Answer:
F.
Step-by-step explanation:
Find how much interest she will earn from bank A:
100% = 550
1% = 550 ÷ 100 = 5.5
2.25% = 12.375
Find how much interest she will earn from bank B:
900 - 550 = 350
100% = 350
1% = 350 ÷ 100 = 3.5
3% = 3.5 x 3 = 10.5
Find out how much money she will earn from both banks of their interest:
10.5 + 12.375 = 22.875
Find out how much money she will earn from both banks of their interest in 2 years:
22.875 x 2 = 45.75
Find out how much she earns from both banks including interest:
900 + 45.75 = 945.75
(Final answer)
1 pound of rice costs $3.45
1.2 pounds of rice costs x
Set up the proportion
1 / 1.2 = 3.45 / x Cross Multiply
x = 1.2 * 3.45 Combine
x = $4.14 Answer
This equation has no solution where 'a' and 'b'
are both non-zero real numbers.
You said 2a + 2b = 2a
Subtract 2a from each side: 2b = 0
'b' must be zero.
And it doesn't matter what the value of 'a' is.
As long as b=0, 'a' can be any number.
Step-by-step explanation:
y — yı = m(x – xı) equation of a line
Points A(1,3) and B(2,1)
Slope (m) = (y2 – y1) / (x2 – x1)
(1 –3) / (2 – 1)
–2/1
–2
Thus, y –3 = –2 (x – 1)
y – 3 = –2x + 2
y –3 + 3 = –2x + 2 + 3
y = –2x + 5
