I think the on in the top right is the answer.
Answer:
x=18 y=2.5
Step-by-step explanation:
Step 1- 11x+10=9x-26
-9x -9x
Step 2- 2x+10=-26
-10 -10
Step 3- 2x/2=36/2
Conclusion- x=16
Step 1- 7y+5=9y
-7y -7y
Step 2- 5/2=2y/2
Conclusion- y=2.5
Answer:
6.6 cm
Step-by-step explanation:
The tangent function relates the 35° angle, the adjacent side 12 cm, and the unknown opposite side, x.
We can write tan 35° = opp / adj = x / (12 cm)
Multiplying both sides by 12 cm isolates (solves for) x:
(12 cm)(tan 35°) = x Note that 35° is equivalent to 0.6109 radians.
Thus, x = (12 cm)(0.5484) = 6.58 cm, or 6.6 to the nearest tenth.
You plug 7 in for x
Therefore, f(7)=7-2=5
So f(7)=5
