Answer:
y = 42
Step-by-step explanation:
18 - y = -24
18 + 24 - y = 0
18 + 24 = y
18 + 24 = 42

Answer:
4
hours
Step-by-step explanation:
he was gone for 5 
hours, he spent 
an hour driving.
5 - = 4 hours at work.
J = 14
J = 1/2S + 4 1/2
14 = 1/2S + 9/2....multiply everything by 2 to get rid of fractions
28 = S + 9
28 - 9 = S
19 = S
check...
14 = 1/2S + 9/2......S = 19
14 = 1/2(19) + 9/2
14 = 9 1/2 + 9/2
14 = 19/2+ 9/2
14 = 28/2
14 = 14 (correct)
so the sister is 19 <===
Answer:
the answer is 5 because thats the varible
Step-by-step explanation:
We are given with the equation y"+ 9 y = t^2 * e^3 t + 6 and asked to determine the general solution to this equation. we convert the equation into r^2 + 9 = 0. The solution to this equation is r = +/- 3i. This solution converted to trigonometric function is equivalent to <span>y</span>= <span>C1 </span>cos3t + <span>C2 </span>sin<span>3t. </span>
