The answer would be d , because you have to add how many of each fish to equal up to the sum of 420 . which is x y . so the first equation is x + y = 420 . then it says he bought 6 times as many parrotfish as he did angelfish so you would have to multiply x which represents angelfish by 6 . to get the second equation of y = 6x .
Answer: y = 3/4x
Step-by-step explanation:
Each y-value output is 3/4 of the x-value inputted.
8 x 0.75 = 6
12 x 0.75 = 9
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.

The distance between the two points is 5.4
Explanation:
The points are (-1,-9) and (1,-4)
The distance between the two points can be determined using the formula
Substituting the values in the formula, we get,
Adding the values,
Squaring the terms, we get,
Simplifying, we have,
Thus, the distance between the two points is 5.4
Step-by-step explanation:
We know that we have the formula that F = ma
Given
Force (F) = 7.5 N
Acceleration (a) = 15 m/s²
Mass (m) = ?
Now
F = ma
7.5 = m * 15
m = 7.5/ 15
Mass = 0.5 kg
