Hi there!
We can create an equation for the line PR using the given coordinates. Use the following formula for the slope:
Plug in the coordinates for P and R:
Find the equation by using point-slope form:
y - y1 = m(x - x1)
Plug in a coordinate and the slope:
y - (-5) = -4/3(x - ( - 1))
Simplify:
y + 5 = -4/3(x + 1)
To find the y-coordinate if x = 2, plug in the x value:
y + 5 = -4/3(2 + 1)
y + 5 = -4/3(3)
y + 5 = -4
y = -9
Thus, the coordinate is (2, -9)
Answer:
the answer is c
Step-by-step explanation:
its the right answer lol
Angle 1 is 107 degree, and the other one is 73 degrees (180-107=73)
Well we have the equation d = r * t
(d stands for distance, r for rate, and t for time)
So, plug in our values:
d = 55 *4
And, d = 220
I can't see the answer choices, but I hope this will help you!! Let me know if you have ANY questions.
Answer:
Step-by-step explanation:
For this case we need to find the following integral:
And for this case we can use the substitution 
from here we see that 
, and if we solve for x we got 
, so then we can rewrite the integral like this:
And if we distribute the exponents we have this:
Now we can do the integrals one by one:
And reordering the terms we have"
And rewriting in terms of x we got:
And that would be our final answer.
