Answer:
Step-by-step explanation:
9(y = 1/9x + 5)
9y = x + 45
-x + 9y = 45
x - 9y = -45
Answer:
(8,5)
Step-by-step explanation:
5x - 2y = 30
coordinates are (x,y) so you plug in 8 for x and solve for y
5(8) - 2y = 30
40 - 2y = 30
subtract 40 from both sides to isolate y
-2y = -10
divide both sides by -2 to isolate y
y = 5
The first one is the second one. t(n)=20n+480
Question 4: is the first one t(n)=8n+15
Answer:
10. The sum of three consecutive odd numbers is 69. Find the numbers of P is the largest
number
Answer:
8
Step-by-step explanation:
A co-efficent is a number used to multiply a variable, and since 8x is the only variable, that means 8 is the only co-efficent.
