Answer:
The third (y=2x–5)
Step-by-step explanation:
y=2x–5
if we substitute then:
3=2(4)–5
3=8–5
5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9
=
=
3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92
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
