What is the equation of the line that passes through (3.-5) and is parallel to 5x - 3y = 15?​

Answers

y = 5/3x - 10

Step-by-step explanation:

[tex]5x - 3y = 15\\-3y = -5x + 15\\y = 5/3x - 5[/tex]

that means the slope of the new line also has to be 5/3 because parallel lines have the same slope.

put it in point-slope form:

y - -5 = 5/3(x - 3)

y + 5 = 5/3x - 5

with working pls​

Answers

Answer:

33+12t−21t^2

Step-by-step explanation:

(2t-7)²-(5t-4)²

Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (2t-7)².

4t^2−28t+49−(5t-4)²

Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (5t-4)².

4t^2−28t+49−(25t^2−40t+16)

To find the opposite of 25t^2

−40t+16, find the opposite of each term.

4t^2−28t+49−25t^2−40t+16

Combine 4t^2  and −25t^2  to get −21t^2.

−21t^2−28t+49+40t−16

Combine −28t and 40t to get 12t.

−21t^2+12t+49−16

Subtract 16 from 49 to get 33.

−21t^2+12t+33

Swap terms to the left side.

33+12t−21t^2

a brick measures
l= 15 cm
b= 8 cm
h= 5 cm
how many bricks will be used to make a wall of length=15 m, breath=10 m and height=8m

Answers

Answer:

2000000 bricks

Step-by-step explanation:

The computation of the number of bricks to be used is shown below:

The Volume of brick is

= (15 × 8 × 5)cm^3

= 600 cm^3

And, the Volume of wall is

= (1500 × 1000 × 800)cm^3

= 1200000000 cm^3

Now Bricks needed is

= 1200000000 cm^3 ÷ 600cm^3

= 2000000 bricks

A is correct! Have a good day!

0.81382 is a rational number because it is a terminating decimal.

What is rational number?

A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero, and also whose behavior is known.

What is irrational number?

An irrational number is a type of real number which cannot be represented as a simple fraction and also whose behavior is not known.

According to the given question.

We have a number 0.81382

The above number is not repeating but terminating.

Therefore, we can say that the above number is rational because it is a terminating decimal.

Hence, 0.81382 is a rational number because it is a terminating decimal.

if SP =210 profit percent =5% CP = X , find CP​

Answers

Step-by-step explanation:

Given

SP = 210

profit percent (p%) = 5%

CP = X = ?

We know

Cost price (CP)

[tex] = \frac{sp \: \times 100}{100 + p\%} \\ = \frac{210 \times 100}{100 + 5} \\ = \frac{21000}{105} \\ = 200[/tex]

hope it helps :)❤

Or in another way

Let the cost price be x then

Profit amount

= 5 % of CP

= 5/100 * x

= x / 20

Selling Price (SP)

210 = CP + Profit amount

210 = x + x / 20

210 = ( 20x + x) / 20

210 * 20 = 21x

4200 = 21x

x = 4200 / 21

x = 200

Therefore CP = 200

Angle A = 90 - 53 = 37°

Therefore,

the correct equation would be

tan(A°) = opposite/adjacent
