Are you saying 1\3 teeth?
Combining like terms............
3r^2 + 7r + 1 + 4r^2 - 8r - 2
7r^2 - r - 1
Answer:
24 years
Step-by-step explanation:
Let Christopher's age=c
Since Christopher is 20 years younger than Ishaan.
Ishaan's age=c+20
Fourteen years ago, Ishaan was three times as old as Christopher.
Their ages 14 years ago are:
For Christopher: c-14
For Ishaan: (c+20)-14
Therefore:
3(c-14)=c+6
3c-42=c+6
3c-c=6+42
2c=48
Divide both sides by 2
c=24
Christopher is 24 years old.
Answer:
y= 2× +4
Step-by-step explanation:
Slope intercept form y = mx +b
4x -2y = -8
-2y = -4x-8
y = 2x +4
slope = 2x
y intercept = 4
6x + 8y = 24
x intercept is the value when y =0 & y intercept is the value when x=0
for y=0 ==> 6x+0 =24 ==> x=4 for x=0==> 0+8y =24 ==> y=3
