PLS HELPPPP equation of the line that is parallel to the line y − 3x = 4 and passes through the point (0, −3)

Volgvan

Answer:

y = 3x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y - 3x = 4 ( add 3x to both sides )

y = 3x + 4 ← in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c

The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = 3x - 3 ← equation in slope- intercept form

Plzzz help with all of the questions and plzZZZzZz show work I really need help I’m not understanding help with all the question

Answer:

slope of EF= $\frac{5}{3}$

∠QSR=45°,

∠PTQ=90°

if RT=24

then SQ=48

square is always a rectangle

∠SUT=21°

Step-by-step explanation:

two line are perpendicular to each other if product of their slope equal to -1

$m_{1}\times m_{2}$ =-1

slope of HE= $m_1$ =- $\frac{3}{5}$

slope of EF= $m_2$

slope of EF=-1 $\frac{-5}{3}$ = $\frac{5}{3}$

slope of EF= $\frac{5}{3}$ answer

∠QSR=45°,

∠PTQ=90°

if RT=24

then SQ=48

square is always a rectangle

given ∠SUT=3x+6

∠RUS=5x-4

∠SUT=∠RUS

3x+6=5x-4

x=5

∠SUT=3x+6=15+6=21°

∠SUT=21°

Which of the following describes the end behavior of y= -x^2 + bc + c as x approaches either positive or negative infinity?

NNADVOKAT [17]

y= -x^2 + bc + c represents a vertical parabola that opens down. As x approaches either + or - infinity, the function approaches - infinity. Imagine an upside down parabola; doing so will confirm this answer.

Select the correct answer. Rewrite the following expression.

kolezko [41]

The algebraic expression $x^{10/3}$ is equivalent to the algebraic expression $x^{3}\cdot \sqrt[3]{x}$ . Thus, the right choice is option D.

<h3>How to apply power and root properties to rewrite a given expression</h3>

In this question we must apply the following set of algebraic properties to simplify a given expression:

$x^{m/n} = \sqrt[n]{x^{m}} = \left(\sqrt[n]{x}\right)^{m}$ (1)

$x^{m+n} = x^{m}\cdot x^{n}$ (2)

$x^{m\cdot n} = \left(x^{m}\right)^{n} = \left(x^{n}\right)^{m}$ (3)

Where:

m, n - Exponents
x - Base

And also by apply the definition of power.

If we know that the given expression is $x^{10/3}$ , then the equivalent expression is:

$x^{10/3} = \sqrt[3]{x^{10}} = \sqrt[3]{x^{9}\cdot x} = \sqrt[3]{x^{9}}\cdot \sqrt[3]{x} = x^{3}\cdot \sqrt[3]{x}$

The algebraic expression $x^{10/3}$ is equivalent to the algebraic expression $x^{3}\cdot \sqrt[3]{x}$ . Thus, the right choice is option D.
