Answer:
5 × 
Step-by-step explanation:
Here, we are required to determine the solution to the equation: 13.7y = 6.2y + 30?
The solution to the equation is y = 7.5
The solution is thus,
- 13.7y = 6.2y + 30
- 13.7y - 6.2y = 30
- 7.5y = 30
Therefore, y = 30/7.5 = 4
Therefore, y = 4 is the solution to the equation.

In order to utilize the graph, first you have to distinguish which graph accurately pertains to the two functions.
This can be done by rewriting the equations in the form y = mx + b which can be graphed with ease; where m is the slope and b is the y intercept.
-x^2 + y = 1
y = x^2 + 1
So this will be a basic y = x^2 parabola where the center intercepts on the y axis at (0, 1)
-x + y = 2
y = x +2
So this will be a basic y = x linear where the y intercept is on the y axis at (0, 2)
The choice which depicts these two graphs correctly is the first choice. The method to find the solutions to the system of equations by using the graph is by determining the x coordinate of the points where the two graphed equations intersect.
Answer:
The difference between them will be 6.
Step-by-step explanation:
When they went for their first round of cycling, which was 45 minutes, it was already a distance of 3 miles adding another 6 to Han's miles and another 9 to Claire's miles it would give you 18 and 12 and 18 minus 12 is 6.
Therefore, it was doubled from the distance only being 3 miles to 6 miles.
Answer:
( 1, -2)
step-by-step explanation:
- original coordinates of C: (4, -2)
if reflected over y-axis: use the formula: (x,y) → (-x,y)
- new coordinates: (-4, -2)
then if translated 5 units horizontally, there will be change in x axis:
- new coordinates: (-4+5, -2) → ( 1, -2)
