Answer: 2(x + 4)
Explanation: If you're asked to factor a polynomial,
the first thing you want to look for is the greatest common factor
for the terms that are involved.
The greatest common factor of 2x and 8 is 2.
So a 2 can factor out.
Inside the parenthses, we have each term divided by
the 2 that factored out of the polynomial.
So we have 2(x + 4).
Answer:
The graph of a quadratic function is a U-shaped curve called a parabola.
Step-by-step explanation:
Answer: 2/7
Step-by-step explanation:
You subtract the y intercepts and put it over the x intercepts
2-(-2)=4 and 9-(-5)=14 so it is 4/14 which sinplifies to 2/7
Y (9 + 2y)
= y (9) + y (2y)
= 9y + 2y²
= 2y² + 9y
Answer:
parallel
Step-by-step explanation:
The "work" is to recognize that both equations describe horizontal lines. All horizontal lines on the Cartesian coordinate grid are parallel.
_____
<em>Additional comment</em>
y = constant . . . . . a horizontal line (y=0 is the x-axis)
x = constant . . . . . a vertical line (x=0 is the y-axis)
__
If you wanted to go to the trouble, you could compare the equation ...
y = constant
to the slope-intercept form ...
y = mx +b
Your comparison would note that m=0. That is, the slope is zero, so the line is horizontal. All lines with the same (zero) slope are parallel.
