Answer:
f(x)=-10
Step-by-step explanation:
when you have f of x...any x gets the filled in by the number that is next to f
so f(x)=4x+2
f(x)=4*-3+2
f(x)=-10
The answer to the first one is 15.6 and the second one is 1.76
Step-by-step explanation:
30=-5(6n+6)
30=-5×6n-5×6
30=-30n-30
30+30=-30n
60=-30n
60/-30=-30n/30
-2=n
First, let's add 30 to both sides:
4x - 30 +30 ≥ -3x + 12+30
4x ≥ -3x + 42
Now, let's add 3x to both sides
4x +3x ≥ -3x+3x + 42
7x ≥ 42
Let's divide both by 7:
x ≥ 6
Blue is 42 and green is 30
