The answer here is A which is the first graph.
Remember that if a is negative in the equation y = ax^2 + bx + c, the parabola always opens downward. For vertex, its coordinates is always located on the first quadrant in which all values are positive.

Make b the subject.
sp2606 [1]
First, square both sides. This will cancel out the radical.
a^2 = b \add 6
(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6

<h3>Answer:</h3>

The Slope is 2

<h2>Explanation:</h2>

Notice that both the points, (60,0) and (70,20), are on the line. So we can use those points to calculate the slope. Recall that that slope of the line m can be calculated by \frac{y_2 -y_1}{x_2 -x_1}\\ if we have the points, (x_1,y_1) and (x_2,y_2).

<h3>Calculating for the slope of the line:</h3>

Given:

(60,0)

(70,20)

m = \frac{20 -0}{70 -60} \\ m = \frac{20}{10} \\ m = 2

The lines intersect at point C. What is the value of x?
Agata [3.3K]

<u>Answer:</u>

The correct answer option is 21.

<u>Step-by-step explanation:</u>

We know that the given lines PW and AD intersect at the point C.

Therefore, the two given angles are equal to each other and we can write them in the form of an equation as:

(4x - 4)° = (3x + 17)°

Solving for x to get:

4x - 4 = 3x + 17

4x - 3x = 4 + 17

x = 21

Therefore, the value of x is equal to 21.

Juan wants to make a new game board that is a grid containing 25 equally sized squares. How many squares should be shaded to cre
pickupchik [31]

Let the number of shaded square be x. And it is given that total number of squares are 25.

probability = \frac{shaded \ squares}{total \ squares}

Substituting the values

0.2 = \frac{x}{25}

Performing cross multiplication

0.2*25=x \\ x = 5

So 5 squares should be shaded to create a region with a geometric probability of 0.2 .
