Answer:
1. x^2 +2x -24 = 0
2. x^2 -7x +10 = 0
Step-by-step explanation:
If you look at the factored and expanded forms of a quadratic with solutions p and q, you see ...
(x -p)(x -q) = x^2 -(p+q) +pq
The x-term coefficient is the opposite of the sum of solutions.
The constant is the product of solutions.
This knowledge lets you write down the standard form equation with no particular effort.
1. x^2 +2x -24 = 0
2. x^2 -7x +10 = 0
3c(5+c) -2(3c-7)
15c+3c^2-6c+14
9c+3c^2+14
Solve the equation for y
x-3y= -18
-3y = -18-x
now, divide both sides with -3
y = (-18-x)/-3
y = 6 +x/3
your slope is 1/3
and y-intercept is 6
Step-by-step explanation:
According to the given diagram,
By exterior angle property,
x=46°+30°
x=76°
