Solution for F(x)=6x^2-900 equation:
<span>Simplifying
F(x) = 6x2 + -900
Multiply F * x
xF = 6x2 + -900
Reorder the terms:
xF = -900 + 6x2
Solving
xF = -900 + 6x2
Solving for variable 'x'.
Reorder the terms:
900 + xF + -6x2 = -900 + 6x2 + 900 + -6x2
Reorder the terms:
900 + xF + -6x2 = -900 + 900 + 6x2 + -6x2
Combine like terms: -900 + 900 = 0
900 + xF + -6x2 = 0 + 6x2 + -6x2
900 + xF + -6x2 = 6x2 + -6x2
Combine like terms: 6x2 + -6x2 = 0
900 + xF + -6x2 = 0 </span>
6x - 7 = 35
6x = 35 + 7 <em> (add 7 and then divide by 6)</em>
6x = 42
x = 42/6
x = 7
Answer:
x + y = 6
Step-by-step explanation:
Standard Form:
y - y1 = m(x - x1)
In this question, the coordinate is (1, 5) with a slope of -1 (the slope is the same as street 1 since street 2 is going to be parallel.
Insert the coordinate and slope into standard form and you'll get this:
y - 5 = -1 ( x - 1 )
y - 5 = -x + 1
y = -x + 6
y + x = 6
