The equation is 15000=850x+8000 because the total is 15000 and the you started with 8000 and you saved 850 each month. I hope that will help you
Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45

Answer:
2197 cm³
Step-by-step explanation:
surface area of cuboid = 2 * (5*9 + 33*9 + 33*5) = 1014
surface area of cube = 6 * x² .... x: side length of cube
6x² = 1014
x² = 169
x = 13
volume of cube = x³ = 13³ = 2197 cm³
Answer:
Prob [All marbles are red] = 0.0686 ;
Prob [None marble is red] = 0.1470
Step-by-step explanation:
Prob [All marbles are red] :-
= Prob(1st red marble & 2nd red marble & 3rd red marble)
= 8/18 x 7/17 x 6/16
= 0.0686
Prob [None marble is red] :-
= Prob (1st marble not red & 2nd marble not red & 3rd marble not red)
= 10/18 x 9/17 x 8/16
= 0.1470
