Answer:
<u>B. x = -7, y = -8</u>
Step-by-step explanation:
<u>Equation 1</u> : -7x + 6y = 1
<u>Equation 2</u> : -4x + 3y = 4
<u>Multiply Equation 2 by 2.</u>
- 2(-4x + 3y) = 4(2)
- <u>Equation 3</u> : -8x + 6y = 8
<u />
<u>Subtract Equation 3 from Equation 1.</u>
- -7x + 6y - (-8x + 6y) = 1 - 8
- -7x + 8x + 6y - 6y = -7
- x = -7
<u>Substitute x in Equation 1.</u>
- -7(-7) + 6y = 1
- 6y = -48
- y = -8
<u>Solution</u>
- <u>x = -7, y = -8</u>
- <u>Option B</u>
Answer:
B) 10
Step-by-step explanation:
The range of a data set is found by subtracting the smallest term given in the set from the largest term given in the set. First, set the terms in order from least to greatest:
5 , 7 , 10 , 11 , 12 , 13 , 15 , 15, 15 ,
Subtract the greatest (15) with the least (5): 15 - 5 = 10
