Mathematics
2 answers:
Contact [7]3 years ago

Answer and Explanation:

1) Given : The function h is defined by h(y)=2y-7.

To find : The value of h(8)?

Solution :

h(y)=2y-7

Put y=8,

h(8)=2(8)-7

h(8)=16-7

h(8)=9

So, Option C is correct.

2) Given : Equation \frac{7}{8}=\frac{m}{32}

To find : What is the solution to the equation?

Solution :

\frac{7}{8}=\frac{m}{32}

Cross multiply,

7\times 32=m\times 8

224=8m

m=\frac{224}{8}

m=28

So, Option C is correct.

3) Given : Letter 'E'

To find : Which statement is true?

Solution :

Letter 'E' has a horizontal symmetry i.e. the bottom of the letters is a reflection of the top.

i.e. the 'E' has reflection symmetry but no rotational symmetry.

So, Option B is correct.

The letter 'E' has reflection symmetry only.

4) Given : Letter 'Z'

To find : Which statement is true?

Solution :

Letter 'Z' rotated by 180° about particular axis, they remain same.

i.e. the 'Z' has rotational symmetry but not reflection symmetry.

So, Option B is correct.

The letter 'Z' has rotational symmetry only.

5) Given : Letter 'X'

To find : Which statement is true?

Solution :

Letter 'X' has a horizontal symmetry i.e. the bottom of the letters is a reflection of the top.

Letter 'X' has a vertical symmetry i.e. the right side is a reflection of the left.

Letter 'X' rotated by 180° about particular axis, they remain same.

i.e. the 'X' has reflection symmetry and rotational symmetry both.

So, Option A is correct.

The letter 'X' has both reflection and rotation symmetry

Answer(1):

Given that h(y)=2y-7.

h(8) means  plug y=8 into h(y)=2y-7.

h(8)=2*8-7=16-7=9

Hence C) 9 is the final answer.


Answer 2:

(7/8) = (m/32)

to solve for m, we begin by cross multiply

8m=7*32

8m=224

m=28

Hence choice C) 28 is final answer.


Reflection symmetry occurs when a line is drawn to divide a shape in halves so that each half is a reflection of the other.


Rotational symmetry is to check if the given picture is symmetric after some rotation.


Answer 3:

Letter "E" will have

B) the letter has reflection symmetry only

So B) is correct.


Answer 4:

Which statement is true?

Letter "Z" will have

B) the letter has rotation symmetry only

Hence B) is correct.


Answer 5:

Letter "X" will have

A) the letter has both reflection and rotation symmetry

Hence A) is correct.

What do you think are some of the advantages and disadvantages of a capitalist economic system? Do you feel that the advantages
Tcecarenko [31]
Hello!

Advantages of a capitalist economic system:

• Economic growing and expansion.

• Consumer choice (The consumers get to choose what to consume, which leads to better products and services).

• Efficiency of economics (Goods and services based on demand)



Disadvantages of a capitalist economic system:

• Inequality (A small group of people hold most of the wealth)

• There can be a monopoly of power (a specific enterprise is the only supplier of particular commodity)

• Unemployment

• Social benefit ignored. A free market will ignore externalities.

No, I feel the disadvantages outweigh the advantages, because there are more of them.

Lincoln middle school plans to collect more than 2,000 cans of food in a food drive. So far, 668 cans have been collected. WRITE
AURORKA [14]
Let x be the unknown number.

7x + 668 < 2000     => 7x plus 668 is less than 2000

where:
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected.
2000 is the target number of cans.

7x  +  668    <    2000
 <u>       - 668           -668</u>
7x                <   1332
<u>÷7                        ÷7</u>
x                  <    190.30
or
x < 190

To check:

7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000
