is it factorisatiom or solving equation?
Step-by-step explanation:
2m² + 2m - 12 divide the equation by 2
then: m² + m - 6
factorise: (m + 3)(m - 2)
solve m + 3 =0 or m - 2 =0
m= -3 or m = 2
Just multiply 5:13 by any number
10:26
15:39
20:52
25:65
etc...
Answer:
x=5
Step-by-step explanation:
16x+5=85
16x=80
x=5
So in this equation we're given that Ravi puts $350 into his account, this means that when W=0, S=350. Or that the y-intcpt(b) is 350.
when we find an equation we use slope intcpt formula:
y = mx + b
M in this case is the slope or the amount S
changes for every value of W. So if Ravi adds $70 every day that means the amount of money in his account increases by $70 everyday, so we can say m= 70
So putting together the equation with b= 350 and m = 70 we get :

Calculating for 17 weeks or W = 17

Ans: $1540
