Answer:
-16
Step-by-step explanation:
Substitute the given values and do the algebra.
(f(x+h) -f(x))/h = ((28 -16(x+h)) -(28 -16x))/h
= (28 -16x -16h -28 +16x)/h = -16h/h = -16
The answer will be Negative
At x=6
0=2x-12
12=2x
12/2=6
X=6 at y=0
Suppose robbie buys x scones then according to the question.....cameron will have x+y
..lou's will have (x+y)+y=x+2y ...
Tom=x+3y....
Charlie=x+4y.....
now as we know that the combines scones of robbie and Cameron is 3/7 times of total of louis.....
x+(x+y)=3/7 (x+3y+x+2y+x+4y)....solve this ...and this will be your 1st equation...and second equation will be x+x+2y+x+3y+x+4y=60.......And solve both equation simultaneously and then you will have the answers of x and y the put the values of x and y in each of the equation that i have written above for each person
If the sum of the square of a number plus the triple of the same number equals eighteen, the required numbers are 3 and -6
Let the unknown number be x
The square of the number is expressed as x²
Triple of the unknown number will also be expressed as 3x
Taking the sum of both numbers and equating it to 18 will give;
Factorize the resulting equation:
Hence the required numbers are 3 and -6
