It would be the second one
Answer:
I only know the first 1 sorry but here is the answer y=-3/4+2
Step-by-step explanation:
3x+4y=8
-3x -3x subtract -3x to get on the right side
4y=-3x+8
/4 /4 /4 divide by 4 on both sides
y=-3/4x+2 since 4 can't go into 3 you leave as a fraction -3/4x
UPDATE: I found the answer to number 4
The answer is y=-11/7x+8
-11x-7y=-56
+11x +11x Add 11x
-7y=11x-56
/-7 /-7 /-7 Divide by -7 on both sides
y=-11/7x+8 Since -7 can't go into 11 you leave as a fraction -11/7x
ANOTHER UPDATE: I found the answer to number 7
-14x+y=7
+14x +14x Add 14x to both sides
y=14x+7 Since y doesn't have a number your answer is as shown
Answer:
Step-by-step explanation:

Answer:
Population in 2050 = 11,369,600,000
Step-by-step explanation:
Given:
Population in 2000 = 6,080,000,000
Rate of increase = 1.26%
Find:
Population in 2050
Computation:
Number of year = 50
Population in 2050 = Population in 2000[1+r]ⁿ
Population in 2050 = 6,080,000,000[1+1.26%]⁵⁰
Population in 2050 = 6,080,000,000[1.87]
Population in 2050 = 11,369,600,000
The falling stone is a certain instant 230 feet above the ground. 3 seconds later it is only 14 feet above. The height that it was dropped is 32 feet. The equation for the answer is;
<span>16<span>t2</span>+<span>h0</span>=230</span>
<span>−16(t+3<span>)2</span>+<span>h0</span>=14</span>
