Hello ;
<span>A line contains the point (0,0) : y=ax a is aslope
a = (yb -yO)/(xb -xO) B(1;4) O(0;0)
a = (4-0)/(1-0)=4
</span><span>all the equations that represent this line is : y = 4x or y-4x = 0</span>
Answer:
yes
Step-by-step explanation:
So basically we have to solve 100 = -x² + 10x + 300 for x.
x² - 10x - 200 = 0
(x - 20)(x + 10) = 0
x = 20, -10
This system of equations has no solution, the 2 lines will never cross
A.) We know, sum of the complimentary angles is equal to 90.
So, Equation: 15 + x = 90
B.) Solving: 15 + x = 90
x = 90 - 15
x = 75
In short, Your Answer would be 75
Hope this helps!
