Answer:
k = 6
Step-by-step explanation:
The parabola moved to the left by 6 units. It is important to know that when a problem says (x + 6) it means move to the left and when a problem says (x - 6) it means move to the right.
Extra information:
When a problem is like: f(x) + 7, it means to go UP 7, and f(x) - 7 would be to go down 7. Notice the number is outside the parentheses.

Step-by-step explanation:
Given points,
( -2 , 3) and (4,3)
we know,
slope = y_2 - y_1 / x_2 - x_1
so according to it we got,
→ (3 - 3)/4 - (-2)
→ 0/6
hope this answer helps you dear! take care.
Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.
The factored forms of that is (x + 6) (x - 7).
