hi dont report me we are friends can i get brainliest plzz?
Step-by-step explanation:
<span>Let us start with the plane flying east at a slower speed. Let us assume that its speed is x kilometers per hour. After 4 hours, it will have traveled 4*x = 4x kilometers.
Now let us calculate the speed of the plane flying west. It is faster by 75 kilometers per hour than the other plane. So its speed per hour is x+75 kilometers per hour. After 4 hours, it will have traveled 4( x+75) = 4x+300 kilometers. The total distance traveled by both the planes is 5460 kilometers. In other words, 4x+4x+300 =5460 kilometers.
Now simplify the equation:
8x + 300 = 5460
8x = 5460 - 300
8x = 5160
x = 5160/8 645.
x is the speed of the plane flying east. It is 645 kilometers.
x + 75 is the speed of the plane flying west. It is 645 + 75 =
720 kilometers.</span>
First, you subtract 5h from both sides.
-9 = -16 + h
Then, you add 16 to both sides.
7=h
So, h = 7.
The solution that makes both equations true is 'a', or (2,0), because if you substitute the 2 with the x and the 0 with the y, and solve both equations, you get the same answer. Also, you could try a graphing software, like desmos.
0=-2(2)+4
-4+4
0=0
0=(2)-2
0=0
When a customer has a 6 pound Chihuahua, the cost that will be charged is $5.00.
<h3>How to calculate the cost?</h3>
a. If a customer has a 6 pound Chihuahua, how much would you charge?
It should be noted that from the information given, for dogs that weigh 0 to 15 pounds, the amount charged is $5.00.
b. If a customer has a 65 pound Labrador, how much would you charge?
It should be noted that for dogs over 45 pounds, the amount that's charged is $9.00
There, the amount charged will be $9.00.
