Answer:
x = -1/24
Step-by-step explanation:
8 - 1/3x = 16
8 × 3x - 1/3x = 16
24x - 1/3x = 16
24x - 1 = 16 × 3x
24x - 1 = 48x
1 - 24x = - 48x
1 = 24x - 48x
1 = - 24x
-1/24 = x
x = -1/24
Using the point slope form y - y1 = m(x-x1)
m is the slope, because the lines are parallel the slope is identical, so m = -2.
Replace x1 and y1 with the given point and then solve for y:
y - 1 = -2(x-4)
Simplify:
y - 1 = -2x + 8
Add 1 to both sides:
y = -2x +9
Answer:
for the first answer your answer was correct, it was the second answer that was wrong. So the first answer is 2 3/4. The second answer would be 81 centimeters because it grew that much.
Step-by-step explanation:
To find the first answer add the starting height and ending height. To find how much it grew convert the total ending height of the tree to cm by multiply by 100, so 275. Then subtract 356 by 275 because you are finding out how much it grew. Take away 275 from 356 and you get 81
Because for input=-2 there are more than one outputs. It means the this is not a function and it’s impossible to find a rule.
Answer:
(4,-1), (3,-1),(2,-1) or (1,-1)
if you draw a horizontal line through the point (5,-1) you will notice it crosses through every point ending with -1
