<em>Answer:</em>
I believe the answer would be 9,000 due to the fact that you can round the 7 in the hundreds place up. Turning the 8 into a 9.
Answer: x = 4
Step-by-step explanation:
6x - 3 = 21
Add 3 to the other side
6x = 24
Divide 24 by 6
x = 4
Answer:
sqrt(1/2x+6) = h^-1 (x)
Step-by-step explanation:
To find the inverse, we exchange x and y and then solve for y
y = 2x^2 -12
Exchange x and y
x = 2y^2 -12
Solve of y
Add 12 to each side
x+12 = 2y^2
Divide by 2
(x+12) /2 = 2y^2/2
(x+12)/2 =y^2
1/2 x+6 = y^2
Take the square root of each side
sqrt(1/2x+6) = sqrt(y^2)
sqrt(1/2x+6) = y
This is the inverse
Answer:
The answer is 18,900 Joules.
Step-by-step explanation:
If you work out the equation
Half of 350 is 175
12 squared is 144
6 squared is 36
Subtract 36 from 144 and get 108
108 multiplied by 175 is 18,900
Answer: Money required to save in 3 weeks =490–175 =315
Let y represent the money to be saved and x represent the money to be saved per week
Then x = y/3 or 3x = y is the equation
