Answer:
the firtst part is 2 2
c11 = -1
c12 = 3
c21 = 3
c22 = -3
the next part is
d11 = 0
d12 = 6
d21 = 1
d22 = -4
Step-by-step explanation:

So we would begin this problem with the simple interest equation:
A=P(1+rt)
the t (time) is in years so we divide 120 by 365
Then we can plug in the information we already know
A=8000(1+.095(.33))
A=8000(1.03135)
A=8250.8
So in total, it is $8250.80
Step-by-step explanation: Let
Let
y
be the total fee, and
x
the number of months.
Equation 1:
y
=
50
+
55
x
Equation 2:
y
=
200
+
45
x
Solve the system for
x
and
y
:
50
+
55
x
=
200
+
45
x
10
x
=
150
x
=
15
y
=
200
+
45
(
15
)
y
=
875
∴
The total amount paid to both gyms is equal after
15
months and will be
$
875
.
Hopefully this helps!
2^2 , or 4
since the exponents have the same base, we can subtract the exponent of the numerator by the exponent in the denominator.
So 2^-3 - 2^-5 = 2^(-3-(-5)) = 2^2
The new exponent is 2 because -3-(-5) is equal to 2.
Step-by-step explanation:
AO = DO
2x+3 = 5x
3 = 5x-2x
3 = 3x
x = 1
DO = 5(1)=5cm
AC = 2×5 = 10cm
BC =√10²-8²
= √100-64
=√36
=6 cm
therefore, the perimeter of the rectangle
= 2×(8+6) = 2(14) = 28 cm
