Answer:
(x-8) (x+2)
Step-by-step explanation:
x^2 – 6x – 16
Factor
What 2 numbers multiply to -16 and add to -6
-8 *2 = -18
-8+2 = -6
(x-8) (x+2)
Answer:
-3/2, -1
Step-by-step explanation:
Each coordinate contains one
value and one
value,
.
If we work out the midpoint of each of these individually, it makes it much easier to find the midpoint of the line.
Let's take the
values first. Our first
value is -4 and our second
value is 1. Imagine the integers between -4 and 1 laid out in a sequence:

If you take the middle value of this sequence, you get the midpoint of the
values.
In this case, the middle is between values -2 and -1, leaving us with a midpoint of -1.5. This as a fraction is
.
Now let's look at the
values. Our first
value is 2 and our second
value is -4. Again, let's imagine those numbers laid out in a sequence:

Here, the middle of these values is -1, and this is the midpoint of the
values.
So if we put these two values in a coordinate, we get the midpoint of the line.
In this case, we get
.
Answer:
BCD is the outer angle of triangle ABC
=> BCD = ABC + BAC
<=> 150⁰ = ABC + 118⁰
=> ABC = 150⁰ - 118⁰
<=> ABC = 32⁰
y = 2x + 4
in standard form is
2x - y = -4
Second equation is
x + 2y = 8
Those aren't parallel.
Answer: exactly one solution
Let's solve,
x +2(2x + 4) = 8
5x + 8 = 8
5x = 0
x = 0
y = 2x + 4 = 4
Solution is (0,4)
