7t + 28[/tex]

Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Step-by-step explanation:

Answer:

b) division.

Answer:

Ratio should be equal so ratio is 3:3

The ratio of the triangles to circles in the diagram below would be; 1: 1

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained.

Thus, there are three circles and three triangles shown in the figure.

Therefore, the ratio will be;

three circles: three triangle

3 : 3

1: 1

Hence, the ratio of the triangles to circles in the diagram below would be; 1: 1

25 . f (-6) = 7

26 . f (0) = -2

27 . x = 2

28 . x = -4

Answer:

No

Step-by-step explanation:

Given

- 2x + 4 = 18

note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2

However , the first step is to isolate the term in x by subtracting 4 from both sides.

- 2x = 18 - 4 = 14 ( divide both sides by - 2 )

x = - 7

Answer:

[tex]v=s-u+t[/tex]

Step-by-step explanation:

Hi there!

[tex]s=u-t+v[/tex]

Our goal is to isolate v on one side of the equal sign.

Subtract u from both sides:

[tex]s-u=u-t+v-u\\s-u=-t+v[/tex]

Add t to both sides to isolate v:

[tex]s-u+t=-t+v+t\\s-u+t=v\\v=s-u+t[/tex]

Answer:

  8/5 = 1.6

Step-by-step explanation:

It looks like the line crosses grid points (-4, -4) and (1, 4). This means the slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -(-4))/(1 -(-4)) = 8/5 = 1.6

The slope of the line seems to be about 8/5, or 1.6.
