Answers

Answer:

x < -2

Step-by-step explanation:

12 - 6x > 24

Subtract 12 from both sides.

-6x > 12

Divide both sides by -6. (When you divide an equality by a negative number, the "greater than" sign becomes a "less than" sign, and vice versa.)

An object’s height is measured in centimeters and in inches. Two rulers, one showing inches, the other showing centimeters. The rulers are aligned at zero. An arrow extends from the one inch mark on the first ruler toward the equivalent length on the other ruler, with the caption, one inch equals two and fifty-four hundredths centimeters. Write an equation that relates the number of centimeters c to the number of inches i. Determine the height in centimeters of a chair that is 32 inches tall. Enter the correct answers in the boxes.

Answers

If an object’s height is measured in centimeters and in inches. the height of the chair in centimeters is 81.28 cm.

How to find the height?

We know that one inch is equivalent to two and fifty-four hundredths centimeters. We can write this as:

1 inch = 2.54 centimeters

To find the equation that relates the number of centimeters c to the number of inches i, we can use this conversion factor:

c = 2.54i

This equation tells us that the number of centimeters is equal to 2.54 times the number of inches.

To find the height in centimeters of a chair that is 32 inches tall, we can plug in i = 32 into the equation above:

c = 2.54i

c = 2.54(32)

c = 81.28

Therefore, the height of the chair in centimeters is 81.28 cm.

Step-by-step explanation:

The inaccuracy in the histogram was discovered by the owner would be:

55-59

60-64

Data Table

The inaccuracy in the number of new clients due to the inapt portrayal of the data between intervals 55-59 and between 60 and 64.

They show the number of new clients as 5 and 6 in these intervals which is incorrect and hence, the histogram becomes wrong.

The actual frequency in these intervals is quite lesser as provided by the data and hence, the shown data is invalid.

Thus, the above responses are correct.

The function g is defined by g(x) = -3x + 2. Which statements are true? Select ALL that apply.
f{-2) is greater than g(-2).
f{-1) is less than g(-1).
f{0) is greater than g(0)
f(1) is less than g(1).
f(2) is greater than g(2).

Answers

Answer:

f{0) is greater than g(0) and f(2) is greater than g(2).

Step-by-step explanation:

f{0) is greater than g(0) = f(0)=8  and g(0)=2

f(2) is greater than g(2) = f(2)=8 and g(2)= -4

The two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

What is the general equation of parabola?

The general equation of a parabola is given as,

[tex]y=a(x-h)^2+k[/tex]

where (h,k) is the coordinate of the vertex of the parabola.

The equation of the parabola with vertex (1,9) can be written as,

[tex]y=a(x-h)^2+k\\\\y=a(x-1)^2+9[/tex]

Now, the value of a can be found by putting one zero of the parabola,

[tex]y=a(4-1)^2+9\\\\0=a(3)^2+9\\\\-9=a(3)^2\\\\-9=a9\\\\a=-1[/tex]

Thus, the equation of the parabola can be written as y=-(x-1)²+9.

A.) The value of the two functions when the value of x is -2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-2)=-(-2-1)^2+9\\\\f(-2)=0[/tex]

[tex]g(x) = -3x + 2\\\\g(-2) = -3(-2) + 2\\\\g(-2)=8[/tex]

Therefore, f(-2) is less than g(-2).

B.) The value of the two functions when the value of x is -1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-1)=-(-1-1)^2+9\\\\f(-2)=5[/tex]

[tex]g(x) = -3x + 2\\\\g(-1) = -3(-1) + 2\\\\g(-1)=5[/tex]

Therefore, f(-1) is equal to g(-1).

C.) The value of the two functions when the value of x is 0 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(0)=-(0-1)^2+9\\\\f(0)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(0) = -3(0) + 2\\\\g(0)=2[/tex]

Therefore, f(0) is greater than g(0).

D.) The value of the two functions when the value of x is 1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(1)=-(1-1)^2+9\\\\f(1)=9[/tex]

[tex]g(x) = -3x + 2\\\\g(1) = -3(1) + 2\\\\g(1)=1[/tex]

Therefore, f(1) is greater than g(1).

E.) The value of the two functions when the value of x is 2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(2)=-(2-1)^2+9\\\\f(2)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(2) = -3(2) + 2\\\\g(2)=-4[/tex]

Therefore, f(2) is greater than g(2).

Thus, the two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).
