8k - 8 + 6k
= 14k-8
Hope I helped!
Answer:
The answer is 7
Step-by-step explanation:
We know than Tan45=1
Tanx=opp/adj
tan45=y/(7
)/2
Thus y=7/2
We know by pythagoras theorem that hyp^2=side^2+side^2
=(
+
=(49(2)/4)+(49(2)/4)
=(49/2)+(49/2)
=(98/2)
=49
x=7
Answer:
yes
Step-by-step explanation:
If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that are also functions. Therefore, the inverse is a function.
Answer:
Step-by-step explanation:
the funny lines in the corners of the triangle mean that the angles are the same. Maybe you knew that?
The supplementary angle at the top right is just
180- 17x -23
now you have expressions for each of the 3 angles of the triangle which all add up to 180°
180= 7x + 2 + 7x +2 + 180- (17x -23)
180 = 14x +4 + 180 - 17x +23
180 = -3x +207
3x = 27
x = 9
Add the 2 together
2 2/3 + 2 3/4 you need a common denominator to add fractions
2 8/12 + 2 9/12 = 4 17/12 =
5 5!12 feer
