Answer:
A, because before x it says -13 which is the slope and 1 because it’s says plus one not minus one
Step-by-step explanation:
Answer:
<em>y</em> = (x - 4)(x + 2)
Step-by-step explanation:
Quadratic Formula:
- <em>ax</em>² + <em>bx </em>+ <em>c</em> = 0
Substitute 1 for <em>a</em>, -2 for <em>b</em>, and -8 - <em>y</em> for <em>c</em> in the quadratic formula.
Answer:
x = 1, y = 2
Step-by-step explanation:
-5x + y = -3, we get y = 5x - 3.
Then plugs into the second equation, we get
-x - 5 (5x-3) = -11.
-x - 25x + 15 = -11,
-26x = -26
x = 1,
plugs x = 1 to y = 5x - 3, we get y = 2.
Answer:
the answer is (c)
Step-by-step explanation:
-(-1)-13= 1-13=-12
Answer:
Step-by-step explanation:
1. Perfect square trinomials, are 2nd degree polynomials, of the form so that , which can be written as perfect squares.
2. For example
3. Thus are perfect square trinomials.
4.
5. In the first case -b=20, so b=-20. In the second case, -b=-20, so b=20.
6. b∈{-20, 20}
