Notice the picture below
so, the two triangles are similar by AA
thus

solve for "x"
Answer:
-3x-3
Step-by-step explanation:
We want our equation to look like this
y=mx+b
we know that m= -3 so we just need to find b
We can start by plugging in the ordered coordinates into our equation
3=(-3)(-2)+b
Solve for b
3=6+b
b= -3
Which means our final equation is
y= -3x-3
The average speed is 104 kilometer per hour
<em><u>Solution:</u></em>
Given that,
A car drives 494 km in 4 hours 45 minutes
To find: Average speed in kilometers per hour
<em><u>The average speed is given by formula:</u></em>

From given,
Distance = 494 km
Time = 4 hours 45 minutes
We know that,
1 hour = 60 minutes
Therefore,

Thus,
time = 4 hours 45 minutes = 4 hour + 0.75 hour = 4.75 hour
<em><u>Thus average speed is:</u></em>

Thus average speed is 104 kilometer per hour
Hello!
Rate of income tax = Tax paid / Monthly income
⇒ Rate = 8,000 / 40,000
⇒ Rate = 0.2
⇒ Rate = 20%
