Set each set of parentheses to 0 and solve for the x’s
X-1= 0
Add 1 to both sides
X =1
X-7 = 0
Add 7 to both sides
X = 7
The zeros are 1,7
To plot them make dots at (1,0) and (7,0)
Answer:
228 hydrogen atoms
Step-by-step explanation:
In a water molecule,
1/3rd is oxygen atoms, and
2/3rd (1 - 1/3 = 2/3) is hydrogen atoms
If there are 114 water molecules,
Total number of atoms would be:
3 * 114 = 342 (1 oxygen and 2 hydrogen atoms in 1 water molecule)
Out of these, 2/3rd would be hydrogen atoms, so:

There would be 228 hydrogen atoms
Answer:
x = -9
Step-by-step explanation:
-4x = -1/2(10x + 18)
Distribute
-4x= - 5x -9
Add 5x to each side
-4x+5x = -5x+5x -9
x = -9
So in this equation we're given that Ravi puts $350 into his account, this means that when W=0, S=350. Or that the y-intcpt(b) is 350.
when we find an equation we use slope intcpt formula:
y = mx + b
M in this case is the slope or the amount S
changes for every value of W. So if Ravi adds $70 every day that means the amount of money in his account increases by $70 everyday, so we can say m= 70
So putting together the equation with b= 350 and m = 70 we get :

Calculating for 17 weeks or W = 17
