Answer:

The given parabola opens to the left.

Step-by-step explanation:

We are given,

The equation of the parabola is x=ay^2

If in the parabola,

<em>1. If 'a' is positive, then the parabola opens upwards or right.</em>

<em>2.</em><em> If 'a' is negative, then the parabola opens downwards or left.</em>

Moreover,

<em>3. If x is squared, then the parabola opens upwards or downwards.</em>

<em>4. </em><em>If y is squared, then the parabola opens left or right.</em>

Now, as we are given the parabola having y^2 and 'a' is negative.

Thus, from the points 4 and 2, we get,

The given parabola opens to the left.

In Mr. Cannon's class, 44% scored an 80 or above on the semester exam. Which of the following is NOT equivalent to 44% Question
tigry1 [53]

Answer:

11/20

Step-by-step explanation:

22/50 is equivalent because if you multiply 50 by 2 to get 100, then multiply 22 by 2, you get 44 out of 100 (44). For 11/20 if you multiply 20 by 5 to get 100, then multiply 11 by 5, you get 55 out of 100 (55). Do the same thing for all the other ones. I hope this helps! Please mark me brainliest thanks!

For the table below, determine the function rule, and find each of the missing y-values.
anygoal [31]
The answer is 8 and 13

<span>
y = ax + b
y = 4, x = 1        </span>⇒  4 = a + b
y = 6, x = 3       ⇒  6 = 3a + b

Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3

So, the function rule is: y = x + 3

Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13
