Answers

Answer 1

Answer:

Answer:

x= 25+20y

Step-by-step explanation:

De acuerdo a la situación planteada, la expresión algebraica debe indicar que 25€ que es el valor por la visita más 20€ multiplicado por el número de horas trabajadas es igual al dinero total que se debe pagar. La expresión es:

x= 25+20y, donde

x= valor total a pagar

y= número de horas trabajadas

y - y₁ = m(x - x₁)
y - (-7) = -1¹/₅(x - (-3))
y + 7 = -1¹/₅(x + 3)
y + 7 = -1¹/₅(x) - 1¹/₅(3)
y + 7 = -1¹/₅x - 3³/₅

$m = (y_(2) - y_(1))/(x_(2) - x_(1)) = (-17 - (-2))/(3 - (-9)) = (-17 + 2)/(3 + 9)} = (-15)/(12) = (-5)/(4) = -1(1)/(4)$

y - y₁ = m(x - x₁)
y - (-2) = -1¹/₄(x - (-9))
y + 2 = -1¹/₄(x + 9)
y + 2 = -1¹/₄(x) - 1¹/₄(9)
y + 2 = -1¹/₄x - 11¹/₄
- 2 - 2
y = -1¹/₄x - 13¹/₄

y - y₁ = m(x - x₁)
y - (-3) = ⁻¹/₄(x - 8)
y + 3 = ⁻¹/₄(x) + ¹/₄(8)
y + 3 = ⁻¹/₄x + 2
- 3 - 3
y = ⁻¹/₄x - 1

y - y₁ = m(x - x₁)
y - (-17) = ¹/₂(x - (-6))
y + 17 = ¹/₂(x + 6)
y + 17 = ¹/₂(x) + ¹/₂(6)
y + 17 = ¹/₂x + 3
- 17 - 17
y = ¹/₂x - 14

$m = (y_(2) - y_(1))/(x_(2) - x_(1)) = (-4 - 8)/(-4 - 6) = (-12)/(-10) = (12)/(10) = (6)/(5) = 1(1)/(5)$

y - y₁ = m(x - x₁)
y - 8 = 1¹/₅(x - 6)
y - 8 = 1¹/₅(x) - 1¹/₅(6)
y - 8 = 1¹/₅x - 7¹/₅
+ 8 + 8
y = 1¹/₅x + ⁴/₅

What is the squareroot of 343

Answers

Well, first of all, every positive number has two square roots.
Their digits are the same, but one is positive and one is negative.

The square root of 343 is an irrational number, so it can't ever be
exactly written with digits. As a decimal, it never ends or repeats,
and as a fraction, it can't be written at all.

The positive square root starts out 18.52025... and keeps going forever.

The other square root is the negative of that same number.
When you multiply either of them by itself, the product is close
to 343 . The more decimal places you include, the closer it gets,
but it can never be exactly 343 .
