Enrique did have enough money to buy the DVD, because 2/4 equals $4, 1 1/4 equals $10, and 3/4 equals $6, if you add those together then it'll equal exactly $20.
Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.




(2) Subtract adjacent differences in (1) above



Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
Answer:
90
Step-by-step explanation:
Answer:

Step-by-step explanation:
So we know that:

And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:

Now, solve for x. Add 30 to both sides. The left side cancels:

Now, subtract 2x from both sides. The right cancels:

Thus, the value of x is 21.
Answer:
It looks like the slope is -2
