Answer:
23.25 MPH
Step-by-step explanation:
7 3/4 x 3 = 23.25
1/3 x 3 = 3/3 = 1
So for 1 hour she will ride 23.25 MPH :D
Answer:
x = - 1, y = 3 or (-1 , 3)
Step-by-step explanation:
x – 3y + 10 = 0 x = 3y - 10 ... plug in
x² + y² = 10
(3y-10)² + y² = 10
10y² - 60y +90 = 0
y² - 6y + 9 = 0
(y - 3)² = 0
y = 3
x = - 1
A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. It's possible to simplify this to y = mx + b, where m = ( −A / B) and b is the value of y when x = 0. A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c. Apart from the adding complexity of solving a quadratic equation compared to a linear one, the two equations produce different types of graphs.

0.04 of a chance
because 1 chapter has 20 pages and the book has 500
so the chance of you flipping to chapter 12 out of 500 pages is 4% of a chance
