Y2-y1 / x2-x1
so, 3-1 =2 and 4-3=1
2/1 is 2
2208 rounded to the nearest hundred would be 2200 because the number beside 2 is 0 and that makes the number stay the same and everything after it would be 0 so the answer is 2200
Answer:
ok so I think it's -3:3
Step-by-step explanation:
hopefully thats right
D because y (time spent) = 50 × x (distance travelled)
225÷4.5=50
x÷y=50
Answer:
x = ± 1
Step-by-step explanation:
Given
3(x² - 4) + 7 = - 2 ( subtract 7 from both sides )
3(x² - 4) = - 9 ( divide both sides by 3 )
x² - 4 = - 3 ( add 4 to both sides )
x² = 1 ( take the square root of both sides )
x² = ±
= ± 1
Thus
x = - 1, x = 1
