Answer: 7/26
Step-by-step explanation:
7 red and 7 blue = 14 total
7/14 or 1/2 chance of getting red first
7/13 chance of getting red the second time
7/13*1/2 = 7/26
7/26 chance
sorry if it’s wrong but I hope it helps
Answer:

Step-by-step explanation:
The function is
, whose first derivative is:

Let equalize the derivative to zero:





The solutions are given by the following inverse trigonometric function:

The answer is 35
Since they are supplementary they both equal 180 degrees.
(3x+10)+(2x-5)=180
Add them up
5x-5=180
Subtract 5 from both sides
5x=180-5
5x=175
Divide 5 from both sides
x=35.
Answer:
The equation is;
4y = 7x + 2
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
m = (y2-y1)/(x2-x1)
(x1,y1) = (2,3)
(x2,y2) = (-2,-4)
m = (-4-3)/(-2-2) = -7/-4 = 7/4
So we have the equation as;
y = 7x/4 + b
To
get the value of b, we will substitute any of the points (let us use 2,3)
We simply substitute 2 for x and 3 for y
We have this as:
3= 7(2)/4 + b
3 = 7/2 + b
b = 3-7/2 = -1/2
So we have the equation as;
y = 7x/4 + 1/2
multiply through by 4
4y = 7x + 2
what is the best and easiest method to use to find sides A and B?
B
