Answer:
A. Z = 2 + N13
Step-by-step explanation:
Let's solve your equation step-by-step.
0=z2+4z−9
Step 1: Subtract z^2+4z-9 from both sides.
0−(z2+4z−9)=z2+4z−9−(z2+4z−9)
−z2−4z+9=0
For this equation: a=-1, b=-4, c=9
−1z2+−4z+9=0
Step 2: Use quadratic formula with a=-1, b=-4, c=9.
z=
−b±√b2−4ac
2a
z=
−(−4)±√(−4)2−4(−1)(9)
2(−1)
z=
4±√52
−2
z=−2−√13 or z=−2+√13
Answer:
C
Step-by-step explanation:
I did the math
Substitute x for whatever number is on the graph for x then do the math and get the answer for y and see if they are correct for each one.
Answer:
=4/3
Step-by-step explanation:
Step 1
Multiply the denominator by the whole number
6 × 1 = 6
Step 2
Add the answer from Step 1 to the numerator
6 + 2 = 8
Step 3
Write answer from Step 2 over the denominator
8/6
=86
You can also reduce this fraction.
Find the Greatest Common Factor (GCF) of 8 and 6, if it exists, and reduce our fraction by dividing both numerator and denominator by it,
GCF = 2
=8÷2=4
6/2=3
Simplified Solution
=6×1+2/6 =8/6=4/3
hope this helps
you welcome and thanks
Answer:
[8 -6 2 -4].
Step-by-step explanation:
[4 -4 0 0]+[4 -2 2 -4]
= [4+4 -4+-2 0+2 0+-4]
= [8 -6 2 -4]
