21. 0.25x - 1.25 - 3x + 2 = -2.75x + 0.75
22. 15/100= 0.15. 0.15•64,000= 9,600. The answer is D.
23. 1,200-300= 9,000. 1,200+300= 15,000. 9,000/15,000= 3/5. 3/5= 0.6. 60% of the building is aboveground.
24. The patterson seems to be the y=18x and when you plug 7 in to the equation, you get 126, not 128, so D is the answer.

Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). What are the coordinates of point B?

erastovalidia [21]

Step-by-step explanation:

Let (x, y) be the coordinates of point B.

(4, 6) => (-2, 4) => (x, y)

We have 2(-2) = 4 + x and 2(4) = 6 + y.

Solving these, we get x = -8 and y = 2.

Hence the coordinates of point B is (-8, 2).

Answer:

$(y,z)=(3,5)\\\\ |(y,z)|=\sqrt{34}$

Step-by-step explanation:

Given y(3, 1), z(0, 4)

-The ordered pair is written by summing their corresponding coordanates as below:

$(y,z)=y(3,1)+z(0,4)\\\\=(3+0,1+4)\\\\=(3,5)$

-We then calculate the magnitude of this ordered pair as following:

$|y,z|=\sqrt{y^2+z^2}\\\\=\sqrt{3^2+5^2}\\\\=\sqrt{34}\\\\\therefore |(y,z)|=\sqrt{34}$

Hence, the magnitude of the ordered pair is $\sqrt{34}$

Find the length of a right triangle if a=6 and b=8

gulaghasi [49]

Answer:

10

Step-by-step explanation:

a^2 + b^2 = c^2

6^2 + 8^2 = c^2

36 + 64 = 100

Square root of 100 is 10

a=6 b=8 c=10

I'm so sorry if I got this wrong.
