Answer:
they cost 13.86666666666667
Step-by-step explanation:
Answer:
y = 140, x = 159
Step-by-step explanation:
Angle y:
we can find this angle by subtracting 40 from 180, 180-40 = 140 = y
Angle x:
Some measure of an angle plus angle b is equal to 180 degrees: 180-61 = 119
We can now find the measure of the third angle of the triangle: 180-(119+40) = 21
The third angle plus angle x is equal to 180: 180-21 = 159 = x
It's c.
for example:
2*2 +1 = 5
2*4 +1 =9

Answer:
(a, b) = (-2, -1)
Step-by-step explanation:
The transpose of the given matrix is ...
Then the [3,1] term of the product is ...
and the [3,2] term is ...
Both of these terms in the product matrix are 0. We can solve the system of equations by adding these two terms:
(a +2b +4) +(2a -2b +2) = (0) +(0)
3a +6 = 0
a = -2
Substituting for 'a' in term [3,1] gives ...
-2 +2b +4 = 0
b = -1
The ordered pair (a, b) is (-2, -1).
