Multiply 5 by 4.22 because 5 cups of water is 4.22 liters
ANSWER
x coordinates of the intersection points
EXPLANATION
The given system of equations is:
We want to use the graph of these functions to solve
The point of the intersection of the graph gives the solution to the simultaneous equation above.
Hence the x-coordinates of the intersection points gives the solution set of
The last choice is correct.
Answer:
xy = 1
k = 79
Step-by-step explanation:
Question One
The first and third frames look to me to be the same. I'll treat them that way.
y = x^2 Equate y = x^2 to the result of 2y + 6 = 2x + 6
2y + 6 = 2(x + 3) Remove the brackets
2y + 6 = 2x + 6 Subtract 6 from both sides
2y = 2x Divide by 2
y = x
Now solve these two equations.
so x^2 = x
x > 0
1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is
x(x) = x Divide both sides by x
x = 1
y = x^2 Put x = 1 into x^2
y = 1^2 Solve
y = 1
The second solution is
(1,1)
xy = 1*1
xy = 1
Answer: A
Question Two
square root(k + 2) - x = 0
Subtract x from both sides
sqrt(k + 2) = x Square both sides
k + 2 = x^2 Let x = 9
k + 2 = 9^2 Square 9
k + 2 = 81
k = 81 - 2
k = 79
Answer:
20 + 5m = 140
$24 on each day of the last five days
Step-by-step explanation:
Total amount to spend in 6 days = $140
He spent:
First day = $20
Balance = Total amount to spend - Amount spent on first day
= $140 - $20
= $120
He spent the same amount of money during the next five days.
Amount spent each day in the last 5 days = Balance / 5 days
= 120 / 5
= 24
Amount spent each day in the last 5 days = $24
The equation is
20 + 5m = 140
Where,
m = amount spent in the last five days
20 + 5m = 140
5m = 140 - 20
5m = 120
m = 120 / 5
m = $24
