Answer:
45.56
Step-by-step explanation:
Slope = (10 - 6)/(30 - 10) = 4/20 = 1/5
answer
1/5 is the slope
Answer:-2
Step-by-step explanation:
-y+2x=-1 needs to be changed to y=-2x-1 so that you can set the two equation equal to each other in order to solve for x. That makes it -2x-1=1/2x+4
-4= -4
-2x-5 = 1/2x
+2x = +2x
-5 = 2.5x
div. 2.5 div. 2.5
X= -2
Check: y= -2(-2)-1 Y=3
y=1/2(-2)+4 Y=3
Answer:
Step-by-step explanation:
If you'd graph this function on a graphing calculator or graphing utility, you'd see quickly that the graph never touches or crosses the x-axis. This tells us immediately that there are no real roots; all four roots are complex or imaginary.
Given:
The graph of a piecewise function.
To find:
The value of h(3).
Solution:
We have, the graph of a piecewise function h(x).
The function is divided into two pieces. One is over the interval 
and another one is over the interval 
.
From the given graph it is clear that the function passes through the point (3,1). It means the values of the function is 1 at x=3.
at x=3.
The value of h(3) is 1.
Therefore, the correct option is C.
