Answer:
(2, 6)
Step-by-step explanation:
Because 8(2)-2(6)=16-12=4.
Answer:
The larger angle is 144 degrees and the smaller angle is 36 degrees
Step-by-step explanation:
Because this is a supplementary angle you have to find out what x is to solve this equation ![2.4x+9.6x=180](https://tex.z-dn.net/?f=2.4x%2B9.6x%3D180)
Because 2.4x and 9.6x are like terms we add them ![2.4x+9.6x=12x](https://tex.z-dn.net/?f=2.4x%2B9.6x%3D12x)
So now to find x we divide 180 by 12 to get 15
We replace the x with 15 ![2.4(15)+9.6(15)=36+144](https://tex.z-dn.net/?f=2.4%2815%29%2B9.6%2815%29%3D36%2B144)
We add 36 and 144 which equals 180
Answer:
(-1,-4)
Step-by-step explanation:
the X can't repeat bc if it does it won't be a function
Answer: The required x-intercept of the given line is ![\left(-\dfrac{15}{13},0\right).](https://tex.z-dn.net/?f=%5Cleft%28-%5Cdfrac%7B15%7D%7B13%7D%2C0%5Cright%29.)
Step-by-step explanation: We are given to find the x-intercept of the line with the following equation :
![13x+y=-15~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)](https://tex.z-dn.net/?f=13x%2By%3D-15~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%28i%29)
We know that
x-intercept of a line is a point on the line where the line crosses the x-axis, that is y co-ordinate is 0.
Substituting y = 0 in equation (i), we get
![13x+y=--15\\\\\Rightarrow 13x+0=-15\\\\\Rightarrow 13x=-15\\\\\Rightarrow x=-\dfrac{15}{13}.](https://tex.z-dn.net/?f=13x%2By%3D--15%5C%5C%5C%5C%5CRightarrow%2013x%2B0%3D-15%5C%5C%5C%5C%5CRightarrow%2013x%3D-15%5C%5C%5C%5C%5CRightarrow%20x%3D-%5Cdfrac%7B15%7D%7B13%7D.)
Thus, the required x-intercept of the given line is ![\left(-\dfrac{15}{13},0\right).](https://tex.z-dn.net/?f=%5Cleft%28-%5Cdfrac%7B15%7D%7B13%7D%2C0%5Cright%29.)
The answer is all real numbers because -2x-6=-2x-6
