X² - 4x - 77 = 0
( x + 7) ( x - 11)
x + 7 = 0
x - 11 = 0
x = -7
x = 11
Answer:
77.39m + 15
Step-by-step explanation:
To simplify, we add all the common terms among themselves.
We have terms with the unit m and terms without any unit. So we add them among themselves.
59.95m − 30 + 7.95m + 45 + 9.49m
(59.95 + 7.95 + 9.49)m + (-30 + 45)
77.39m + 15
Answer:
-3
Step-by-step explanation:
y - y1 = m(x - x1) m = slope
y - 5 = -3(x - 17) slope = -3
The only thing i can think would work is 6*7=7*6
42=42
Intersection of E and A: E n A = { 8 }
Union of E and A : E U A = { -2, 3, 0, 6 , 8 }
<em><u>Solution:</u></em>
<em><u>The sets E and A are given below:</u></em>
E = { -2, 3, 8 }
A = { 0, 6 , 8 }
<em><u>Find the intersection of E and A</u></em>
Intersection of E and A means that, set containing all elements of E that also belong to A
Therefore,
From sets E and A,
E n A = { 8 }
<em><u>Find the union of E and A</u></em>
union of E and A contains all elements of set E and set A
E U A = { -2, 3, 0, 6 , 8 }
