Answer:
x=135°
Step-by-step explanation:
45°- 180°=135x
400 = 45x + 30x
400 = 75x
5.333 = x
Lets test
45mph for 5.333 hours = 240 miles
30mph for 5.333 hours = 160 miles
240 + 160 = 400 miles apart.
because it colorado and you can never tell what the weather is
<span>f(x)=|2x+1|+5
f(-3) = </span><span>|2*-3 + 1|+5
= </span><span>|-6 + 1|+5
</span>= <span>|-5|+5 = 5 + 5 = 10
</span><span>
f(-3) = 10 </span><span>
</span>
