13s=26
s=2
I think those are variables so that would be it.
x = 2 and y= 1
y = 3x-5
1= 3 x 2 - 5
1= 6-5
1=1
6x+3y=15
6 x 2 + 3 x 1 = 15
12+3=15
15=15
Answer:
The required function is F(x) = tanx - 2.
Step-by-step explanation:
We all know the graph of tanx ,
The graph of tanx passes through the origin and repeats in the interval of π.
Now , after looking into the graph we can clearly say that it is the shifted graph of tanx , Which is shifted in the -y direction .
Thus ,
It is clear that F(x) must be like F(x) = tanx - c , where c is a positive constant .
Also, At x = 0 , Value of the function is coming out to be -2 ,
Putting x = 0 in F(x) = tanx - c , we get , F(x) = -c .
Thus c = 2.
So, the required function is F(x) = tanx - 2.
Answer:
To make 3 kg of water, we need
0.5 kg water
1 kg cement
1.5kg sand
Step-by-step explanation:
Here, we want to calculate the mass of each component needed to make 3 kg of mortar
We work with the ratio
Total ratio is:
1 + 2 + 3 = 6
water
1/6 * 3kg = 0.5 kg
cement
2/6 * 3 kg = 1 kg
sand
3/6 * 3 = 1.5 kg
x-2, -2+x and x+(-2) are all the sum of x and -2.
2-x is the sum of -x and 2.
All of the following expressions are equivalent except
2-x.
