2(1 – x) > 2x HELP ASAP!!! I CANT FIGURE THIS OUT

Answers

Answer 1
Answer:  x < 1/2

This is the same as saying x < 0.5 since 1/2 = 0.5

====================================================

Work Shown:

2(1-x) > 2x

2*1 + 2*(-x) > 2x ..... distribute

2 - 2x > 2x

2 > 2x+2x .... adding 2x to both sides

2 > 4x

4x < 2 ..... flip both sides; flip the inequality sign

x < 2/4 ..... dividing both sides by 4; see note below

x < 1/2

Note: We do not flip the inequality sign here because we are dividing both sides by a positive value. The inequality sign would only flip if you divide both sides by a negative number.

Find the value of the missing Angles:

Answers

Answer:

Angle 1 is 58 and Angle 2 is 32 because all triangles equal to 180 and where the lines bisect creates a 90 degree angle in each triangle. Add 90 and 32 together, then minus 122 from 180 and you get angle 1 and the angle across from angle 1. For angle 2, add 58 and 90, then subtract that from 180. You'll end up getting 32

Step-by-step explanation:

Zachary is standing in a stadium and has the option of running up a staircase or down a staircase for exercise.

The function f(x)= 1/25(∣4x∣+2x) will determine how many calories Zachary will burn if he runs up x steps. Use a negative value for x if he runs down the stairs. What does the domain represent in this function?

Answers

Answer:

R(All real numbers)

Step-by-step explanation:

We are given that the calories burn in x steps of running is given by

[tex]f(x)=\frac{1}{25}(|4x|+2x)[/tex]

We have to find the domain of this function.

We know that

|x|=[tex]x, x\geq 0[/tex]

    -x, x<0

Therefore, the function

[tex]f(x)=\frac{1}{25}(4x+2x) ,x\geq 0[/tex]

             [tex]\frac{1}{25}(-4x+2x) ,x<0[/tex]

[tex]f(x)=\frac{1}{25}(6x), x\geq 0[/tex]    

            [tex]\frac{1}{25}(-2x), x<0[/tex]

The function is defined for all values of x.

Therefore, the domain of f(x)=All real numbers (R)

Answers

Answer:

Step-by-step explanation:

20/1.6=12.5

12.5-3.5=9

9=b

Answer:
9

Explanation:

First you multiply 1.6 by b and 3.5.
1.6b+5.6=20

Then you move everything besides b over to one side and change the sign.
1.6b=20-5.6

Next you subtract 20 by 5.6.
20-5.6=14.4

Finally you divide 1.6 by both sides.
b=14.4/1.6
b=9

Answers

Answer:

y=-x+3 follows the same equation as y=mx+b

3 is b, and b is the y-intercept. The y intercept is where the line crosses on the y axis,  and -x is is m, which is the slope. However since its a variable, its point is on the same number as positive three on the y axis, so then its 3 on the x axis.

a globe that is 3 ft tall casts a shadow that is 7 ft long.find the length of the shadow that a 6ft woman casts​

Answers

I believe 14ft. If you look at the ratio 3:7 So when the woman's shadow is 6ft she has a 14ft shadow. Since 3x2=6 : 7x2=14

The length of the shadow of 6 ft woman will be equal to 14 ft.

What is an arithmetic operation?

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.

Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given information in the question,

Size of the globe = 3 ft.

Size of the shadow of the globe = 7 ft

Height of woman = 6 ft

Let the shadow of woman = x ft.

3 ft = 7 ft

6ft = x ft

Use cross-multiplication method,

x = (6 × 7)/3

x = 2 × 7

x = 14 ft.

In what ways are linear functions and exponential functions the same? In what ways are they different? How can they be used to model real world situations?

Answers

Answer:

In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier- it will never be the same but there will be a pattern. Exponential functions are used in real world situations such as bacterial growth/decay, population growth/decline, and compound interest. Linear functions/equations can be used for comparing rates of pay. Hope this helped!
