4 0

For the first question you multiply 4 by 2x and then -1, getting 8x - 4. 3 multiply by 2x and then +5 gives you 6x + 15. 8x +6x = 14x; -4 + 15 = 11. The answer to the first question would be 14x + 11.

For the second question:
1. 3
2. 1
3. -1
4. -3
The tenth term. -15

4(2x - 1) + 3(2x + 5)
8x - 4 + 6x + 15
14x + 11 (the answer).

3, 1, -1, -3, -15 (the 10th term)
Let me know if you need working on this part :)

To find m ( slope) we'll use the Slope Formula:

$\boxed{\sf{Slope\:(m)}=\cfrac{y_2-y_1}{x_2-x_1}}$

<u>Subtract the numbers:-</u>

$\sf 7. \:m=\cfrac{4-2}{6-5} =\boxed{2}$

_______________

$\sf 8.\: m=\cfrac{-1-3}{2-6} =\boxed{1}$

_______________

$\sf 9.\: m=\cfrac{-4-(-2)}{3-1} =\boxed{-1}$

_______________

$\sf 10.\: m=\cfrac{0-3}{0-(-3)} =\boxed{-1}$

_______________

$\sf 11.\:m=\cfrac{4-2}{3-1} =\boxed{1}$

_______________

$\sf 12.\: m=\cfrac{1-7}{2-5} =\boxed{2}$

_______________

$\sf 13.\:m=\cfrac{11-9}{1-(-4)} =\boxed{\frac{2}{5}}$

_______________

$\sf 14.\:m=\cfrac{2-3}{3-5} =\boxed{\frac{1}{2}}$

_______________

$\sf 15.\: m=\cfrac{11-5}{2-9} =\boxed{-\frac{6}{7}}$

_______________

$\sf 16.\: m=\cfrac{-7-\left(-6\right)}{8-13}=\boxed{\frac{1}{5}}$

_______________

$\sf 17.\: m=\cfrac{4-4}{6-1} =\boxed{0}$

The measure of two complementary angles are (4x + 3)° and (x + 4)°. What is the measure of the larger angle?

Aleksandr-060686 [28]

Answer:

69.4 degrees.

Step-by-step explanation:

Complementary angles add up to 90 degrees so we have the equation:

4x + 3 + x + 4 = 90

5x + 7 = 90

5x = 83

x = 16.6

The larger angle = 4x + 3

= 4(16.6) + 3

= 69.4 degrees (answer).

In the figure to the right, AB=7 1/2m, BC=2 1/4 m, and DE=1 1/4m. Find the perimeter of the figure if all angles are right.

Eduardwww [97]

Answer:

22 meters

Step-by-step explanation:

What we know:

Side AB is 7 1/2 m long, Side BC is 2 1/4 m long, and Side DE is 1 1/4 m long.

Saying Sides AH and FG are the same as Sides DE and BC respectively, we can add another 3 1/2 m to the perimeter.

If CD, EF and GH are each 1/3 of AB, then 7 1/2 is added again.

7.5 + (2.5 * 3) * (2.25 * 2) + (1.25 * 2)

7.5 + 7.5 + 4.5 + 2.5

15 + 7

The perimeter is 22 meters.
