For this question you would need to use point-slope form which is: (y-y₁)=m(x-x₁) where m=slope and (x₁, y₁) is your point on the line. So you already have a point, (2,2) and you need slope which is the negative inverse of the slope of a line perpendicular to it. In this case, the slope would be -1/3. So if you plug all of this in the point-slope equation you get: y-2=(-1/3)(x-2) ------> y=(-1/3x)-(2/3)+2 ----------------->y=(-1/3x)+(4/3)
when you challange yourself and take risks then you will not only lean from what you did right but also what you did wrong.
Answer:
40 years old
Step-by-step explanation:
Let's imagine a+b=63
63-12=51 (since they were both 6 years younger)
A is double B
34+17=51
34/2=17
You need to add the 6 years back onto the mothers age - 34+6=40
40 years old
2160 inches into 12 pieces.
12 pieces = 2160 inches.
1 piece = 2160 / 12 = 180 inches.
But 12 inches = 1 foot, 3 feet = 1yard
3*12 = 36 inches = 1yard.
36 inches = 1yard.
180 inches = 180/36 = 5 yards.
Each piece was 5 yards long.
