Write an equation of the line that passes through the points (-2, -3) and (1, -3)._____________ What is the slope?___
Gre4nikov [31]

Answer:

y = -3, slope = 0

Step-by-step explanation:

1) First, find the slope of the line. Substitute the x and y values of the given points into the slope formula, m  = \frac{y_2-y_1}{x_2-x_1}, and solve:

m = \frac{(-3)-(-3)}{(1)-(-2)} \\m = \frac{-3+3}{1+3} \\m = \frac{0}{4} \\m = 0

Thus, the slope is 0.

2) If a line has a slope of 0, that means it is horizontal. All horizontal lines are represented by the equation y = a number. That number is determined by the y-value of all the points the line intersects. Thus, find the y-value of the given points and put it into the equation. Looking at the given points, that number would be -3, so y = -3 is the equation.

At start:   PE only

At end:  KE and energy lost to friction


PE = KE + E
E  = PE - KE
    = mgh - (1/2)mv^2
    = (40)(9.8)(12) - (.5)(40)(10)^2
    = 2704J

PLEASE HELP. Which is the best interpretation of the solution set for the compound inequality? 3/2x-1<2x + 4 or 3(2/3x + 1) &
Fudgin [204]
(3/2)x-1<2x+4
3x-2<4x+8
-2<x+8
-10<x
x>-10

3((2/3)x + 1) < 11
(3*2/3)x+1*3<11
2x +3<11
2x<8
x<4

so the compound equality is the set of all numbers which are >-10 or <4, which are D) all real numbers
