Answer:
70 minutes
Step-by-step explanation:
if her pace for 1 mile is 10
Answer:
-1 and -2, or 9 and 10
Step-by-step explanation:
If x is the smaller integer:
x (x + 1) = 14 + 4 (x + x + 1)
x² + x = 14 + 4 (2x + 1)
x² + x = 14 + 8x + 4
x² − 7x − 18 = 0
Factor using AC method:
(x − 9) (x + 2) = 0
x = -2 or 9
x is the smaller integer, so the larger integers are -1 and 10. Check each pair of solutions.
-1 and -2:
(-2) (-1) = 14 + 4 (-2 + -1)
2 = 14 + 4 (-3)
2 = 2
9 and 10:
(9) (10) = 14 + 4 (9 + 10)
90 = 14 + 4 (19)
90 = 90
Both solutions work.
Answer:
A. {x | x < 8}
Step-by-step explanation:
First, we divide both sides by 3.
3(x - 2)/3 < 18/3
Then simplify.
x - 2 < 6
Lastly, add 2 to both sides.
x - 2 + 2 < 6 + 2
<u>x < 8</u>
If you divide 1,200 and 40 it equals 30 then you take 250 subtract 30 the answer is 220
The pattern of a linear function, is the following:
y = mx + b
Where m is always the slope.
m in this case is -4, hence
The correct answer for your question is -4.
