From my thinking don’t use this one because I’m not really answering 5-2=3=3
The answer is C because 51×-2=-102 and 51×-0.5=-25.5
So it -102+(-25.5) or C
Answer:
So for the geometric mean, you would multiply the two numbers and put them under a radical

Answer: Y = -2x + 10
Step-by-step explanation:
You can find the slope by using the slope formula
which is y2 - y1 over x2 - y1
4 - 2 = 2
3 - 4 = -1 so the slope is -2/1 or just -2x
Now to find b we plug in any 2 points
0 = -2(5) + b
0 = -10 + b
add 10 to both sides so -10 cancels out
10 = b
or
b = 10 (same thing)
so the equation would be
y = -2x + 10
Answer:
80 persons haf fish and 152 persons had chicken
Step-by-step explanation:
Given data
let the number of persons that had fish be x and chicken be y
so
12x+9y=2544------------------1
x+y= 232------------------------2
from 2
x= 232-y
substitute the value of x in 1
12(232-y)+9y=2544
2784-12y+9y=2544
2784-3y=2544
3y= 2784-2544
3y=240
y= 240/3
y=80
put y= 80 in 2
x+80= 232
x= 232-80
x=152
Hence 80 persons haf fish and 152 persons had chicken
