Answer : option D
we need to find out the graph shows a mixed-degree system with exactly one solution
The solution of two graphs will be the intersection of two graphs
In the first graph,
There is no intersection of both circles, So no solution
second graph,
The circle intersects the parabola at two point, so two solution for this graph
Third graph,
The circle and line does not intersects, so no solution
Fourth graph,
Both parabola intersects at one point, so one solution for this graph
So option D has exactly one solution
Answer:
The table represents a proportional relationship
Step-by-step explanation:
Given
x ------ y
1 ------- 15
2 --------30
4 ---------60
5 -------- 75
Required
Determine if the table shows a proportional relationship
To check this, we make use of the following formula;
Where k is the proportionality constant
When x = 1, y = 15
When x = 2, y = 30
When x = 4, y = 60
When x = 5, y = 75
Since the value of k for all values of x and y is the same; i.e. 15
Then, the table represents a proportional relationship
Answer:
6 pounds of coffee
Step-by-step explanation:
Given Teresa's $90 gift card for a coffee store, and a balance of $38.46 on her card:
Subtract the remaining balance of $38.46 from the $90 original balance on Teresa's card, to determine how much she spent on coffee.
$90.00 - $38.46 = $51.54
Next, divide the amount that she spent at the coffee store by the $8.59 cost per pound to find out how many pounds of coffee she purchased from the store:
$51.54 ÷ $8.59 per pound = 6 pounds
Therefore, she bought 6 pounds of coffee worth $51.54 from the store.
