Yes,this is a doozy.
<u>-3 (y - 5) = 15</u>
Eliminate the parentheses on the left side:
-3(y) -3(-5) = 15
-3y + 15 = 15
Subtract 15 from each side:
-3y = 0
Divide each side by -3 :
<em> y = 0</em>
Answer:
20x-21y+14
Step-by-step explanation:
1/5(100x-105y+70)
20x-21y+14
Step-by-step explanation:
it is a linear function, if the change in y is constant in relation to the changes of x.
in other words, if the slope y change/x change is the same for every point.
when we look at the table, we see x changes constantly by +2.
and y changes constantly by -6.
so, the change rate/slope is constantly -6/2 = -3.
and therefore it is a linear function.
the equation looks like (the slope is always the factor of x)
y = -3x + b
b we get by using one of the x,y pairs like 1,4
4 = -3×1 + b = -3 + b
b = 7
so, the full equation is
y = -3x + 7
- 12 + x ≥ 3 (x - 6)
- or, 12 + x ≥ 3x - 18
- or, 12 + 18 ≥ 3x - x
- or, 30 ≥ 2x
- or, 30/2 ≥ x
- or, 15 ≥ x
- or, x ≤ 15

Hope you could get an idea from here.
