Answer:

The slope of line through (2, 4) and (5, 1) is Negative

The slope of line through (3,5) and (-1,2) is Positive

The slope of line through (-7, 8) and (-7,0) is Undefined

The slope of line through (6.-3) and (4, -3) is Zero

Step-by-step explanation:

Slope is defined as the steepness of a line.

Slope is denoted by m and the formula for calculating slope is:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) and (x2,y2) are coordinates of the points through which the line passes

Now,

For (2, 4) and (5, 1):

[tex]m = \frac{1-4}{5-2} = \frac{-3}{3} =-1[/tex]

NEGATIVE

For (3,5) and (-1,2)

[tex]m = \frac{2-5}{-1-3} = \frac{-3}{-4} = \frac{3}{4}[/tex]

POSITIVE

For (-7, 8) and (-7,0)

[tex]m = \frac{0-8}{-7+7} = \frac{-8}{0}[/tex]

UNDEFINED

For (6.-3) and (4, -3)

[tex]m=\frac{-3+3}{4-6} = \frac{0}{-2} = 0[/tex]

ZERO

Hence,

The slope of line through (2, 4) and (5, 1) is Negative

The slope of line through (3,5) and (-1,2) is Positive

The slope of line through (-7, 8) and (-7,0) is Undefined

The slope of line through (6.-3) and (4, -3) is Zero

Answer:

x=-1

Step-by-step explanation:

plug in zero for y

y= -1/2x -2

0= -1/2x-2

2= -1/2x

-1=x

Answer: 1/10

Step-by-step explanation:

I think you mean 3/5 - 1/2?

we need to make the denominators the same, so we find the LCM of 5 and 2, which is 1, so we multiply them to get a common denominator of 10.

Now we multiply 3/5 by 2/2 to get 6/10, and 1/2 by 5/5 to get 5/10.

6/10 - 5/10 = 1/10

Step-by-step explanation

We're adding 25 and 8 together to get our answer, which would be 33 at the end.

Answer:

Step-by-step explanation:

Using the formula for finding the circumference of a circle.

C = 2πr

r is the radius

radius = diameter/2

radius = 10/2

radius = 5in

C ,= 2(3.14)(5)

C = 20(3.14)

C = 31.4×2

C = 62.8in (for 1 rotation)

For 16 rotations;

C = 16×62.8

C = 1004.8in

The distance covered is 1004.8in

Answer:

Perimeter is 302 meters

Step-by-step explanation:

Recall that the formula for the perimeter of a rectangle of length L and width W is given by:

Perimeter = 2 * L + 2 * W

so in our case, since L = 115 and W = 36, we get:

Perimeter = 2 * 115 + 2 * 36 = 230 + 72 = 302 meters

Answer:

302m^2

Step-by-step explanation:

rectangular parking lot is 115 meters long

36 meters wide.

Solution

Perimeter of the park=2(length+width)

=2((115+36)

=2×151

=302m^2

So permiter is 302m^2

Answer:

y=4

Step-by-step explanation:

y+3=7. take 3 off and also off the 7 then you get 4 which is the ansew as 3+4 equals 7 it is simple algebra substitute

-3. -3

7-3=4

Answer:A. 5m + 40

see in the picture, u can see that the line passes through (0;40) and (10;90)

suppose: the equation of the line is y = am + b (a ≠ 0)

because the line passes through (0;40) => 40 = b

the line passes through (10;90)              => 90 = 10a + b

=> b = 40

    a = 5

=> y = 5m + 40

Answer:

16

Step-by-step explanation:

Plug things in then use PEMDAS:

m * (7+9) * n

= 0.5 * (7+9) * 2

= 0.5 * 16 * 2

= 16

Step-by-step explanation:

=m(7+9)n

putting value of m&n

=0.5(7+9)2

=8×2

=16 ans

Answer:

(2/3)

Step-by-step explanation:

-2y = 3x + 7

y = 3/-2 + 7/-2

y = (-3/2) + (-7/2)

find the reciprocal of the slope (-3/2) which gets you the perpendicular slope of (2/3)
