Which numbers multiply to 50 and add to 6

Answers

Answer 1

Answer: xy = 50
x + y = 6

$xy = 50$
$(xy)/(x) = (50)/(x)$
$y = (50)/(x)$

$x + y = 6$
$x + (50)/(x) = 6$
$(x^(2))/(x) + (50)/(x) = 6$
$(x^(2) + 50)/(x) = 6$
$x^(2) + 50 = 6x$
$x^(2) - 6x + 50 = 0$
$x = \frac{-(-6) \± \sqrt{(-6)^(2) - 4(1)(50)}}{2(1)}$
$x = (6 \± √(36 - 100))/(2)$
$x = (6 \± √(-64))/(2)$
$x = (6 \± 8i)/(2)$
$x = 3 \± 4i$
$x = 3 + 4i$ $or$ $x = 3 - 4i$

x + y = 6
  3 + 4i + y = 6
- (3 + 4i) - (3 + 4i)
y = 3 - 4i
(x, y) = (3 + 4i, 3 - 4i)

or
  x + y = 6
  3 - 4i + y = 6
- (3 - 4i) - (3 - 4i)
y = 3 + 4i
  (x, y) = (3 - 4i, 3 + 4i)

(x, y) = (3 ± 4i, 3 ± 4i)

The two numbers that multiply to 50 and add up to 6 are 3 ± 4i.

D= $\sqrt{(8-(-3))^(2)+(-7-4)^(2)}$
D= $\sqrt{(11)^(2)+(-11)^(2)}$

What is the domain and range of the following? (1,5) (-2,4) (-3,0) (-6,2)

Answers

Domain: {1, -2, -3, -6}

Range: {5, 4, 0, 2}

im not 100% sure but Im pretty sure it’s that

I know someone answered but I’m going to say why the answer is the answer.

When it is asking for the domains it is asking for the x values. (1, -2, -3, -6)

When it is asking for the ranges it is asking for the y values. (5, 4, 0, 2)

Tim works part time at a retail store. His salary varies directly by the number of hours worked. Last week he arned $99.45 for 13 hours of work. This week he earned $160.65. Write and solve an equation that represents this scenario.

Answers

99.45/13=$7.64 This is Tim's hourly wage.

So to find out how many hours he worked this week you would write the equation:
160.65=7.64•h

• means multiplication
H=hours worked.

You should solve it by dividing 160.65/7.64=H (hours worked).

Answer

$45.25

In order to solve the equation −3x + 6 = 5, the first step is to (1 point)add 6 to both sides
divide by 5 on both sides
subtract 6 from both sides
multiply by 5 on both sides

Answers

Answer:

Option (C) is correct.

To solve the given equation −3x + 6 = 5,the first step is to subtract 6 from both sides.

Step-by-step explanation:

Given : equation −3x + 6 = 5

We have to solve for x in the equation −3x + 6 = 5.

Consider, the equation −3x + 6 = 5

First step: Subtract 6 both side , we get

⇒ −3x + 6 - 6 = 5 - 6

⇒ −3x = -1

Second step : Divide both side by -3 , we get,

$x=(1)/(3)$

Thus, option (C) is correct.

To solve the given equation −3x + 6 = 5,the first step is to subtract 6 from both sides

−3x + 6 = 5 | -6 (first step is: "subtract 6 from both sides" )

-3x = 5-6
-3x = -1 | /(-3) (second step is: "divide by (-3) on both sides" )

$\displaystyle \n x = (-1)/(-3) = \boxed{(1)/(3) }$

What is the inquality

Answers

Answer:

Step-by-step explanation:

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. ... An equation or an inequality that contains at least one variable is called an open sentence.

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)

Difference in size,degree,circumstances etc lack of equality.

Which expression is equivalent to 10 - 810−810, minus, 8?

Answers

Answer:

10+(-8)

Step-by-step explanation:

Final answer:

The expression 10 - 8 - 810 is equivalent to -808.

Explanation:

The expression 10 - 8 - 810 is equivalent to subtracting 8 from 10 and then subtracting 810. The order of operations states that subtraction should be done from left to right, so we first subtract 8 from 10 to get 2. Then we subtract 810 from 2 to get -808.
