Choice B
Step-by-step explanation:
Answer: x+7
Step-by-step explanation:
g(x) = 4x - 2
g(x+7)=4(x+7)-2
Substitute (x+7)
Answer:
- y = 1.8x +53.7
- 73.5 in 2005
Step-by-step explanation:
The 2-point form of the equation of a line is useful here. It tells you that for the points (x1, y1) and (x2, y2) the line can be written as ...
y = (y2 -y1)/(x2 -x1)(x -x1) + y1
For your given points, this is ...
y = (60.9 -57.3)/(4 -2)(x -2) +57.3
y = 1.8(x -2) +57.3
y = 1.8x +53.7 . . . . . simplify
__
For x = 11 (in 2005), the predicted value is ...
y = 1.8·11 +53.7
y = 73.5
You have to show your equation, pls!
For 7., you have to add 3 to both sides to cancel out like terms, so you'll end up with:
x/8=10
Then cross multiply, you'll get x=80.
For 9., add 2n to both sides and subtract 2 from both sides to get 39=3n. Divide both sides by 3 to get n= 13. Hope this helps!
