Answer:
The answer us B y= -8/7x -18/7
Answer:
x = 1
Step-by-step explanation:
For a quadratic function 
, the axis of symmetry is
.
This comes from using part of the Quadratic Formula for finding zeros of the function:
See the -b/(2a) in the first term? That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function. The axis of symmetry goes through the vertex.
Answer 5 1/4
Step-by-step explanation:
simplify --- 2 5/8 = 21/8
flip 1/2 = 2/1
multiply 21/8 x 1/2
answer = 5 1/4
Answer:
- Line XY contains ray OX and ray OY
- Line XY contains segment YX
- Ray YX exists in the diagram
Step-by-step explanation:
A ray can be named by any pair of points on an infinite line. Point O, X, and Y on the same line can be used to name rays OX, OY, XY, YX, OY, and XO. The first point named is the end point of the ray. The ray goes through the other point and continues indefinitely.
BA can be the name of a line segment, but not a ray. The line shown does not extend from point B beyond point A.
Any segment can be named by its end points in either order.
So, we have ...
- Line XY contains ray OX and ray OY
- Line XY contains segment YX
- Ray YX exists in the diagram
Step-by-step explanation:
Find two numbers that multiply to give ac (in other words a times c), and add to give b.
Rewrite the middle with those numbers:
Step 3: Factor the first two and last two terms separately:
