Answer: 16
Step-by-step explanation:
let a = your present age
a = 2(a+4) - 2(a-4)
a = 2a + 8 - 2a + 8
a = 2a - 2a + 8 + 8
a = 16 yrs is your age
4y ≥ 3x + 2
Plugging in the values in the options, then the required values are when x = 6 and y = 5, then
4(5) ≥ 3(6) + 2
20 ≥ 18 + 2
20 ≥ 20
The best way to do this is to set up a proportion
2 5
--- = ----
5 x
then cross multiply and divide
5 times 5=25/2=12.5
he would move 12.5 feet in 5 hours
I hope I've helped!
-7x + 6y =5
x intercept. y=0
-7(x) + 6(0)=5
x=-5/7
y intercept, x=0
-7(0)+6(y) =5
y=5/6
