Answer:
Thats correct.
Step-by-step explanation:
Answer:
y + 4 = (x - h)^2
Step-by-step explanation:
"vertex form" is y - k = a(x - h)^2. Here, the vertex (h, k) is (-3, -4), and so we have:
y + 4 = a(x + 3)^2. To find the coefficient a, substitute -1 for x and 0 for y:
0 + 4 = a(-1 + 3)^2, or
4 = a(2^2). Thus, a = 1, and the desired equation is
y + 4 = (x - h)^2
Applying parallel line postulate twice
36degree=3x degree +2y degree
126 degrees=12 x degree + 2y degree
So, the two equations are:
3x + 2y = 36
and
12x + 2y = 126
Eliminate x to solve for y
-(3x + 2y)= -(36)
-3x - 2y = -36
Combine the equations
(-3x - 2y)+ (12x + 2y) = (-36) + (126)
-3x -2y + 12x + 2y = -36 + 126
9x = 90
x = 10
Plug value of x back into to the equations to solve for y
3(10) + 2y = 36
30 + 2y = 36
2y =6
y = 3
Optional
Plug x into the other equation to check for error
12(10) +2y = 126
120 + 2y =126
2y = 6
y = 3
Explanation:
The slope-intercept form of a line is:
y=mx+b
where:
m is the slope of the line
b is the y-intercept
We are given that m=4 and the line passes through (7,2).
∴2=4⋅7+b
2=28+b
b=−26
Therefore the equation of the line is:
y=4x−26
graph{y=4x-26 [-1.254, 11.23, -2.92, 3.323]}
700/200=7/2 because devide by 100 and then=3 1/2 and half is .5 so=
3.5
