Answer:
- 7/9
Step-by-step explanation:
-4/9 + (-1/3)
= -(4/9) - (1/3)
= - (4/9 + 1/3)
= - (4/9 + 3/9)
= - [(4 + 3) / 9 ]
= - 7/9
The general line through (a,b) and (c,d) is
(c-a)(y-b)=(d-b)(x-a)
Here that's
(1 - - 5)(y - - 5) = (4 - -5)(x - - 5)
6(y+5)=9(x+5)
6y + 30 = 9x + 45
-15 = 9x - 6y
3x - 2y = -5
Answer: 3x - 2y = -5
We could put that in slope intercept form,
2y = 3x + 5
y = (3/2) x + 5/2
Answer: y = (3/2) x + 5/2
Answer:
Step-by-step explanation:
The CPI increased from 29.6 to 82.4.
The rate of increase, is:
82.4/29.6 = 2.78
Now multiply this rate to the $0.14 price of grapes from 1960.
$0.14 x 2.78 = $0.39
Now to get the amount of increase subtract the new price from the original price:
$0.39 - $0.14 = $0.25 increase.
Answer: 30 ft
Step-by-step explanation:
Cross multiply:
6 : 3.5
x : 17.5
Then divide 105 with 3.5x.
105/3.5x = 30
