Answer:
8x + 16y = 39 and
40x + 8y = 42
Step-by-step explanation:
Let the length of the blue tiles is b inches and that of the white tiles is w inches.
So, given that a row of 8 blue tiles and 16 white tiles has a length of 39 inches and a row of 40 blue tiles and 8 white tiles has a length of 42 inches.
Therefore, we can write the system of linear equations that represents the relationship between the length if a blue tile and a white tile in inches as
8x + 16y = 39 and
40x + 8y = 42 (Answer)
Answer:
x^4
Explanation:
Breakdown x^4 = <u>x</u> · <u>x</u> · <u>x</u> · <u>x</u>
Breakdown x^5 = <u>x</u> · <u>x</u> · <u>x</u> · <u>x</u> · x
Here the common factor is x · x · x · x = x^4
Hence, the greatest common factor of x^4 and x^5 is x^4.
The slopes of WX and YW are opposite reciprocals.

Explanation:
When multiplying and dividing more than two positive and negative numbers, use the Even-Odd Rule: Count the number of negative signs — if you have an even number of negatives, the result is positive, but if you have an odd number of negatives, the result is negative. This problem has just one negative sign
