Answer:

Step-by-step explanation:

let it passes through (-1,y1) and (2,y2)

slope=\frac{y2-y1}{x2-x1} =\frac{y2-y1}{2-(-1)} =\frac{y2-y1}{3} \\eq. ~of~line~is~\\y-y1=\frac{y2-y1}{3} (x+1)\\3y-3y1=xy2-xy1+y2+y1\\3y=(y2-y1)x+y2+4y1

════════════════════

Answer:

↝r =  \frac{471}{25\pi}

Solution:

2\pi r = 37.68

\frac{2\pi r}{2\pi}  =  \frac{37.68}{2\pi}

r =  \frac{37.68}{2\pi}

r =  \frac{471}{25\pi}

3x+2-5x=10 what is X
Advocard [28]

Answer:

x = -4

Step-by-step explanation:

Solve for x:

3 x - 5 x + 2 = 10

Grouping like terms, 3 x - 5 x + 2 = 2 + (3 x - 5 x):

2 + (3 x - 5 x) = 10

3 x - 5 x = -2 x:

-2 x + 2 = 10

Subtract 2 from both sides:

(2 - 2) - 2 x = 10 - 2

2 - 2 = 0:

-2 x = 10 - 2

10 - 2 = 8:

-2 x = 8

Divide both sides of -2 x = 8 by -2:

(-2 x)/(-2) = 8/(-2)

(-2)/(-2) = 1:

x = 8/(-2)

The gcd of 8 and -2 is 2, so 8/(-2) = (2×4)/(2 (-1)) = 2/2×4/(-1) = 4/(-1):

x = 4/(-1)

Multiply numerator and denominator of 4/(-1) by -1:

Answer:  x = -4

What is the rate of change of the function?
Alona [7]

We have been given that on a coordinate plane a line with negative slope passes through points (0,1) and (1,-1). We are asked to find the rate of the change of the function.

We know that slope represents rate of change of function.

We will use slope formula to solve our given problem.

m=\frac{y_2-y_1}{x_2-x_1}

Let (x_1,y_1)=(0,1) and (x_2,y_2)=(1,-1).

m=\frac{-1-1}{1-0}

m=\frac{-2}{1}

m=-2

Therefore, the rate of change of the given function is -2.

Answer:

8.2

Step-by-step explanation:

If each student in the group collected 15 shells, we know that there are 123 students on the field trip, so we can take 123 and divide it by 15 to get 8.2 or 41/5.
