Answer:
Step-by-step explanation:
The given functions are
and
By the algebraic properties of functions:
We just have to substitute to obtain:
The first choice is correct.
Answer:
see explanation
Step-by-step explanation:
∠TRV = ∠SRW ( vertical angles ), hence
2x + 15 = 85 ( subtract 15 from both sides )
2x = 70 ( divide both sides by 2 )
x = 35
Hence
∠VRU = 2x + 10 = ( 2 × 35) + 10 = 70 + 10 = 80°
and
∠URW + ∠VRU + ∠SRW = 180 ( sum of angles in a straight line ), thus
∠URW + 80 + 85 = 180
∠URW + 165 = 180 ( subtract 165 from both sides )
∠URW = 15°
Look carefully at the point where the 2 lines intersect. From that point, look straight down to the x-axis; you'll see that the x-value there is 50. Similarly,
starting at the intersection, look straight left to the y-axis; the y-value there is 11.
Thus, the coordinates of the intersection (i. e., the solution) are found in (50,11).
Answer:f(3)=26,f(6)=215
Step-by-step explanation:
f(x)=3^x-1
f(3)=3^3-1
f(3)=3x3x3-1
f(3)=27-1
f(3)=26
f(6)=6^3-1
f(6)=6x6x6-1
f(6)=216-1
f(6)=215
Answer: n = -198
Step-by-step explanation: To find n we need to work backwards, so we need to multiply -11 x 18 to get -198. So n would be -198.
