Answer:
x=8
y=-3
Step-by-step explanation:
let
x+y=5........ equation 1
x-4y=20....... equation 2
x=20+4y
substituting the value of x in eq 1
x+y=5
20+4y+y=5
5y=5-20
y=-15/5
y=-3
again putting the value of y in eq 2
x=20+4y
x=20+4(-3)
x=20-12
x=8
Answer:
the 4 pack, if you get 2 it's 4.14 instead of 9 for 4.68
Answer:
y ≥ -x +2
Step-by-step explanation:
The solid line has a slope of -1 and a y-intercept of 2, so its equation in slope-intercept form is ...
y = -x +2
The shaded area is above this line, and the line is part of the solution set, so we want an inequality that has "y" and the comparison symbol in this order: "y ≥" or "≤ y".
We already have an equation with "y" on the left, above, so we just need to introduce the comparison symbol:
y ≥ -x +2
Another way to write this is ...
x + y ≥ 2
They are both wrong because 84*5 equals 420 times 657 equals 275940 and84 plus 573 plus 9 is 666
