Write an equation of a line perpendicular to y=4x-3 that contains the point (0,7)

ExtremeBDS [4]

Let $k:y=m_1x+b_1$ and $l:y=m_2x+b_2$

$l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}$

We have

$y=4x-3\to m_1=4$

Therefore

$m_2=-\dfrac{1}{4}$

We have the equation of a line:

$y=-\dfrac{1}{4}x+b$

Put the coordinates of the point (0, 7) to the equation of a line:

$7=-\dfrac{1}{4}(0)+b\\\\\7=b\to b=7$

Answer: $\boxed{y=-\dfrac{1}{4}x+7}$

Hello, I'm trying to solve 6x + y = 4, x - 4y = 19. I have found the y but I cant seem to find the x. Plz help and we cant use d

Answer:

$x=\frac{7}{5}$

$y=-\frac{22}{5}$

Step-by-step explanation:

Given:

The given expressions are.

$6x+y=4$

$x-4y=19$

We need to find x and y values.

Solution:

Equation 1⇒ $6x+y=4$

Equation 2⇒ $x-4y=19$

First solve the equation 1 for y.

$6x+y=4$

$y = 4-6x$ --------(3)

Substitute $y = 4-6x$ in equation 2.

$x-4(4-6x)=19$

Simplify.

$x-(4\times 4 - 4\times 6x)=19$

$x-(16-24x)=19$

$x-16+24x=19$

Add 16 both side of the equation.

$25x-16+16=19+16$

$25x=35$

$x=\frac{35}{25}$

Divide Numerator and denominator by 5.

$x=\frac{7}{5}$

Substitute x value in equation 3 and simplify.

$y=4-6(\frac{7}{5})$

$y=4-\frac{6\times 7}{5}$

$y=4-\frac{42}{5}$

$y=\frac{5\times 4-42}{5}$

$y=\frac{20-42}{5}$

$y=-\frac{22}{5}$ .

Therefore, the value of $x=\frac{7}{5}$ and $y=-\frac{22}{5}$ .

Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughou

pashok25 [27]

A.) Rate of change = (1350 - 750) / (2010 - 2000) = 600/10 = $60
The initial value is the amount he charged in his first year of business which is $750.

B.) Required equation is given by y - 750 = 60x
y = 60x + 750 where x represent the number of years after 2000.
