Answer:
(3, 1)
Step-by-step explanation:
The midpoint formula is (x1 + x2)/2, (y1 + y2)/2.
(-2, -6) = (x1, y1)
(8, 8) = (x2, y2)
Plug these values into the midpoint formula and solve.
________
(x1 + x2)/2, (y1 + y2)/2
(-2 + 8)/2, (-6 + 8)/2
(3, 1)
2x - 2y = -12
- 2y = -2x - 12
y = x + 6
4x - 7 (x + 6) = -15
4x - 7x - 42 = -15
-3x - 42 = -15
-3x = 27
x = -9
y = -9 + 6
y = -3
(-9 , -3) is the solution
Answer: -9 + 21 = t t = 12°C.
Step-by-step explanation: For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees it will give us our original degrees.
Solve.
-9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12)
12 = t
So, the original degrees in the beginning of the day was 12°C.
Answer: 4 years after the original investment, it is approximately $1,093.
Step-by-step explanation:
Hi, to answer this question we have to apply the simple interest formula:
I = p x r x t
Where:
I = interest
P = Principal Amount
r = Interest Rate (decimal form)
t= years
Replacing with the values given
I = 1000x (2.25/100) x t
- It will triple in approximately 3 years. FALSE
I = 1000x (2.25/100) x 3 =67.5
1000+67.5 = 1067.5
- It will no longer grow after several years: False, it will grow because it has a growth rate.
- 4 years after the original investment, it is approximately $1,093. TRUE
I = 1000x (2.25/100) x 4 =90
1000+90 = $1090
- It will double in approximately 10 years.
I = 1000x (2.25/100) x 10 =225
1000+90 = $1225
