What is the rate of change of y with respect to x for this function? How do I solve problems like this?

1 answer:

7 0

If i am doing this correct.

pick to points and use the distance formula\
Y2 - Y1
divided by
X2 - X1

so i picked the points
-2, 12
0, 3

this would mean
12-3
0-(-2)
which would be

9
2

so 9/2 it isn't possible so it would stay as 9/2 which is your answer.. C

Hope this helps.!!!!

Answer:

0 < y <= 6

Step-by-step explanation:

Given:

√(x² - 6x + 9)

if -3 <= x < 3

you can write (x² - 6x + 9)

as (x-3) * (x- 3) which is (x-3)²

so now you have √{(x-3)²}, which is the same as the absolute value of x-3. In mathematics it is written as:

| x - 3 |

So √(x² - 6x + 9) = | x - 3 |

See the graph in the attachment.

for -3 <= x < 3

you get the y values bigger then ( but not equal to) 0 and smaller then or equal to 6.

This is written as 0 < y <= 6

student found the slope of a line that passes through the points (1, 14)and (3, 4) to be 5. What mistake did she make?

vladimir2022 [97]

Y2-y1/x2-x1
(1,14) & (3,4)
y2= 4
y1=14
x2=3
x1=1

So....

(4-14)/(3-1) = -10/2 = -5

The answer should be negative instead of positive, she probably subtracted 4 from 14 instead.

80 - 9.38 = 70.62

41.54(.07) = 2.91

41.54 + 2.91 = 44.45

66(.07) = 4.62

66 + 4.62 = 70.62
