Answer:
45
Step-by-step explanation:
The 45° complement is the angle that constitutes a right angle (90°) when added to 45 .°.
90 - 45 = 45
Answer:
k = 0
Step-by-step explanation:
<u>Explanation</u>:-
given straight line equation is k x+(k+1)y=2......(1)
The point A(2,2) lies on the equation is
substitute x = 2 and y=2
k(2) + (k+1)(2) =2
now simplify 2 k+2 k+2 = 2
subtracting '2' on both sides , we get solution is
4 k +2 -2 = 2-2
4 k =0
k = 0
Answer:
1 a 2 b 3 d 4 c 5 c 6 b
Step-by-step explanation:
.9x-2.1+.9=.2(5-x) multiply .2(5-x)
.9x-2.1+.9=1-.2x; add - 2.1 + .9
.9x-1.2=1-.2x; cancel -2x by adding it by itself and add it on the .9x
1.1x-1.2=1; cancel -1.2 by adding it by itself and add it on the 1
1.1x=2.2; divide 1.1 so it can be canceled and then on 2.2
x=2 :)
C. since:
coefficients: 18/-12 = -3/2
exponents of a: -2-(-4)=2
exponents of b: 5-(-6)=11
