Answer:

Aaron's family will use 3 gallons of milk in thirty days.

Step-by-step explanation:

1. Multiply the amount of milk (1/2) times the days (30)

1/2 x 30 = 15

2. Divide 15 by 5 (every 5 days)

15 / 5 = 3

The quadratic equation -6=x^2+4x-1 in Standard form . What is the value of c in his new equation

Vitek1552 [10]

Answer:

c = 5

Step-by-step explanation:

A quadratic equation in standard form is

ax² + bx + c = 0 : a ≠ 0

Given

- 6 = x² + 4x - 1 ( add 6 to both sides )

0 = x² + 4x + 5 ← in standard form

with c = 5

What values complete each statement?

aliya0001 [1]

For this case we have:

By properties of the radicals $\sqrt {a} = a ^{\frac {1} {2}}$

So:

$(\sqrt {7}) ^ 2 = (7 ^ {\frac {1} {2}}) ^ 2$ .

Now, for power properties we have:

$(b ^ {\frac {c} {d}}) ^ e = b ^ {\frac {c * e} {d}}$

Thus, $(7 ^ {\frac {1} {2}}) ^ 2 = 7 ^ {\frac {2} {2}} = 7$

So:

$7 ^ {\frac {1} {2}} = \sqrt {7}$ in its radical form

Answer:

$(\sqrt {7}) ^ 2 = (7 ^ {\frac {1} {2}}) ^ 2= 7 ^ {\frac {2} {2}} = 7$ in its simplest form.

$7 ^ {\frac {1} {2}} = \sqrt {7}$ in its radical form

Given that g(y) = y2 - 1, find g(a - 1).<br>Give your answer in its simplest form.

AlekseyPX

Answer:

a^2 - 2a.

Step-by-step explanation:

Replace the y in g(y) by a - 1 and simplify.

g(a-1) = (a - 1)^2 - 1

= a^2 - 2a + 1 - 1

= a^2 - 2a.
