Answer:

28 $\sqrt{6}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

$\sqrt{96}$

= $\sqrt{16(6)}$

= $\sqrt{16}$ × $\sqrt{6}$

= 4 $\sqrt{6}$

Then

7 $\sqrt{96}$

= 7 × 4 $\sqrt{6}$

= 28 $\sqrt{6}$

Step-by-step explanation:

$\begin{array}{cccc}\bf{Week}& \textbf{Earned/Spent} & \textbf{Change} & \textbf{Net Change}\\1 & \text{Earned \$80} & + 80 & + 80\\2 & \text{Spent \$85} & \mathbf{- 85} &\mathbf{-5}\\\end{array}$

The net chance in Jacob's savings was +80 in the first week, -85 in the second week, and -5 overall.

When reflected across the y axis, the x coordinate becomes the opposite but the y coordinate stays the same, so N is (2, -5)

Which equation shows 4n=2(t-3) solves for t?

noname [10]

Answer:

t = 2n + 3

Step-by-step explanation:

Given

4n = 2(t - 3) ← divide both sides by 2

2n = t - 3 ( add 3 to both sides )

2n + 3 = t

Which of the following is the correct graph of the solution to the inequality −8 greater than or equal to −5x + 2 > −38? (1 p

Svetlanka [38]

The inequality should read:

$-8 \geq -5x + 2 > -38$

Subtract 2 from all the terms:

$-10 \geq -5x > -40$

Divide all the terms by -5 to get x by itself (note that you flip the inequality signs as you divide by a negative):

$\boxed{2 \leq x < 8}$

The inequality is 2 ≤ x < 8.

A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.

The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.
