Answer:
The Y-intercept or number after the + or - sign is what you start with then you use rise/run rise=the y value and run = x value to use the constant
Step-by-step explanation:
1. 7x(x + 3)
7x(x) + 7(3)
7x² + 21
2. (7x + 1)(x + 3)
7x² + 21x + x + 3
7x² + 22x + 3
3. (x² + x)²
(x² + x)(x² + x)
x^4 + x³ + x³ + x²
x^4 + 2x³ + x²
It is choice B
i hope that helps
Infinite solutions because
3x + 1 = 3x -3 +4
3x + 1 = 3x + 1
(Those are the same if you couldn't tell)
Answer:
These are corresponding angles, which means that there angle measurements would equal the same. Corresponding angles have the same relative position at intersections (as shown by x and 110).
1) Angle Pair: Corresponding Angles
2) By using the definition of Corresponding Angles, we can derive that x = 110.
