Ax + z = aw - y....subtract aw from both sides
ax - aw + z = -y....subtract z from both sides
ax - aw = -y - z....factor out a on the left side
a(x - w) = -y - z...divide both sides by (x-w)
a = (-y - z) / (x - w)
Answer:
x = 4
Step-by-step explanation:
Using the sine ratio on right triangle KJL
and the exact value sin30° = 
sin30° = 
= 
= 
= ( cross- multiply )
2JL = 8
( divide both sides by 2 )
JL = 4
---------------------------------------------------------
Using the sine ratio in right triangle JLM
and the exact value sin45° = 
sin45° = 
= 
= 
= ( cross- multiply )
x × = 4 ( divide both sides by
x = 4
5/6= c/9
Cross mutiple. 5* 9= 45 . c*6
45= 6c
divide by 6 for 45 and 6c
45/6= 6c/6
45/6= c
Reduce 45/6. Divide by 3
45/3, 6/3
15/2= c
Answer: c= 15/2 or in decimal form , c= 7.5
If complex coefficients are allowed, the answer is 3.
If the polynomial must have real coefficients, then each complex root comes as a pair of complex conjugate roots.
Root -5 is real, so that is 1 root, and degree 1.
Root 1 + 4i is complex, so it must come with its complex conjugate, 1 - 4i. This adds 2 roots to the polynomial, and now we're up to degree 3.
Root -4i is also complex. It also must come with its complex conjugate, 4i. That adds two more roots, and the degree is 5.
Answer: The least possible degree is 5 with real coefficients.
Answer:
Step-by-step explanation:
y = -14, m = -2, b = -2
-14 = -2(x) + -2
-14 = -2x + -2
-12 = -2x
Divide by -2.
x = 6
