Answer:
Step-by-step explanation:
- x² - 16 = 0
- x² = 16
- x = √16
- x = ± 4
Answer:
Solution: (-4, 2), x= -4 and y =2
Step-by-step explanation:
-8x - y = 30
-2y = x
Substitute for x
-8*(-2y) - y = 30
16y - y = 30
15y = 30
y = 30/15 = 2
Then x = -2y = -2*(2) = -4
Solution: (-4, 2), x= -4 and y =2
Answer:
30 meters^3
Step-by-step explanation:
volume is l x w x h
so the formula would be 5x3x2
which is 15x2
therefore the answer is 30
Answer: d=3
Step-by-step explanation: 3 times 3 is 9
9 times 3 is 27

Answer and explanation:
Since x = number of true or false questions correct
And y = number of multiple choice questions correct
And each question for x =2 points
each question for y=3 points
since she then needs a total score of more than 93 to pass, we add up total correct questions and
Inequality equation = 2x +3y >93
