The parent function was moved left one and down five. It also opened up due to the 1/2
Answer:
45
Step-by-step explanation:
You are given only one space. Note that the term 6 shows up on both sides. Therefore, it is implying that you need to multiply the other two terms together. Do so:
9 x 5 = 45
45 is your answer.
~
A+B = 2X -2
A-B = 4X -8
Add the equations,
2A = 6X - 10
A = 3X - 5
Now, 3X - 5 + B = 2X - 2
B = 2X-3X - 2 + 5
B = 3 - X
Hope this helps!
Answer:
k = ± 4
Step-by-step explanation:
Given
x² - kx + 4 = 0 ← in standard form
with a = 1, b = - k, c = 4
The equation has equal roots, thus the discriminant
b² - 4ac = 0, that is
(- k)² - (4 × 1 × 4) = 0
k² - 16 = 0 ( add 16 to both sides )
k² = 16 ( take the square root of both sides )
k = ± 
= ± 4
