Step-by-step explanation:
point-slope form means
y - y1 = m(x - x1)
(x1, y1) is a point on the function line (like the given (1, 4)).
m is the slope, weiss is the ratio of "y coordinate change / x circumstances change" when going from one point to another in the function line.
so, we need a second point. I suggest x = 0 (side length is 0), which makes also the perimeter 0 (4×0 = 0) : (0, 0)
then we see
x changes by +1 (from 0 to 1)
y changes by +4 (from 0 to 4)
the slope m is then +4/+1 = 4
and using the given point this makes the point-slope form
y - 4 = 4(x - 1)
Y=1x+3 because if the y intercept is 3 and it goes up 1 and right 1 you get a Parellel line to (7,7) and (3,3)
Answer:
a. 3
b. 6
and i got the last answer as 11
I am not too sure about the last one, sorry. Hope this helped!
Step-by-step explanation:
Answer:
(-2, 0)
Step-by-step explanation:
ƒ(x) <0 in the intervals where the function is below the x-axis.
The only interval where ƒ(x) < 0 is (-2.0, 0.0).
Let X be width <span>of a rectangle, then
(x+8) - </span><span>length
(x+x+8)*2 = 52
x+x+8 = 52/2
2x+8 = 26
2x = 26-8
2x = 18
x = 18/2
x = 9 cm
Answer: 9 cm.</span>
