First, we have two points and we need to use these points to find the slope. To do this, let's label one point x1 and y1, the other point x2 and y2 then,
Slope = (y2 - y1) / (x2 - x1)
(2, 3) - 2 is x1 and 3 is y1
(-1, -12) -1 is x2 and -12 is y2
Slope = (-12 - 3) / ( -1 - 2) = -15 / -3 = 5
Now the equation of our line is: y = 5x + b
Let's plug one of our points into this equation to solve for b.
3 = 5(2) + b
3 = 10 + b
Subtract 10 from both sides.
-7 = b
The equation of our line is: y = 5x - 7
Step-by-step explanation:
its 1/4 of the circle
circle circumference:
we need 1/4 of it, so its
First distribute the 2/3.
(2/3)n + (2/3)*6 = 10
(2/3)n + 4 = 10
Subtract 4 from both sides
(2/3)n = 6
Multiply both sides by (3/2) to clear the fraction
n = 9
Answer:
The fraction of the book Omarion read over the weekend=3/5
Step-by-step explanation:
Step 1
Determine the initial number of pages in a book that's remaining as follows;
Initial number of pages remaining=9/10 of the book
Step 2
Determine fraction of the book read over the weekend as follows;
fraction read over the weekend=fraction of the remaining read×initial number of remaining pages read
where;
fraction of the remaining read=2/3
initial number of remaining pages read=9/10
replacing;
fraction read over the weekend=(2/3)×(9/10)=3/5
The fraction of the book Omarion read over the weekend=3/5
