Answer:
20
Step-by-step explanation:
Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)
Area of a square = (side)² = (√20)² = 20 units²
This can occur through a parabola that has zeroes at x = 3 and x = -3. There is no rate of change because the y values do not change at those points because they are both 0. Karly can be correct because that turning point can be a vertex of a parabola. The parabola's function would increase until it reaches it's highest point and then go back down again. In this way, Karly and Tucker can both be correct.
Hope this helps :)
Answer:
Taji has a total of 56 quarters.
Step-by-step explanation:
Let <em>x</em> be the number of quarters that Taji has.
Amount in terms of quarter 
Let <em>y</em> be the number of dimes that Taji has.
Amount in terms of quarter 
As per question statement:
Total amount is $18.20 as given in the question statement.
Solving equations (1) and (2):
Multiplying equation (1) by 10 and subtracting from equation (2):
<em>x </em>is the number of quarters that Taji has.
So, Taji has a total of 56 quarters.
Answer:
It will cost Emily $40 to rent the bike for 6 hours.
Step-by-step explanation:
SOLUTION:
Total cost equals = (cost per hour × number of hours) + initial bike cost.
Let, y be total cost and x = renting a bicycle for x hours.
y=5x+10
To calculate Emily's cost for 6 hours, let x=6.
y=5(6)+10
y=30+10
y=40
It will cost Emily $40 to rent the bike for 6 hours.
