Semmy [17]3 years ago
5 0

Answer:

y = - 2, y = - 1

Step-by-step explanation:

y² + 3y + 2 = 0

Consider the factors of the constant term (+ 2) which sum to give the coefficient of the y- term (+ 3)

The factors are + 2 and + 1 , since

2 × 1 = 2 and 2 + 1 = 3 , then

(y + 2)(y + 1) = 0

Equate each factor to zero and solve for y

y + 2 = 0 ⇒ y = - 2

y + 1 = 0 ⇒ y = - 1

The line to the right goes through the point (6, y). If the angle the graph makes with the x-axis is 22°, what is
s344n2d4d5 [400]

Answer:

The y-coordinate of the point is approximately 2.42.

Step-by-step explanation:

From the figure attached below the statement we derive the following equation to calculate the y-coordinate (y), dimensionless, of the point in terms of the x-coordinate (x), dimensionless, and angle of the line (\theta), measured in sexagesimal degrees:

y = x\cdot \tan \theta (1)

If we know that x = 6 and \theta = 22^{\circ}, then the y-coordinate of the point is:

y = 6\cdot \tan 22^{\circ}

y\approx 2.42

The y-coordinate of the point is approximately 2.42.

Natalie's group brought in pizza but is buying drinks at the concession stand medium sodas are a dollar and $.25 how many medium
Phantasy [73]

Keywords:

<em>Medium sodas, buy, dollars, divide </em>

For this case we must find the amount of medium sodas that Natalie's group can buy, taking into account that they have 20 dollars and that each medium soda costs 1.25 dollars. To solve, we must divide:

Let "x" be the number of medium sodas you can buy, then:

x = \frac {20} {1.25}\\x = 16

So, Natalie's group can buy 16 medium sodas with 20 dollars

Answer:

16 medium sodas
