Answer:
1/3
Step-by-step explanation:
the multiplication of 2 lines perpendicular is - 1
then if x is the slope you are looking for
x * - 3 = - 1
x = 1/3
F (x)=7-3x it is the linear funtion of th is on
The values would be F(x)=-8
Answer:
- Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
And
In three years, the sum of their ages will be 30 years:
We got two equations.
Simplify and solve by substitution:
- 3x - 4 + x = 24 Substitute y
- 4x - 4 = 24
- 4x = 28
- x = 7
Find y:
