What is an equation of the line that passes through the point (8,-7)(8,−7) and is parallel to the line 5x+4y=165x+4y=16?

gizmo_the_mogwai [7]

Answer:

The equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 is $\mathbf{y=-\frac{5}{4}x+3}$

Step-by-step explanation:

We need to write an equation of the line that passes through the point (8,-7) and is parallel to the line 5x+4y=16.

The equation will be of form $y=mx+b$ where m is slope and b is y-intercept.

Finding slope of the line:

Since both the lines are parallel, and we know that parallel lines have same slope.

The slope of given line $5x+4y=16$ can be found by writing in slope-intercept form $y=mx+b$

$5x+4y=16\\4y=-5x+16\\y=-\frac{5}{4}x+16$

Comparing with $y=mx+b$ the slope m is: $m=-\frac{5}{4}$

So, the slope of required line is: $m=-\frac{5}{4}$

Now, finding y-intercept b

y-intercept can be found using slope $m=-\frac{5}{4}$ and point (8,-7)

$y=mx+b\\-7=-\frac{5}{4}(8)+b\\-7=-5(2)+b\\-7=-10+b\\b=-7+10\\b=3$

So, we get y-intercept: b=3

Now, the equation of required line having slope $m=-\frac{5}{4}$ and y-intercept b=3 is:

$y=mx+b\\y=-\frac{5}{4}x+3$

So, the equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 $\mathbf{y=-\frac{5}{4}x+3}$

Which equation demonstrates the distributive property?

Art [367]

The correct option of your question is D

Step-by-step explanation:

To solve the sum we need to understand the distributive property

a×(b+c) = a×b + a×c

Here,

Option D is given as

RHS = 5(3+8) [ a=5, b=3 and c=8]

=15 + 40

= LHS

It satisfies the distributive property.

You can cross check the property with the other options.

D is the correct option.

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give

Darina [25.2K]

Answer:

$x-ey=e+e^2$

Step-by-step-explanation:

We are given that

$y=lnx$

Point (e,e)

We have to find the equation of tangent line to the given graph.

Differentiate w.r.t x

$\frac{dy}{dx}=\frac{1}{x}$

By using formula

$\frac{d(lnx)}{dx}=\frac{1}{x}$

Substitute x=e

$m=\frac{dy}{dx}=\frac{1}{e}$

Slope-point form:

$y-y_1=m(x-x_1)$

$x_1=e,y_1=e$

By using this formula

The equation of tangent to the given graph

$y-e=\frac{1}{e}(x-e)$

$ey-e^2=x-e$

$x-ey=e+e^2$
