Step-by-step explanation:

6x² +66x +180= =6(x²+11x+30

but that's if its the parabola has indeed two real solutions

Answer:

66 x 1/11 = 6

66 x 0.09 = 6

So x = either 1/11 or 0.09

Hi!

When you add a negative number, you really just subtract it. So let's solve this.

Convert the mixed numbers into improper fractions.

$\frac{434}{9} - \frac{351}{9}$

Solve

434 - 351 = 83

$\frac{83}{9}$

The sign of this fraction is positive

Hope this helps! :)

Given a quadratic function in vertex form:

Alja [10]

Answer:

See below

Step-by-step explanation:

Part A

A vertical stretch takes place when $a\cdot f(x)$ given that $|a| > 1$

Part B

A vertical compression takes place when $a\cdot f(x)$ given that $0 < |a| < 1$

Part C

A vertical stretch is different than a horizontal compression:

In a vertical stretch, the input stays the same, but the output is multiplied by the scale factor
In a horizontal compression, the output stays the same, but the input is multiplied by the scale factor

Part D

A reflection across the x-axis means that the output, our y-variable, is the opposite sign. This means that all values of $a$ must be negative such that $a\cdot f(x)$ as mentioned in parts A and B. Also, in part C, since our scale factor is negative, the output is the only one being multiplied by the scale factor.
