Answer:
there's no graphed pictured. but slope is rise/ run so just count the boxes between the points on the line. Up and down is the numerator and sideways is the denominator. If its decreasing from left to right it's negative, and if it's increasing left to right then it's positive
F−1(x)=4x+48 is your answer
The answer would be the second one
Answer:
x = 2
Step-by-step explanation:
- You would find a value of y to plug into either of the equations. For example, I chose the equation 2x - y = 6. When I set it equal to y, I got y = 2x - 6
- Now that I know what y is equal to, I plugged it into the second equation to get 5x + 10 (2x - 6) = -10
- You then would calculate for x.
- Your end result should be x = 2, which is the point that the two equations intersect
This works because the two equations are set equal to each other, making them share a common value between them.
You can also plug both of these equations into a graphing calculator, and on the graph select the command to calculate the intersection.
Hope this helped!
