Answer:
Step-by-step explanation:
Let m be the number of months.
It has been given that Svetlana's hair is 4 centimeters long. So 4 will be constant for our equation.
Her hair grows 1.5 centimeters per month. So the length of Svetlana's hair after m months will be 1.5m.
Svetlana wants her hair to grow so that it is at least 7 centimeters long. So the length of svetlana's hair after n months plus 4 should be greater than or equal to 7.
We can represent this information in an equation as:
Therefore, the inequality will represent the number of months, m, it will take Svetlana's hair to grow at least 7 cm long.

Answer:
1.5 seconds
Step-by-step explanation:
plug 0 in for y
0=-16t^2+36
then slove for t
-36=-16t^2
-36 / -16 = 9/4
9/4=t^2
square root of 9/4 is 3/2 or 1.5
t=1.5
<span>Train x miles --------- 70 mph
Bus 293-x miles---------40 mph
time train + time bus = 5
t=d/r
x/70 + (293-x)/40 = 5
Multiply by LCD 2800
</span><span>40x+70(293-x)= 5 * 2800
-30x+20510=14000
-30x=-6510
x=-6510/-30
x=217----------- train distance
balance bus distance </span>
3x - 6y = -15
5x - 2x = 3x
-9y + 3y = -6y
-26 + 11 = -15
