Answer:
(- 4, - 12 ) , (4, 12 )
Step-by-step explanation:
Given the 2 equations
y = 3x → (1)
y = x² + 3x - 16 → (2)
Substitute y = x² + 3x - 16 into (1)
x² + 3x - 16 = 3x ( subtract 3x from both sides )
x² - 16 = 0 ( add 16 to both sides )
x² = 16 ( take the square root of both sides )
x = ± 
= ± 4
Substitute these values into (1) for corresponding values of y
x = - 4 : y = 3 × - 4 = - 12 ⇒ (- 4, - 12 )
x = 4 : y = 3 × 4 = 12 ⇒ (4, 12 )
The mean is 73.44<span>
</span>You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!
66+81+60+72+79+83+60+92+68 = 661
661 ÷ 9 = 73.44
Step-by-step explanation:
Insufficient information!
however, volume will remain same in both of these figures!
Answer:
76
Step-by-step explanation:
38 multiplied by 2 = 76
2:10 is equivalent. To get the answer you multiply 1 & 2 by their LCM (least common multiple) , which is 2, and that's how you get the answer, and to check to see if it's right just divide by 2 but if you know multiples of 1 and 5 then you could've easily looked at the answer choices to find your answer.
hopefully this helps
