5x+y=2 solve the literal equation for x

Ksenya-84 [330]

Answer:

$\sf \: x = - \frac{1}{5} y + \frac{2}{5}$

Step-by-step explanation:

5x+y=2 solve the literal{It's called linear }equation for x

5x+y=2

Step 1: Add -y to both sides.

5x+y+−y=2+−y

5x=−y+2

Step 2: Divide both sides by 5.

5x/5=−y+2/5

x=−1/5y+2/5

Triangle RST has vertices located at R (2, 3), S (4, 4), and T (5, 0). Part A: Find the length of each side of the triangle. Sho

deff fn [24]

Answer:

(a) Side lengths

$RS = \sqrt{5}$ $ST = \sqrt{17}$ $RT = \sqrt{18}$

(b) Slope

$RS = \frac{1}{2}$ $RT = 1$ $ST = -4$

Step-by-step explanation:

Given

$R = (2,3)$

$S = (4,4)$

$T = (5,0)\\$

Solving (a): Length of each side

This is calculated using distance formula

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

So, we have:

$RS = \sqrt{(4 - 2)^2 + (4 - 3)^2}$

$RS = \sqrt{5}$

$ST = \sqrt{(5 - 4)^2 + (0- 4)^2}$

$ST = \sqrt{17}$

$RT = \sqrt{(5 - 2)^2 + (0 - 3)^2}$

$RT = \sqrt{18}$

Solving (b): The slope of each side

This is calculated using:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

So, we have:

$RS = \frac{4- 3}{4- 2}$

$RS = \frac{1}{2}$

$RT = \frac{0 - 3}{5- 2}$

$RT = \frac{ - 3}{- 3}$

$RT = 1$

$ST = \frac{0 - 4}{5- 4}$

$ST = \frac{- 4}{1}$

$ST = -4$

Solving (c): Classify the triangle

In (a), we have:

$RS = \sqrt{5}$

$ST = \sqrt{17}$

$RT = \sqrt{18}$

None of the sides are equal;

The triangle is scalene

Be-1 where on the boat are registration numbers placed?

Neko [114]

There is a requirement for the Coast Guard that all vessels must be registered with the state in which they'll be operated and their registration numbers must be clearly displayed on the boat.
The sequence of the numbers must be written to both sides of the vessel in a sequence such that it can be read from left to right. The mirror-reading on the vessel is not allowed.
Now the numbers must be Displayed on the front portion of the boat that is the forward half of the vessel.
