Answer:
First answer choice
Step-by-step explanation:
Answer:
-4x+y=7
Step-by-step explanation:
lets say you have y=4x+7 (linear equation)
to conver it to standard form you've got to make it Ax+By=C
so you minus the 4x and you should have -4x+y=7 for your standard form
No because fifteen minus nine is six, so Tyler read six more pages than Ann.
Answer:
all real numbers greater than or equal to -1
Step-by-step explanation:
In order to solve this problem we need to know the vertex and the direction its pointing.
First we expand,
x^2-6x+8
To find the x value of the vertex we use this formula (-b/2a).
-(-6)/2(1) = 3
Now we plug 3 in the equation to get the y value,
(3)^2 - 6(3) + 8 = 9 - 18 + 8 = -1
The vertex is (3,-1)
We know the graph points up because x^2 is positive
The vertex is the lowest point, so we now know that -1 is the starting range and if the graph is pointing up, that means all values greater than -1.
This leads to our answer all real numbers greater than or equal to -1.
Answer:
A
Step-by-step explanation:
When X is less than -1, positive parabola.
