D) 6x≥360; x≥60
Step-by-step explanation:
The goal is to save at least $350 over the next 6 weeks.
Let the amount to save per week be x
x *6 should be equal or more than the goal.This is
6x ≥ 360
However, dividing the goal amount by number of weeks to get the amount to save per week gives;
360/6 =60
so x≥ 60
The inequality is thus : 6x ≥360;x≥60

Answer:
one solution, i.e x = 1 and y = -2
Step-by-step explanation:
Given two equations :
x+3y = -5 -------(1)
4x - y =6 ---------(2)
Using elimination method,
Multiply equation (2) by 3 and add it to equation (1)
We get,
x + 3y + {(4x - y)×3} = -5 +(6×3)
x + 12x + 3y - 3y = -5 + 18
13x = 13
x = 13/13 = 1
And corresponding y will be:
x + 3y = -5 , Plug x =1 to get y
1 + 3y = -5
3y = -5 - 1
y = -6/3 = -2
Hence we got only one solution, i.e x =1 and y = -2
Since x=3 that means all of the x's would be 3's
