Answer:
Graphs behave differently at various x-inter cepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Suppose, for example, we graph the function. f(x) = (x+3)(x - 2)²(x+1)³.
Notice in the figure below that the behavior of the function at each of the x-intercepts is different.
Answer: x1 = 251/26, x2 = -111/26
Step-by-step explanation:
Hi!
As you can see in the figure, the point you are looking for is the intersection of two lines.
The intersection point is found solving this system of linear equations (the point must satisfy both equations):
![9x_1 +7x_2=57\\4x_1 + 6x_2 = 13](https://tex.z-dn.net/?f=9x_1%20%2B7x_2%3D57%5C%5C4x_1%20%2B%206x_2%20%3D%2013)
You can solve it, for example, by the method of substitution:
![\text{solve for x1 in the first equation:}\\x_1 = \frac{1}{9}(57 - 7x_2)](https://tex.z-dn.net/?f=%5Ctext%7Bsolve%20for%20x1%20in%20the%20first%20equation%3A%7D%5C%5Cx_1%20%3D%20%5Cfrac%7B1%7D%7B9%7D%2857%20-%207x_2%29)
Then plug x1 into equation 2, and solve for x2:
![\frac{4}{9}(57-7x_2) + 6x_2 = 13\\\text{doing the algebra you get:}\\x_2 = \frac{-111}{26}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9%7D%2857-7x_2%29%20%2B%206x_2%20%3D%2013%5C%5C%5Ctext%7Bdoing%20the%20algebra%20you%20get%3A%7D%5C%5Cx_2%20%3D%20%5Cfrac%7B-111%7D%7B26%7D)
Then you use the value of x2 to get x1:
![x_1 = \frac{1}{9}(57 - 7x_2)= \frac{1}{9}(57 + 7*\frac{111}{26}) = 251/26\\](https://tex.z-dn.net/?f=x_1%20%3D%20%5Cfrac%7B1%7D%7B9%7D%2857%20-%207x_2%29%3D%20%5Cfrac%7B1%7D%7B9%7D%2857%20%2B%207%2A%5Cfrac%7B111%7D%7B26%7D%29%20%3D%20251%2F26%5C%5C)
35.3 = d - (-2.81)
Double negative = positive
35.3 = d + 2.81
Now subtract 2.81 on both sides
32.49 = d
Answer: 77.9
Step-by-step explanation: I just put it in my calculator lol
Answer:
1.) B
2.) B
Step-by-step explanation:
Number 1 is B bc rapid population in Mexico is caused by the economy improving.
Number 2 is B bc if there was one political party , there would be little opposition in the government. It basically means disaster.
