Answer:

Dasha has 52 roses

Step-by-step explanation:

Rewrite the first sentence in an equation: (D= Dasha) (A= Anna)

D=4A

Rewrite the second sentence in an equation:

A+39=D

1) Substitute A+39 as D in the first equation:

A+39=4A

2) Subtract A from both sides:

3A=39

3) Divide both sides by 3:

A=13

4) Now substitute 13 as A in the second equation:

13+39=D

5) Solve:

D=52

Solve x2 + 6x + 7 = 0. (2 points)
Alexandra [31]

Option C: $x=-3 \pm\sqrt{2}

Solution:

Given equation is x^{2}+6 x+7=0.

This is a quadratic equation.

Here a = 1, b = 6, c = 7

To solve the given equation by quadratic formula,

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}

Substitute the given values in the quadratic formula, we get

$x=\frac{-6 \pm \sqrt{6^{2}-4 (1) (7)}}{2 (1)}

$x=\frac{-6 \pm \sqrt{36-28}}{2 }

$x=\frac{-6 \pm \sqrt{8}}{2 }

$x=\frac{-6 \pm2 \sqrt{2}}{2 }

$x=\frac{2(-3 \pm\sqrt{2})}{2 }

2 in the numerator and denominator are cancelled.

$x=-3 \pm\sqrt{2}

Option C is the correct answer.

Determine the vertical asymptote. Simplify the function by factoring the denominator.
Brilliant_brown [7]
The function is equal to (x+2) / (x+2)(x-2), so when you simplify, it would be 1/(x-2). This means that there is a hole in the graph at x=-2, and a vertical asymptote at x=2.
