Answer:
See below
Step-by-step explanation:
to find the slope of a line you need to use the formula y1-y2/x1-x2
2. the points are (3,2) and (1,-2)
y1-y2 = 2--2 = 4
x1-x2 = 3-1 = 2
4/2 is the same as 2
3. (1,4) and (2,1)
4-1=3
1-2=-1
3/-1 = -3
the slope is -3
4. (6,5) and (3,1)
5-1 = 4
6-3 = 3
4/3
the slope is 4/3
12 mins each
60 divided by 5 equals 12
Answer:
-11.3
Step-by-step explanation:
You start off at -11 and count down and it ends up at -11.3
6.5X + 9(30) = 8(30+X)6.5X +270 = 240 + 8X270-240 = 8X-6.5X1.5X = 30X = 30/1.5 =20 ounces of $6.50 alloy9 is within 1 of 86.5 is within 1.5 of 81.5 is 3/2 of 130 is 3/2 of 20You know you need more of $9 alloy since it's closer to $8You need exactly 3/2 or 1.5 times more of the $9 alloy30 is 1.5 times 20
Answer:
x = 2
Step-by-step explanation:
5x + (x + 12)
6x = 12
x = 2
