Answer:
Step-by-step explanation:
the domain for (2x-1)/(x^2-7) is x not equal to +/- sqrt(7)
A. 8 pizza pies at 10 pc. per pie = 80 available pieces
B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.
c. 22 pieces are left over.
D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.
E. Solve the equation 58 = 5X by dividing both sides by 5.
WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.
Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.
Slope (or gradient) is used to determine if lines are parallel, as parallel lines share the same gradient.
The gradient is used to determine whether they intersect, as you'll have to plug x and y values in to both of the line's equations, which involves having the line's gradients.
The gradient is used to see if points are collinear, as you need to determine whether the gradient between two points is equal to the gradient of another 2 points, and if so, the points are collinear.
Finally, the gradient is used to find the equation of the line, as we require to plug in the gradient in to equations such as (y - y1 = m(x - x1)) in order to find the equation of the line.
Answer:
12 years
Step-by-step explanation:
8 feet = 96 inches
10 feet = 120 inches
96 + 6t = 120 + 4t
2t = 24
t = 12
