Graph?
well
for
|a|>b solve
a>b and a<-b
|4w+1>11
solve
4w+1>11 and 4w+1<-11
minus 1 both sides
4w>10 and 4w<-12
divide both sides by 4
w>5/2 and w<-3
graph the points -3 and 2.5
shade outside
not including
2.
union means include all common to both
so
2. 1,2,3,4,6,8,9
3. 1,2,3,4,5,7,10
4. interseciton so only ones common to both, so 4
5. null set (empty)
Answer:
y = 4x - 1
Step-by-step explanation:
The line has a slope of 4.
And passes through the point (1,3)
Taking another point (x,y) on the line;
= 4
y - 3 = 4x - 4
y = 4x - 4 + 3
y = 4x - 1
48-10=x x=38
38x2= 76
so basically his weight is 48, which is ten more than his fathers weight, so you subtract ten from 48, giving you 38. 38 is only half the father's weight, so you double it and get 76.
Answer:
271.2 meters

Evaluate: x⁻² for x = -3
The negative sign of the exponent signifies that the number is a denominator with 1 as the numerator.
The number is in negative form, it becomes a positive number because it is squared. negative number times negative number equals positive number.
x⁻² where x = -3 ⇒⇒ -3⁻² = 1/-3² = 1/9
