Which statement is true for the inequality 2(x - 2) < x + 2?

A). The inequality is only true for numbers greater than -6
B). The inequality is only true for numbers less than 6
C). The inequality is true for all values of x
D). The inequality is never true

Answers

Answer 1

Answer:

Option B

Step-by-step explanation:

2(x - 2) < x + 2

Distribute;

2x - 4 < x + 2

Subtract x from both sides;

x - 4 < 2

Add 4 to both sides;

x < 6

Answer 2

The true statement is The inequality is only true for numbers less than 6

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age≤ 12. This is a real-world example of an inequality.

Given:

2(x - 2) < x + 2

Now solving the inequality

2(x - 2) < x + 2

2x-4 < x+2

2x-x < 2+4

x<6

Hence, The inequality is only true for numbers less than 6.

D: The slope is 3

Step-by-step explanation:

To figure out the slope, which is always a constant, you simply figure out the average displacement using the points we already know. This is described by the equation y2-y1/x2-x1. Let's use the ordered pairs (-3, 2) and (-1, 8) to figure this out.

8-2/-1-(-3) = 6/2 = 3

Another method you could use is to graph the points and figure out how many units y has to go up for every x over, or the "rise over run"

Either way, your slope is 3.

PLEASE HELP ME ,THIS IS HARD ,AND I DON’T UNDERSTAND MATH..

Answers

Answer:

Step-by-step explanation:

divide y by x

in a table and coordinate pair, which is something like (0,4), x always comes first. So, in this table x is the time in seconds and y is the distance in meters. 120/4=30 meters per second. For the second part of the table, since we know what the slope is, or the constant rate of change, 30, we can multiply 30 by 25 which is 750. You can also use the equation y=mx, m is the slope, and x is a point on the coordinate pair. For example, in the second table, y=30(25). For the last part of the table, you can use the same equation. 270=30x. We try to get x alone so we do, 270 divided by 30 which is 9. So a cheetah runs at 270 meters per 9 seconds.

The answer above me is totally correct and has a very good explaination
But I’m still doing this
In the first part it is given time = 4s
Distance = 120m
And we have to calculate it’s speed
We know that speed = Distance/Time
So speed = 120/4
So speed = 30m/s
In second question
Now in the question it is given that cheetah walks at a constant speed
So here time= 25 seconds
Speed= 30m/s (from 1st question)
So distance= speed*time
distance = 30*25
Distance = 750m
Now in third question
Distance is given 270m
Also we know speed = 30m/s
So time = Distance/speed
Time= 270/30
Time = 9 seconds
So answers are
1st part - speed = 30m
2nd part - Distance = 750m
3rd part - Time = 9s
Hope it helps you!

Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.

Answers

Answer:

its 1/3 of the volume of a cyinder with the same base

Step-by-step explanation:

a pyramid has the same policy with prisms of the same base

Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.

The volume of the cone with radius r units and height h units now can be written as,

Volume of the cone = (1/3) × π × r² × h units³

The volume of the cylinder with a radius of r units and the height of h units now can be written as,

Volume of the Cylinder = π × r² × h units³

Taking the ratio of the volume of the cone and the volume of the cylinder,

Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³

Volume of the cone/Volume of the cylinder = 1/3

Volume of the cylinder = 3 × Volume of the cone

Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
