Step-by-step explanation:
here's the answer to your question
Answer: --42
Step-by-step explanation:
All that you have to do in this equation is substitute the value of x given with the x's in the expression. SO...
Expression: -4(5x+2) - 6(x-3)
Substitute: -4(5(2)+2) - 6((2)-3)
Solve: -4(10+2) - 6(-1)
-4(12) - 6(-1)
-48 +6
Answer: -42
Hope this helps!
The equation of a line of the slope-intersection form is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It's the slope
b: It is the cut-off point with the y axis
If two lines are parallel then their slopes are equal.
We have the following line:
![10x + 2y = -2\\2y = -10x-2\\y = -5x-1](https://tex.z-dn.net/?f=10x%20%2B%202y%20%3D%20-2%5C%5C2y%20%3D%20-10x-2%5C%5Cy%20%3D%20-5x-1)
Thus, the slope of the line is -5.
Therefore a parallel line is of the form:
![y = -5x + b](https://tex.z-dn.net/?f=y%20%3D%20-5x%20%2B%20b)
We replace the point ![(0,12)](https://tex.z-dn.net/?f=%280%2C12%29)
![12 = -5 (0) + b\\12 = b](https://tex.z-dn.net/?f=12%20%3D%20-5%20%280%29%20%2B%20b%5C%5C12%20%3D%20b)
Finally, the equation is of the form:
![y = -5x + 12](https://tex.z-dn.net/?f=y%20%3D%20-5x%20%2B%2012)
Answer:
![5x + y = 12](https://tex.z-dn.net/?f=5x%20%2B%20y%20%3D%2012)
3/4 * 3/4
Three quarter meaning 3/4
Of represents *
So the answers is (3*3)/(4*4)=9/16 or 0.5625
