Answer : 4 & 5
Explanation :
4x-5/8 >-10 + 3x |multiply by 8
4x-5> -80 + 24x. | minus 4x , add 80
-5+80 > 24x -4x
75> 20x. |divide by 20
3.75 > x
So x is greater than 3.75 therefore 4 and 5 are the answers
So investment is $140 and interest is 3% per yea
yo convert % to number 3/100 = .03
so for one year. $140 x .03 = $4.20/year
in two years you have $4.20+$4.20 =$ 8.40!
Answer is $8.40 or 2 years
Answer:
-2x^2 + 3x -1
Step-by-step explanation:
y = ax^2 + bx + c
(0,-1):
-1 = a(0)^2 + b(0) + c
-1 = 0 + 0 + c
-1 = c
(1,0):
0 = a(1)^2 + b(1) + c
0 = a + b + c
(2,-3):
-3 = a(2)^2 + b(2) + c
-3 = 4a + 2b + c
Replace c with -1
0 = a + b -1
1 = a + b
-3 = 4a + 2b -1
-2 = 4a + 2b
-1 = 2a + b
Solve:
2a + b = -1
-1a - b = -1
a = -2
2a + b = -1
-2a -2b = -2
-b = -3 divide both by -1: b = 3
a = -2; b = 3; c = -1
y = ax^2 + bx + c or y = -2x^2 +3x -1
Answer:
2
Step-by-step explanation:
(12^0) + (((1.25 x 4) + 3) * ((1/2)^3)) = 2
hope this helps! :)
