example: the line is y = ax + b
The line go through 2 points ( -4 ; 0 ) and ( 0 ; -2 )
So:
- -2 = 0a + b => b = -2
- 0 = -4a + (-2) => a = 2/-4 = -1/2
The line is y = -1/2x - 2 ( i'm not sure)
Answer: a
Ok done. Thank to me :>
Answer:
4.34
Step-by-step explanation:
2.48/40=0.062 per ounce
0.062 x 70 = 4.32 for 70 ounces
Answer:
N*B*x/100
Step-by-step explanation:
To determine an equation of the total number of dollars, it is necessary to review the variables that influence
The most important, N that would be the number of shares of A.
The other variable is B, since it would be the price of the shares that were purchased.
Lastly, we have x, since he originally had was A's shares, therefore his increase occurred in A's shares, that is, x.
Therefore, the equation would be:
N * B * x / 100
It is divided by 100 since x is a percentage.
As is the case for any polynomial, the domain of this one is (-infinity, +infinity).
To find the range, we need to determine the minimum value that f(x) can have. The coefficients here are a=2, b=6 and c = 2,
The x-coordinate of the vertex is x = -b/(2a), which here is x = -6/4 = -3/2.
Evaluate the function at x = 3/2 to find the y-coordinate of the vertex, which is also the smallest value the function can take on. That happens to be y = -5/2, so the range is [-5/2, infinity).
He is one meter and 87 centimeters tall.
