5)Ten less than 6 times a number is greater than or equal to 2 more than twice the number.

Answers

Answer 1

Answer:

6n-10 >= 2+2x2

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

6x - 10 ≥ 2x + 2 Subtract 2x from both sides

6x-2x - 10 ≥ 2x - 2x +2 Combine

4x - 10 ≥ 2 Add 10 to both sides

4x - 10+ 10 ≥ 2 + 10 Combine

4x ≥ 12 Divide by 4

4x/4 ≥ 12/4 Combine

x ≥ 3

What is the equation of the line that passes through the point (−3,4) and has a slope of 1 ?

Answers

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1, thus

y = x + c ← is the partial equation

To find c substitute (- 3, 4) into the partial equation

4 = - 3 + c ⇒ c = 4 + 3 = 7

y = x + 7 ← equation of line

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

We have following equation to find the point-slope form of the linear functions.

[tex]y - y(0) = m \times ( \: x - x(0) \:) [/tex]

In which :

[tex]y(0) = y \: \: given \: \: point = 4[/tex]

[tex]x(0) = x \: \: given \: \: point = - 3[/tex]

[tex]m = slope = 1[/tex]

Now just need to put the coordinates and the slope in the above equation.

[tex]y - 4 = 1 \times ( \: x - ( - 3) \: )[/tex]

[tex]y - 4 = x + 3[/tex]

Add sides 4

[tex]y - 4 + 4 = x + 3 + 4[/tex]

[tex]y = x + 7[/tex]

Done...

A line passes through the point (10,2) and has a slope of 1/2. Write an equation in slope-intercept form for this line.

Answers

Answer:

Step-by-step explanation:

y - 2 = 1/2(x - 10)

y - 2 = 1/2x - 5

y = 1/2x - 3

Answer:

Step-by-step explanation:

You can read the slope right away.

y = 0.5x + b 1/2 = 0.5

The point will determine the y intercept

2 = 0.5*10 + b

2 = 5 + b

2-5 = b

b = - 3

The line is y = 0.5x - 3

Al sumar su doble, su mitad y 15 se obtiene 99.

Answers

Answer:x = numero

2x= doble

x/2= mitad

sumamos todo : x+2x+x/2+15=99

7x/2= 99-15

7x= 84(2)

x=168/7

x=24

comprueba sumando 24+48+12+15=99 suerte!!!

Step-by-step explanation:

The value of the unknown number is 33.6

Let the unknown number be "x"

The half of the number is 0.5x

Double of the number is expressed as 2x

Adding this functions together and 15 and equating to 99 will give;

0.5x + 2x + 15 =99

Solve for x

2.5x = 99 - 15

2.5x = 84

x = 84/2.5

x = 33.6

Hence the value of the unknown number is 33.6
