Answer:
Option A.
Step-by-step explanation:
we have
Simplify the right side of the equation
we know that
so
The expression is
therefore
x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a
Answer: Yes is
Step-by-step explanation: If the scale factor is greater than 1 it is an enlargement of the actual area
Answer:
y=3x+5
y=-2x-1
y=-4x
y=1/2x+2
Step-by-step explanation:
These are linear functions(y=mx+b). m stands for the slope and b stands for the y intercept. After plugging in your slope, you use the coordinates they give you to find the y intercept. To find the y intercept plug in the y coordinate into the y in y=mx+b, and plug in the x coordinate into the same equation.
