One number is equal to two times a second number. two times the first number plus two times the second number is 24. if you let x stand for the first number and y for the second, what are the two numbers?
a. x = 24, y = 12
b. x = 12, y = 6
c. x = 8, y = 4
d. x = –24, y = –12

Aprojectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. after how many seconds does the projectile take to reach its maximum height?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
