Answer:
Answer c:
Step-by-step explanation:
Hi there!
Let´s start writting the formula
If we multiplicate both sides by (x₂ - x₁):
Then if we add y₁ to both sides of the equation:
Then, the right answer is the answer c)
Have a nice day!
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)
The answer would be 129.85
53 x 1.45 = 76.85
76.85 + 53 = 129.85 dollars
