Answer:
(graph attached)
Step-by-step explanation:
rise over run! 2/1 (up two over one to the right) and you know the slope is postive and its y intercept is 2 from the equation.
The equation is a + 9 = 15
Step-by-step explanation:
Let the number be 'a'
Given that,
A number plus 9 is 15
So,
a + 9 =15
a = 15 - 9
a = 6
The equation needed is,
a + 9 = 15
Answer:
(y + 7i)(y - 7i)
Step-by-step explanation:
It cannot be factored using real numbers, but consider
7i × - 7i
= -49i² and i² = - 1
= 49
The factoring as a difference of squares to obtain
y² + 49 = (y + 7i)(y - 7i)
