Answer:

18.57

Step-by-step explanation:

First you have to simplify the equation using cross-multiplication

You should get 7v=130

Then divide both sides by 7

You should get v=130/7

simplify that and get 18 4/7

Turn that into decimal form and you get 18.57

Answer:

16. $y=7x$

17. $y=0.5x$

18. $y=3x$

19. $y=2x$

Step-by-step explanation:

Equation is $y=kx$ where k is a constant of proportionality.

16.

$\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7$

So, equation is $y=7x$

17.

$\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5$

Equation is $y=0.5x$

18.

$\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3$

Equation is $y=3x$

19.

$\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2$

Equation is $y=2x$

Find the equation of a line perpendicular to −x+y=−6 that contains the point (−4,5). Write the equation in slope-intercept form.

Lady bird [3.3K]

Answer:

y = -x + 1

Step-by-step explanation:

First, simplify -x+y=-6 to y = x - 6

Being perpendicular, then the x needs to be "flipped", making the slope y = -x

In order to have the slope go through (-4, 5), the line needs to intercept the y-axis at 1

Thus, the equation is

y = -x + 1
