Answer:
Step-by-step explanation:
in order to solve this system of equation we would say that let
3x+2y=-8........................................................ equation 1
1 x - y = -1 ........................................................ equation 2
from equation 2
1 x - y = -1 ........................................................ equation 2
x = -1 + y....................................... equation 3
substitute for equation 3 in equation 1
3x+2y=-8........................................................ equation 1
3( -1 + y) + 2y = 8
-3 + 3y +2y = 8
collect the like terms
-3 + 5y = 8
5y = 8 + 3
5y = 11
divide both sides by the coefficient of y
5y/5 = 11/5
y = 2.2
put the value y = 2.2 into equation 3
x = -1 + y....................................... equation 3
x = -1 + 2.2
x = 1.2
therefore th value of x is 1.2 and y is 2.2
Answer:
(2x+5)(-3x+7)
-6x^2-15x+14x+35
-6x^2-x+35
So, the last option is the correct answer.

Answer:
$121
Step-by-step explanation:
A suitable calculator or spreadsheet can tell you the payment amount for the given loan values. The annual interest rate will be 12 times the monthly, rate, or 2.4%. The number of monthly payments in 12 years is 12×12 = 144.
__
A calculator shows the monthly payment will be about $121.
__
If you want to figure this "by hand," the amortization formula is used.
A = Pr/(1 -(1+r)^-t)
where P is the loan amount, r is the monthly interest rate, and t is the number of months.
A = 15100(0.002)/(1 -(1.002^-144)) ≈ 120.789 ≈ 121
The monthly payment would be $121.
Answer:
V=450cm^3
Step-by-step explanation:
l=15cm
w=6cm
h= 5cm
V=lxwxh
V= 15cmx6cmx5cm
V=90cm^2x5cm
V=450cm^3
Hope this helps ❤❤❤❤
The answer would be 25 because if every 2 pieces is one move you would divide 50 by 2.
