Step-by-step explanation:
Now you can make a table to know the graph
- x =0 then y = -2
- x= 4/3 then y = -1
- x= 1 then y = -1.25
- x=2 then y=-0.5
- x=3 then y=0.25
attention : be careful the second photo is
inverted , open it and look to x-axis to know how is the graph
Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
Step-by-step explanation:
Let x = Number of weeks.
As per given question ,
Weight of Frank after x weeks = 160+2x (pounds)
Weight of John after x weeks = 208-3x (pounds)
When Weight of Frank= Weight of John
Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds
Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds
Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
Answer:
The point C(x, y) after the reflection of the point (x,y) across the y-axis will become:
C(x, y) → C'(-x, y)
Step-by-step explanation:
We know that the reflection of the point (x,y) across the y-axis is
the point (-x,y).
In other words, when a shape or object is reflected across the y-axis, the y-coordinate remains the same, but the sign of x becomes the opposite.
For example,
The point C(x, y) after the reflection of the point (x,y) across the y-axis will become:
C(x, y) → C'(-x, y)
If let suppose the coordinates of the original point C(1, 2), then after the reflection of the point C(1, 2) across the y-axis, the new coordinates of C would be transformed such as:
C(1, 2) → C'(-1, 2)
