Hope this helps!
< 1 and < 2......adjacent angles...because they have a common side and a comon vertex
< 1 and < 2.....complimentary angles....because when added, they equal 90
Answer:
Choice B. log 4^x = log 17
Step-by-step explanation:
Solve 4^x=17
x is in the exponent... so the only operation to bring the x down is the Logarithm
log 4^x = log 17 take log of both sides
then x* log 4 = log 17
and then x = (log 17)/(log 4)
This answer is pretty simple.
Since there are 3 yards of ribbon, and you need to make ____ number of pieces with each 1/4 long
To do this you divide.
3 divided by 1/4
The answer is 12
Step-by-step explanation:
multiplying the 2nd eqn by 9 we get,
9x+9y=81
then,subtracting 1st and 2nd eqn
9x+5y=41
9x+9y=81
- - -
__________
0. -4y=-40
we get y = 10
then we get x=9-y
x=9-10
x= -1
so x is -1 and y is 10
