Mathematics
1 answer:
Julli [10]4 years ago
4 0

Answer:

Step-by-step explanation:

3x - 4y = 9...........(1)

2x + 8y = 6..........(2)

Multiply (1) by 2 and (2) by 3

6x - 8y = 18.........(3)

6x + 24y = 18......(4)

Subtracting (3) from (4)

24y - (-8y) = 18 - 18

24y + 8y = 0

32y = 0

y = 0/32

y = 0

Substituting y = 0 into (1)

3y - 4y = 9

3y - 4(0) = 9

3y = 9

y = 9/3

y = 3

15. What is the algebraic notation of a figure is Translated 8<br> units left and 2 units up?
sasho [114]

Answer:

Please check the explanation.

Step-by-step explanation:

When a figure is translated with 8 units left and 2 units up, it means the translated figure can be obtained by subtracting 8 units from the x-axis and adding 2 units to the y-axis.

For example, if a point P(0, 0) is translated with 8 units left and 2 units up, the new position of the point will be:

(x, y) → (x-8, y+2)

P(0, 0) → P'(0-8, 0+2) = P'(-8, 2)

Thus, the new location of the image of point P will be: P'(-8, 2)

Therefore, option (a) is the correction answer.

<em>                                           </em><u><em>FOR QUESTION 16</em></u>

As the algebraic notation of a figure is Translated 2 units right and 5 units up.

Translating 'a' units right mean, we need to add 'a' units to the x-axis.

Thus, the rule will be:

(x, y) → (x+2, y+5)

Therefore, option (b) is correct.

Explain the properties of exponents with examples of your own
11Alexandr11 [23.1K]
This is an example of the quotient of powers property and tells us that when you divide powers with the same base you just have to subtract the exponents. When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1.
