We can compare g(x) with f(x) by looking at the b and c values of f(x+b)+c. Let's start with the b value. Remember that when horizontally shifting a function, if c is greater than 0, it shifts it to the left. So, in this case, g(x) is shifted 4 units left. Now, let's look at the c value. It is 2, meaning it shifts up in that direction. The correct answer is D, it was shifted 4 units left and 2 units up.
Let x=grams of 70% alloy:
0.70x+16×0.20=0.30(x+16)
0.70x=0.30x+4.8-3.2
0.40x=1.6
x=1.6/0.4=16/4=4g
4 grams of 70% alloy are needed.
Answer:
1.95
Step-by-step explanation:
area = (1/2 ×1 ×1 )×3 = 1.5 ( for sides)
area = ( 1/2 ×1 ×0.9) = 0.45 for base
area =1.5+0.45 = 1.95

Answer:
IQR=5+2=7 because you have to find the median and the median below the median and above the median to get 5 and a negative two and 5 subtract a negative is the same as adding a positive so then you get 7.
