Answer:
8 and - 2
Step-by-step explanation:
let x be the larger number and y the smaller , then
x = 5y + 18 → (1)
3x + 4y = 16 → (2)
substitute x = 5y + 18 into (2)
3(5y + 18) + 4y = 16 ← distribute parenthesis and simplify left side
15y + 54 + 4y = 16
19y + 54 = 16 ( subtract 54 from both sides )
19y = - 38 ( divide both sides by - 19 )
y = - 2
substitute y = - 2 into (1)
x = 5(- 2) + 18 = - 10 + 18 = 8
then larger number is 8 and smaller is - 2
Answer:
Step-by-step explanation:
Answer:
11 seconds
Step-by-step explanation:
If the height h(t) of the sunglasses after t seconds is given by the polynomial function
h(t)=-16t²+1936
The sunglasses will hit the ground when the height h(t)=0
h(t)=-16t²+1936=0
-16t²+1936=0
-16t²=-1936
t²=1936/16=121
t=√121=11 seconds
The Sunglasses will hit the ground 11 seconds after it is dropped by the pilot.
160 i believe. to find the area of a triangle act like its a square and divide in half. for squares multiply base by height.
take the area of each shape and add it up
