Answer:
12 million dollars.
Step-by-step explanation:
Let the sales in the first year be x million .
So the sales in the second year were x + 4 million, in the third year were 3(x + 4) and this is 48 million dollars.
So we have the equation 3(x + 4) = 48
3x + 12 = 48
3x = 36
x = 12 million dollars.
8.6*7=60.2, 16*1.4=22.4, 12*14=168, 7.3*20=146
Answer:
f(x) = 0.5(x + 3)^2 + 5.
Step-by-step explanation:
The horizontal stretch is given by multiplying by 1/2 or 0.5:
f(x) = 0.5x^2
Now a shift of 3 to the left gives f(x) = 0.5(x + 3)^2.
5 units up gives 0.5(x + 3)^2 + 5.
X=22
Area is found by multiplying (x+7)and (2x-1) together. 22+7=29, 2(22) -1 = 43, 43+29=72
