Answer:

x=-3

Step-by-step explanation:

1-7x-7=15

We move all terms to the left:

1-7x-7-(15)=0

We add all the numbers together, and all the variables

-7x-21=0

We move all terms containing x to the left, all other terms to the right

-7x=21

x=21/-7

x=-3

Naya [18.7K]

Answer:

Solution: f(x)\ge-5\\Interval:[-5,\infty)

Step-by-step explanation:

Equation: \frac{1}{4} x^2-5 = y

1). \frac{1}{4} x^2-5 = y →\frac{x^2}{4}-5=y

2). \frac{x^2}{4}-5=y ∴ a=\frac{1}{4}, b=0, c=-5

3). x_v=-\frac{b}{2a}

         =-\frac{0}{2(\frac{1}{4})}

         =0

4). now plug x_v into y_v

y_v=\frac{0^2}{4}-5

    =-5

5). Minimum (0,-5) ∴ f(x)\ge-5
