9.) 9.40÷4= 2.34 meters

I cant see 10 clearly

11.) No because if you multiply 2×4 you get 8 so .814 wouldn't be reasonable

What is an equation of the line that passes through the points (4, -1)(4,−1) and (8, 5)(8,5)? Put your answer in fully reduced f

matrenka [14]

Answer:

$3x - 2y - 10 = 0 $$

Step-by-step explanation:

When we are to find the equation of the line passing through two points, say $(x_1, y_1)$ and $(x_2, y_2)$ we use two -point form.

The two point form is as follows:

$\frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}$

Here $(x_1 , y_1) = (4, -1)$ and $(x_2 , y_2) = (8, 5)$ .

Therefore we have: $\frac{y + 1}{6} = \frac{x - 4}{4}$

$\implies 2y + 2 = 3x - 12$

Simplifying we get: $3x - 2y - 10 =0$ .

Which polynomial represents a sum of cubes?

bija089 [108]

Answer:

1) The polynomial $8x^3+1$ represents a sum of cubes

2) The polynomial $49x^2-25$ represents a difference of squares

Step-by-step explanation:

1) To find the polynomials represents a sum of cubes :

$8x^3+1$ represents a sum of cubes

For $8x^3+1$

$=2^3x^3+1^3$

$=(2x)^3+1^3$

Therefore $8x^3+1=(2x)^3+1^3$

Therefore $8x^3+1$ represents a sum of cubes

2)To find the polynomials represents a difference of squares :

$49x^2-25$ represents a difference of squares

For $49x^2-25$

$=7^2x^2-5^2$

$=(7x)^2-5^2$

Therefore $49x^2-25=(7x)^2-5^2$

Therefore $49x^2-25$ represents a difference of squares
