D(y) is a linear function. Linear function's domain are all real numbers
Answer:
30 years old
Step-by-step explanation:
Let the two ages be A and C.
Then C = (1/2)A, and A = C + 15.
Substitute C + 15 for A in C = (1/2)A:
C = (1/2)(C + 15), or 2C = C + 15.
Then C = 15, and A = C + 15 becomes A = 15 + 15, or A = 30.
Answer:
m∠RMS = 20°
Step-by-step explanation:
Find ∠RMS and look at the two values it crosses.
∠RMS crosses through 180 and 160.
Find the difference between the two values to get the measure:
180 - 160 = 20°
So, m∠RMS = 20°
(Its also an acute angle.)
The pythagorean theorem states that a^2+ b^2=c^2.
Final answer: None of the above
