Answer:
(-1, 1)
Step-by-step explanation:
I used a graphing tool to graph the equations. When graphed, they cross at coordinate (-1, 1). Therefore, (-1, 1) is the solution.
Answer:
Option 2
Step-by-step explanation:
If you multiply 2 by 2 you get 4. If you multiply 3 by 2 you get 6. If you multiply 4 by 2, you get 8. If you multiply 5 by 2 you get 10. A proportional relationship is where you can multiply all the numbers by a certain number to get the answer. In this case, all the numbers in the left column could get multiplied by 2 to get the number in the right column.
Answer:
478.5
Step-by-step explanation:
Considering the fact that the 2 after the g is not a power, then
400 x 0.6 x 2 = 480
0.9/0.6 = 1.5
480 - 1.5 = 478.5
The initial value of the graph is where
. Thus, in this case, the initial value is 12.
The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:
![\dfrac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%5Cdfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
and
are points on the graph
Let's use two points from the chart to find the slope:
![m = \dfrac{30 - 21}{2 - 1} = 9](https://tex.z-dn.net/?f=m%20%3D%20%5Cdfrac%7B30%20-%2021%7D%7B2%20-%201%7D%20%3D%209)
In this case, the rate of change of the graph is 9.
