Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have
Solve for n
That means -----> isolate the variable n
Multiply by n both sides
Divide by 3.5*10^4 both sides
therefore
a=2, b=5
I don't get this I need help
1 answer:
We notice from the choices, that the problem is solved using the Pythagorean theorem somehow. How?
If ABC was a right triangle, the hypotenuse would be BC (the largest side), so the right angle would be A.
In that case we would have 54 squared (which equals 2916) equal to the sum of the squares of 22 and 51 (which equals 3085).
If the triangle was a right triangle,
would be exactly equal to 
, but it is larger. This means that a right angle is not large enough to 'enclose' . Thus angle A must be opened more that 90°.
Thus the answer is D:
an obtuse triangle because

The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed
Step-by-step explanation:
Given
Distance = d = 45 miles
Time = t = 3/4 hour
The unit rate is defined as the distance per unit time. In this case, the unit rate can also be called speed.
So,
Using this unit rate we can see if the car can travel 65 miles in 1.25 hours or not
Given
Distance = d1 = 65 miles
Speed = s = 60 miles per hour
Putting the values in the formula for speed
As we can see that 1.08 is less than 1.25 so the driver will reach the meeting before time if he drives on a constant speed of 60 miles per hour
Hence,
The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed

Answer:
The graph is attached Below and the plotting is given below.
Step-by-step explanation:
Given:
-9x + 6y = 18
Solution:
To draw a line on a graph the required minimum two points but here we will have three points as point A, point B, and point C.
For point A
Put x = -4 in the given equation we get
-9×-4 + 6y = 18
6y = 18-36
∴
∴ Point A ≡ ( -4, -3 ).
For point B
Put x = -2 in the given equation we get
-9×-2 + 6y = 18
6y = 18 - 18
6y = 0
∴
∴ Point B ≡ ( -2, 0 ).
For point C
Put x = 0 in the given equation we get
-9×0 + 6y = 18
6y = 18
∴
∴ Point C ≡ ( 0, 3 ).
Now we have Point A ,B and C join it and you will have Line.
