Answers

Answer:

0.93

Step-by-step explanation:

what is the point-slope form of the line that has a slope of -4 and passes through Point -3, 1 ?
A y-(-3)= -4(x-1)
B y-1= -4 [x -(-3)]
C -1-y1 = -4 (-3-x1)
D 3-y1 = -4(1-x1)

Answers

y-1=-4(x+3)
So B is the correct answer. Just keep in mind that the original formula is y-y1=m(x-x1). With that formula, you can substitute any given information. I hope this helps!

A heron flies in a straight path for 5 min. at a constant rate of 2,000 ft. per min., and then flies another 6 min. at a constant rate of 3,000 ft. per min. How far does the heron fly during those 11 min.?

A. 22,000 ft.
B. 24,000 ft.
C. 26,000 ft.
D. 28,000 ft.

Answers

I believe it is ‘D’. 5 x 2000 = 10,000. 6x 3000 = 18,000. 18,000 + 10,000 = 28,000.
D

Explanation: 5 x 2000 = 10000
3000 x 6 = 18000
18000+10000= 28000

Answers

Answer:

D

Step-by-step explanation:

step 1: find the slope

slope is 2/-4 = -1/2

then plug in the value for x to y, you get +1 for the y intercept

then it becomes y=-1/2x + 1

I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!

Answer:

[tex]y=-\frac{1}{2} x+1[/tex]

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

SO

[tex]\frac{y_{1}- y_{2}}{x_{1}- x_{2}} \\\\=\frac{2-0}{-2-2}[/tex]

[tex]=-\frac{1}{2}[/tex] this is your slope

so now your equation is [tex]y=-\frac{1}{2} x[/tex] but it isnt done yet if we plug in one of the points we will find the y- intercept.

SO we find our y-intercept is 1 so that makes our equation [tex]y=-\frac{1}{2} x+1[/tex]

Hope this helps!

It took a boat 4 hours to travel downstream 120 miles. Upstream, the same trip took 6 hours. Find the rate of the current and the speed of the boat in still water.

Answers

Answer:

25 mph, 5 mph

Step-by-step explanation:

Speed of the boat = xSpeed of the current = y

Travel downstream, speed is:

x + y = 120/4 = 30

Travel upstream, speed is:

x - y = 120/6 = 20

Add up the equations:

x + y + x - y = 30 + 202x = 50x = 25

Find y:

y = 25 - 20 = 5

Speed of the boat is 25 mph

Speed of the current is 5 mph

The area of the square and rectangle are equal. If the side of the square is 50 cm, and the breadth (width) of the rectangle is 10 cm, find the length and perimeter of the rectangle.

Answers

Answer

The length would be 250cm and the perimeter would be 520cm

Explanation

So if one side of the square is 50 all are, therefore 50 x 50 is 2,500 and the area of square and rectangle are equal so you would divide 2500 by 10 and get 250.
