Answer:
Step-by-step explanation:
y= -3x+1
you use inverse operations, and since you want the y alone, you subtract 3x on both sides, giving you y= -3x+1
Answer:
1. vertical translation (the point goes straight up)
2. P'(0,7) (the translation was up five units and over 1 unit)
3. f(-2)=2(-2)^2-4= (all y values are 4) (0,4)
f(0)=2(0)^2-4= (all y values are -4) (0,-4)
f(1)=2(1)^2-4= (all y values are -2) (0,-2)
In 3 hours, at 10 mph, Albert travels 30 miles. In 10 minutes (1/6 hr), while his son overtakes him, he travels 10/6 miles more, placing him at 30 + 10/6 = 190/6 = 95/3 mi.
His son covers 95/3 mi in 1/6 hr, so he's moving at (95/3)/(1/6) = 190 mph.
Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
