Answer:
Hi there!
The correct answer is:
a. 27831.05
Step-by-step explanation:
Since they gave you the equation for the line of best fit: y = 1.9x + 21
a. solve for x: 52900= 1.9x + 21
minus 21 on both sides to get 1.9x = 52879
then divide 1.9 on both sides to get x= 27831.05
7x+3(x-2)4x+8=

Distributive property
7x + 3x - 6 -4x + 8
Combining like terms
10x - 6 -4x + 8
6x - 6 + 8
Combine numbers
6x + 2 </span>
Hope i helped:D
Answer:
2.34 grams
Step-by-step explanation:
The first 3 digits of the number are 2, 3, 3. The next digit is 5, which is more than 4, so 1 is added to the digit to its left and all digits to the right of the first three are dropped.
2.33 becomes 2.34 because of the 5 in the thousandths place.
Your rounded measurement is 2.34 grams.
Answer:
y+3x+11=0
Step-by-step explanation:
m=-3, x1=-4, y1=1
from m=y-y1/x-x1
-3=y-1/x-(-4)
-3(x+4)=y-1
-3x-12+1=y
y=-3x-11
y+3x+11=0
