So for something to be perpendicular the gradient must be the negative reciprocal of your original line so your original gradient is 2 so your new gradient will be -1/2. Then you have y = -1/2 x + c . Now you substitute this into the point (4,-1) to get -1 = -1/2 x 4 + c and -1/2 x 4 = -2 so you have -1 = -2 + c so c = 1 so then you put the equation together to get y = -1/2 x + 1
Hope this helps :))
Answer:
Step-by-step explanation:
Lets get the equation for the graphed function
<u>Using two points: </u>
Y-intercept is known, it is -6 as per the first point
<u>Slope is:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (0+6)/(3-0) = 6/3= 2
<u>So the function f is:</u>
<u>g(x) is going to be</u>
- g(x) = -1/2f(x + 2) = -1/2 (2(x+2) - 6) = -1/2(2x + 4 - 6) = -1/2(2x - 2) = - x + 1
So
<em>The graph is attached</em>
Answer:
–21.87 ÷ 4.79
≈ -20 ÷ 5
≈ -4
Step-by-step explanation:
front end estimation means to round off to the most left digit.
eg 12 ≈ 10
75
