The value of 28 tens is 280 because a ten is literally 10 you only multiply 28*10= 280 So the value of 28 tens is 280.
Thank You!
Answer:
y = -2x - 4
Step-by-step explanation:
Formula is y = mx + b where m is the slope and b is the y-intercept
(1, -6) (-3, 2)

The slope is -2
y = -2x + b
So let's find b, insert 2 for y and -3 for x to find b
2 = -2(-3) + b
2 = 6 + b
Subtract 6 from both sides to get b alone
-4 = b
We found what b equals (the y-intercept), which is -4
So, the equation is y = -2x - 4
Hope this helps and pls do mark me brainliest:)
Answer:
x=5
Step-by-step explanation:
f(x) = 7
We want to find the x value so that y = 7
Looking at the graph, the x value when y = 7 is x=5
f(5) =7
Given:
The minimum and maximum distance that the dog may be from the house can be found by using the equation:

To find:
The minimum and maximum distance that the dog may be from the house.
Solution:
We have,

It can be written as:

Adding 500 on both sides, we get

Now,
and 
and 
The minimum distance is 492 meters and the maximum distance is 508 meters.
Therefore, the correct option is C.
