Answer:

3 ≥ x

Step-by-step explanation:

2(4+2x)≥5x+5 | Given Expression

8 + 4x ≥ 5x + 5 | Distributive Property

^(multiply the terms on the inside of the parenthesis by 2)

8 ≥ 1x + 5 | Subtraction Property of Equality

^(subtract 4x from both sides)

3 ≥ x | Subtraction PoE

^(subtract 5 from both sides)

Answer:

x ≤ 3

Step-by-step explanation:

2(4+2x) ≥ 5x+5 (by PEDMAS, expand parentheses first)

4(2) + 2x(2) ≥ 5x + 5

8 + 4x ≥ 5x + 5 (subtract 8 from each side)

4x ≥ 5x + 5 - 8

4x ≥ 5x - 3 (subtract 5x from both sides)

4x -5x ≥ - 3

-x ≥ - 3 (multiply both sides by -1, remember to flip the inequality when multiplying both sides by a negative number)

x ≤ 3

If the mass of your father is 70kg, what is his weight (N)?

Lana71 [14]

Answer:

686.7 N

Step-by-step explanation:

mass the person is 70 kg , which is constant for the entire universe.Although weight of the person is depends upon the gravity of the planet on which he resides

W= mg

m= mass W= wight and g= Acceleration due to gravity of the planet which 9.81 m/sec^2 on earth.

therefore weight W = 70×9.81 = 686.7 N

Hence the weight of the father will be 686.7 N

Put the following equation of a line into slope-intercept form, simplifying all

kolbaska11 [484]

Slope-intercept form: y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

To put this into slope-intercept form, you need to isolate/get the variable "y" by itself in the equation:

8x - 6y = 6 Subtract 8x on both sides

8x - 8x - 6y = 6 - 8x

-6y = -8x + 6 Divide -6 on both sides to get "y" by itself

$\frac{-6y}{-6} =\frac{-8x+6}{-6}$

$y=\frac{-8}{-6} x+\frac{6}{-6}$

$y=\frac{4}{3}x -1$
