The answer is D = 80
D =16t if t= 5 then d = 80
Answer: I’m sorry I can’t figure out what A B and C are but ax=(2,0) and by=(0,4) I believe
Step-by-step explanation:
X intercept (2,0). Y intercept (0,4)
A - 2b = 2 . . . (1)
a + b = 2(b + 3)
a + b = 2b + 3
a - b = 3 . . . (2)
(1) - (2) => -b = -1 => b = 1
From (2): a - 1 = 3 => a = 3 + 1 = 4
Therefore, a = 4 and b = 1
Answer:
7 and 13
Step-by-step explanation:
let the 2 numbers be x and y , x > y , then
x = y + 6 → (1)
(x + y) = y - 2 ( multiply both sides by 4 to clear the fraction )
x + y = 4y - 8 ( subtract 4y from both sides )
x - 3y = - 8 → (2)
Substitute x = y + 6 into (2)
y + 6 - 3y = - 8
- 2y + 6 = - 8 ( subtract 6 from both sides )
- 2y = - 14 ( divide both sides by - 2 )
y = 7
Substitute y = 7 into (1)
x = 7 + 6 = 13
The 2 numbers are 7 and 13
Answer:
x = -46.5
x + 1 = -45.5
Step-by-step explanation:
x + x + 1 = -92
2x + 1 = -92
-1 -1
------------------
2x = -93
---- ----
2 2
x = -46.5
x + 1
(-46.5) + 1
-45.5
