Give the slope of the graph and the unit rate

Answers

Answer 1

Answer:

Answer:

y=5/4 x

The slope is 5/4

Step-by-step explanation:

To solve this problem we need to find the equation of the line, y=mx+b

We've been given a table with several points, so we can use two of them to perform our calculus.

To obtain the slope we need to use the equation of slopes:

$m=(y_(2)-y_(1))/(x_(2)-x_(1))$

Where (x1,y1) =(4,5) and (x2,y2)=(8,10)

m= (10-5)/(8-4)=5/4

To obtain b we can use the point (x2,y2)=(8,10) in the equation.

10=5/4 *8 +b

b=0

Hence our line has the following equation:

y=5/4 x

A cheetah can cover 50 yards in 5⁄2 seconds. How long will it take a cheetah at the same speed run 80 yards

Answers

$(2.5)/(50)$ = 0.05 seconds (1 yard every 0.05 second)

0.05 x 80 = 4

It'll take the cheetah 4 seconds to run 80 yards

no of yards covered in 1 sec is 50*2/5 = 20 yards
no of sec.taken to complete 80 yards is 80/20 = 4 seconds

please answer the area of rectangle is 24 cm Square if it's length is 5cm longer than its width find its length of the rectangle.

Answers

Length = 8
W = 3
With some simple trail and error we can arrive at this answer, since area is 24 (a small multiple) we can test numbers that are 5 apart 1,6 2,7 3,8 and multiply them and you will get answer

How to write 1.23,1.2,2.31,3.2 from least to greatest

Answers

from least to greatest it would be: 1.2, 1.23, 2.31, 3.2 I believe hope that helped

It's pretty simple actually, it's least to greatest? Then lets start out with the least, which means closest to 0:
1.2
1.23
Since 1.23 has more numbers in it, it is greater than 1.2, because 1.2 could also be written out as 1.20 and that is less than 1.23.

Now lets go with the greatest:
2.31
3.2
It's obvious 3.2 would be the greatest, so therefore:

1.2, 1.23, 2.31, 3.2
is from least to greatest.

Hope this helps!

The equation of a line is given below.
- 4x - 5y = -5

Answers

See the attached figure

Explanation:

I'll assume you need to get the graph of the following linear function:

$-4x-5y=-5$

So if you multiply all the equation by -1 you will get:

$4x+5y=5$

With two points we can graph the line of this equation, so:

$\bullet \ For \ x=0, \ then: \n \n (0)+5y=5 \n \n Solving \ for \ y: \n \n y=(5)/(5) \n \n y=1 \n \n Point: \ (0,1) \n \n \n \bullet \ For \ y=0, \ then: \n \n 4x+5(0)=5 \n \n Solving \ for \ x: \n \n 4x=5 \n \n x=(5)/(4) \n \n Point: \ (5/4,0) \n \n \n So \ our \ line \ passes \ through: \n \n (5,0) \ and \ (5/4,0)$

By using graphing tool we get the graph shown below.
