1 is the answer coz1*3:2*2 = 3:4=3/4:1
The correct answer is D. 40
Answer:
3x-y=-2
Step-by-step explanation:
9x-5x-x-3y+2y=-2
3x-y=-2
Number of calories consumed on Monday = 2161
Number of Calories consumed on Tuesday = 2378
Number of Calories consumed on Wednesday = 1841
Daily average intake is 2200
Let calories intake on Thursday be X
Now ,
Average = sum of total calories/ number of calories
=> 2200 = 2161+2378+1841+X/4
=> 2200 x 4 = 6377 + X
=> 8800 = 6377 + X
=> X = 8800-6377
=> X = 2423
So Samuel must consume 2423 calories on Thursday
F(x)= -8x²
f(-3)= -8* (-3)²
f(-3)= -8 * 9
f(-3)= -72
