The graph of a quadratic function y = ax² is a VERTICAL parabola open upward or downward depending whether a (the coefficient of x) is positive or negative
The graph y² = ax or y = √ax is a HORIZONTAL parabola open to the right or to the left depending whether a (the coefficient of x) is positive or negative
Answer:
12/-11 is the multiplicative inverse of -11/12..
Step-by-step explanation:
Answer:
8+10+8+10=36+ 2 x 3.14 x radium/2
Step-by-step explanation:
<h3><u>The value of the smaller number, y, is equal to 9.</u></h3><h3><u>The value of the larger number, x, is equal to 12.</u></h3>
x + y = 21
x = 2y - 6
We have a value for x, so we can plug it into the original equation to solve for y.
2y - 6 + y = 21
Combine like terms.
3y - 6 = 21
Add 6 tot both sides.
3y = 27
Divide both sides by 3.
y = 9
Now that we have a value for x, we can plug it into the 2nd equation to solve for x.
x = 2(9) - 6
x = 18 - 6
x = 12
