Perimeter = Sum of three sides.
Let the third side be = t
Perimeter = 8x + 3y
8x + 3y = (4x + y) + (2x - 3y) + t
8x + 3y = 4x + y + 2x - 3y + t
8x + 3y = 4x +2x + y - 3y + t
8x + 3y = 6x - 2y + t
8x - 6x + 3y + 2y = t
2x + 5y = t.
Therefore third side = 2x + 5y
Answer:
13km
Step-by-step explanation:
Given data
Time= 8 days
Speed= 2 1/6 kilometers per day = 13/6 kilometers per day
Distance= ??
We know that
Speed= distance/time
therefore, Distance= speed*time
substitute
Distance= 13/6*8
Distance= 104/8
Distance= 13 km
Hence the crew did 13km
Answer:
The red curve is the graph for given function.
Step-by-step explanation:
We are given the following function in the question:
We have to graph this function.
Properties of function:
- The given function is an exponential function of the form , where b is the base and x can be any real number.
- Here,
- It passes through the point (0,1).
- Since , the graph of function will decrease as we move from left to right.
- The domain for given function is all real numbers.
- The range for the given function is
The attached image shows the graph for the given function.
Answer:
the slope is undefined
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
m =(-9-3)/(5-5)
m = -12/0
the slope is undefined
Answer:
see below
Step-by-step explanation:
106
The tens place is the 0, so we look at the ones place
Since 6 is 5 or greater we round the tens place up
0 will round to 1, and the ones places goes to 0
106 rounds to 110
We need a number less than 180 that will round up to 180 from the tens place
We look at the tens place, it has to be less than 8 by 1
17 x
The number must be 5 or greater to round the 7 up to 8
175, 176, 177, 178, 179 will work
We need a number greater than 180 that will round down to 180 from the tens place
We look at the tens place, it has to be equal to 8
18 x
The number must be 4 or less to leave the 8 alone
180, 181, 182, 183, 184
