-ax-20=-14
add 20 to both sides
-ax=6
<span><span>4a+6b=10
4a=10-6b
a=(10-6b)/4
a=(5-3b)/2
</span>
<span>2a-4b=12
2((5-3b)/2)-4b=12
(5-3b)-4b=12
5-7b=12
-7b=7
b=-1
</span>
<span>2a-4b=12
2a-4(-1)=12
2a+4=12
2a=8
a=4
a=4, b=-1 </span>
12a=48</span>
Answer:
This is the graph of the question
Step-by-step explanation:
Answer:
time = distance / speed
time = 200/10
= 20

Answer:
Step-by-step explanation:
<em>Refer to attached</em>
- f(-2) = 1
- f(x) = -1 ⇒ x = -6
