Answer:
15
Step-by-step explanation:
we have to divide a value of y by a value of x
(15: 1) = 15
we can check this result by do other tries.
(30:2) = 15
(45:3) = 15
(60:4) = 15
(6r-1)(-88-3)
Multiply the two brackets together
(6r)(-88)=-528r
(6r)(-3)=18r
(-1)(-88)=88
(-1)(-3)=3
-528r-18r+88+3 ( combine like terms)
Answer: -546r+91
Equations
• x² + y = 0 ... (1)
• x² - 4x - y = 0 ... (2)
Answer -> (x, y) = (2, -4)
Step-by-step solution:
From equation 2,
-> y = x² - 4x ... (3)
• Substitute y into equation 1
-> x² + (x² - 4x) = 0
-> 2x² - 4x = 0
-> 2x² = 4x
-> x²/x = 4/2
-> x = 2
• Put x = 2 in equation 3
-> y = (2)² - 4(2)
-> y = 4 - 8
-> y = -4
The average would be -3. You add all the low temps up and get -15 then you divide it by the amount which was 5 temps... And get -3.
