Step-by-step explanation:

Hey there!

The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.

Note: use one point formula for finding the equation.

$(y - y1) = m(x - x1)$

Put all values.

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

Simplify it.

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

$(y + 3) = - \frac{3}{4} x + 6$

$y = - \frac{3}{4} x + 6 - 3$

$y = - \frac{3}{4} x + 3$

Therefore, the equation is; y = -3/4x+3.

Hope it helps...

From the diagram below, if the tree is 34 ft. tall, and the angle of elevation from point B to the top of the tree is 26 °, find

lana66690 [7]

Given the height of the tree and the angle of elevation from point B, the distance between the tree is from point B is approximately 70ft.

<h3>What is the distance between the tree and point B?</h3>

Given the data in the question;

Height of tree opposite angle of elevation = 34ft
Angle of elevation θ = 26°
Distance between tree and point B| Adjacent = ?

Since the scenario form a right angle triangle, we use trig ratio.

tanθ = Opposite / Adjacent

tan( 26° ) = 34ft / x

We solve for x
x = 34ft / tan( 26° )

x = 34ft / 0.4877

x = 70ft

Given the height of the tree and the angle of elevation from point B, the distance between the tree is from point B is approximately 70ft.

Which value if x makes this proportional true? 14/20=56/x A.x=62 B.x=70 C.x=80 D.x=100

Leya [2.2K]

<h3>Answer: C) x = 80</h3>

==================================================

Work Shown:

Let's cross multiply to get the following

14/20 = 56/x

14*x = 20*56

14x = 1120

x = 1120/14

x = 80

-------------------

As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.

Answer:

512 ounces

Step-by-step explanation:

there are 16 ounces in a pound so you multiply 4 x 16= 64 ounces for the 4 pounds. Since Dustin had 8 pots you multiply 64 x 8= 512 ounces.
