$-3\ \textgreater \ -7+4t$ $:|\text{Regroup terms}$

$-3\ \textgreater \ 4t-7$ : $|\text{Add 7 to both sides}$

$-3+7\ \textgreater \ 4t$

$4\ \textgreater \ 4t$

$1\ \textgreater \ t$ $:|\text{ Divide both sides by 4}$

$t\ \textless \ 1$ $:|\text{Switch sides}$

What are the steps to this problem (and the answer?)

Svetradugi [14.3K]

Answer:

$(25 {x}^{2} + 20xy + 16 {x}^{2} )(5x - 4y) = \\ 125 {x}^{3} + 100 {x}^{2} y + 80x {y}^{2} - 100 {x}^{2} y \\ - 80x {y}^{2} - 64 {y}^{3} = \\ 125 {x}^{3} - 64 {y}^{3} \\ please \: give \: brainliest$

Which is an equation of the line through (-1, -4) and parallel to 3x+y=5

kherson [118]

Answer:

Step-by-step explanation:

3x + y = 5 {subtract 3x from both sides}

y = -3x + 5 ← slope-intercept form

y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂

{Two lines are parallel if their slopes are equal}

y = -3x + 5 ⇒ m₁ = -3 ⇒ m₂ = -3

(-1, -4) ⇒ x₁ = -1, y₁ = -4

The point-slope form:

y - (-4) = -3(x - (-1))

y + 4 = -3(x + 1)

y + 4 = -3x - 3 {subtact 4 from both sides}

<h3><u>y = -3x - 7 </u><u> ← slope-intercept form</u></h3>

In a circuit, two resistors of 100 Ω and 80 Ω are connected in parallel. The parallel group is then connected in series with a 1

nordsb [41]

Answer:

Total Resistance = $\frac{1300}{9}$ Ω (or 144.44 Ω)

Step-by-step explanation:

If two resistors, with resistance x and y, are connected in parallel, their total resistance is given by the formula:

$\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}$

If 2 resistors with resistance x and y and connected in series, their total resistance would be:

Total = x + y

<em>Now, the first part, 100 and 80 are in parallel, so according to formula it would be:</em>

<em> $\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}\\\frac{1}{Total}=\frac{1}{100}+\frac{1}{80}\\\frac{1}{Total}=\frac{9}{400}\\Total = \frac{400}{9}$ </em>
