We would first determine how to solve this, and then from there, we would then see whether the following answer would be the correct answers.
Now, we can determine whether the say "yes" or "no" to the following answers.
<span>
a 2(x-5)(x+5) = YESb -2(x+5)(x+5) = NO
c -2(5-x)(x+5) = NO</span>
The value (y2) of r = 1/2.
This question relates to equation of a straight line but we are looking for the slope in this case.
<h3>Slope</h3>
This is the ratio to which we measure the change along the y-axis to the change along the x-axis. The formula is given as
Data given;
- x1 = 3
- x2 = -3
- y1 = 5
- y2 = r
- m = 34 or 3/4
Substitute the values into the equation and solve for the unknown
NB; we are assuming that the slope here is 34 and not 3/4.
cross multiply both sides and make r the subject of formula
the value of r = -199.
This is not mathematically obtainable and we would use 3/4 as the value of slope
The most logical value of r = 1/2

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
Here the two samples should be comparable .
The total number of cows in the farm = 200
the total number of cows giving milk = 150
the total number of cows in corral = 20
Suppose total number of cows giving milk in corral = x
The ratio of the total number of cows present to the total number of cows giving milk should be same in farm and corral
so : 200 = 20
------- -------
150 x
now we do cross multiplication :
200 x = 150* 20
200x = 3000
x= 3000/200
x= 15
SO we expect 15 cows in corral should be giving milk .
Answer : 15
