Answer:

A 7.81

Step-by-step explanation:

Use the distance formula to find the distance between coordinates.

d = √((2--4)^2 + (5-0)^2) \nd = √((2+4)^2 + (5)^2) \nd = √((6)^2 + (5)^2) \nd = √(36 + 25) \nd = √(61) \nd=7.81

Step-by-step explanation:

Write an equation for L in point slope form L is parallel to y=5x. points (1,-1)

Answers

Answer:

y + 1 = 5(x - 1)

Step-by-step explanation:

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

Parallel lines have the same slope.

We have y = 5x → m = 5.

The point-slope form:

y-y_1=m(x-x_1)

We have the slope m = 5 and the point (1, -1). Substitute:

y-(-1)=5(x-1)\n\ny+1=5(x-1)

Answer:

y + 1 = 5(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

given y = 5x with slope m = 5

• Parallel lines have equal slopes

for line L with m = 5 and (a, b) = (1, - 1) then

y + 1 = 5(x - 1) ← in point- slope form

Laura and Brent paddled a canoe 6 miles upstream in four hours. The return trip took three hours. Find the rate at which Laura and Brent paddled the canoe is still water.

Answers

Call the rate in still water vs;
upstream you have: vs-v=6/4
downstram you have: vs+v=6/3
where v is the rate with which the river flows.
rearranging:
vs-v=3/2
vs+v=2
from the second you have v=2-vs substitute into the first:
vs-2+vs=3/2
2vs=7/2
vs=7 mi/hr
