Answer:
-1
Step-by-step explanation:
-2 divided by 2 = -1.
A negative divided by a positive equals a lesser negative.
If f(x)=0.5^x+1, then f(-2) is 5.

Answer:
y = -3x -1
Step-by-step explanation:
We can write the equation in slope-intercept form if we know the slope and the y-intercept.
The slope is ...
m = "rise"/"run" = (change in y)/(change in x)
We can see that the line passes through grid intersections at (x, y) = (0, -1) and at (1, -4). Between these two points, the change in y is (-4 -(-1)) = -3, and the change in x is (1 -0) = 1. Then the slope is ...
m = -3/1 = -3
One of the points we just used is the point where the line crosses the y-axis, at the y-intercept of -1. So, with slope -3 and y-intercept -1, the equation of the line is ...
y = mx +b . . . . . . slope m and y-intercept b
y = -3x -1
All we need to do is apply these points into the function themselves.
For point F, y = -0.25(4) = -1
For point G, y = -0.25(-8) = 0.25(8) = 2
Point F's y-coord is -1 and Point G's y-coord is 2.
Answer:
Equilateral triangle, isoceles triangle
It is also an acute triangle
Step-by-step explanation:
All sides are equal---which implies it is an equilateral triangle
Any two pairs of the given triangle's sides are equal-----which implies that it is isoceles
All angles are less than 90° ---which implies that all angles are acute
