Which equation represents the line passing through the points (3, 2) and (–9, 6)?

1 answer:

4 0

(3,2),(-9,6)
slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points...(3,2)....x = 3 and y = 2
now we sub into the formula and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur equation is : y = -1/3x + 3 <==

Find the volume of the square pyramid showing. round to the nearest 10th if necessary

solong [7]

The volume of a square pyramid is (1/3)(area of base)(height of pyramid).

Here the area of the base is (10 ft)^2 = 100 ft^2.

13 ft is the height of one of the triangular sides, but not the height of the pyramid. To find the latter, draw another triangle whose upper vertex is connected to the middle of one of the four equal sides of the base by a diagonal of length 13 ft. That "middle" is 5 units straight down from the upper vertex. Thus, you have a triangle with known hypotenuse (13 ft) and known opposite side 5 feet (half of 10 ft). What is the height of the pyramid?
To find this, use the Pyth. Thm.: (5 ft)^2 + y^2 = (13 ft)^2. y = 12 ft.

Then the vol. of the pyramid is (1/3)(area of base)(height of pyramid) =
(1/3)(100 ft^2)(12 ft) = 400 ft^3 (answer)

Solve the system of equations algebraically.

andrew11 [14]

Answer: d. (17, 20)

Step-by-step explanation:

We have the following system of equations:

$x-3y=8$ (1)

$5x-4y=5$ (2)

Isolating $x$ from (1):

$x=\frac{8+3y}{4}$ (3)

Substituting (3) in (2):

$5(\frac{8+3y}{4})-4y=5$ (4)

Isolating $y$ :

$\frac{40}{4}+\frac{15 y}{4}-4y=5$ (5)

$10-5=4y-\frac{15 y}{4}$ (6)

$y=20$ (7)

Substituting (7) in (1):

$x-3(20)=8$ (8)

Isolating $x$ :

$x=17$ (9)

Hence, the correct option is d. (17, 20)

Twice the product of 3and a number exceeds the sum of the number and 80 by 10.what is the number?

Hatshy [7]

First, create an equation with the criteria given.

If we let x be your number,
$2(3x) = 80 + x + 10$
( $2(3x)$ is twice the product of 3 and x, and if it exceeds $x+80$ by 10, then we add 10 to $x+80$ to make the two sides of the equation equal.)

Now, solve for $x$ .

$6x=90+x \\ 5x=90 \\ x=18$
