Sounds as tho' all three lines are parallel. Is that correct?
If so, all three lines have the same slope!
What is the slope of <span>5y=2x-20 ? Solving for y, y = (2/5)x - 4
</span>
The slope is (2/5).
Now find the equation of the line with slope (2/5) that passes thru (10,-8).
It is y - [-8] = (2/5)(x - 10).
We can simplify this, with the result y + 8 = (2/5)x - 4. This, in turn, can be simplified to y + 8 = 2x/5 - 4, or y = 2x/5 - 12. Mult. all terms by 5 to eliminate the fraction:
5y = 2x - 60
Note how this has the exact same form as the given 5y = 2x - 20, EXCEPT that the constant at the end is different.
5y = 2x - 60 and 5y = 2x - 20 are parallel lines with the same slope but different y-intercepts.
4/12 of the fans are kids because 1/4 can be multaplied by 3 to get 3/12
Is it 33 or 3.3 sorry if wrong!
Answer:
A. (1, 0)
Reason:
When the first equation is graphed: y <u><</u> x + 1, the left side of the line is shaded and when the second equation is graphed: y <u><</u> x^2 -3x, the bottom is shaded.
The green section does not contain solutions. So D is automatically out.
The red section does not contain solutions as well. So C is automatically out.
For choice B, the point goes out of the shaded blue section, so that's out also.
As for choice A its in the blue shaded section, which makes that answer correct.
(when the two equations are within each other and combine a color, then whatever points is within the shaded part is the right answer)
