Answer:
-7
Step-by-step explanation:
given f(x)=4x+k
therfore, f(2)=4*2+k
we know that f(2) =1
so, 4*2+k=1
8+k=1
k=1-8
k=-7
Start the equation by putting the equations equal to each other 3x+14=7x-10
Next +10 on both sides
3x+14=7x-10
+10 +10
You are left with 3x+24=7x
because the 10's canceled each other out.
Next -3x on both sides
3x+24=7x
-3x +3x
You are left with 24= 10x
because like before the 3's canceled each other out
Now you will divide both sides by 10
24=10x

Step-by-step explanation:
Answer:
Step-by-step explanation:
total degrees of a line is 180
4x+20+60=180
4x=100
X=25
20.015
Because there are 3 numbers before a thousand so 3 numbers behind the decimal are the thousandths.
