Answer:
x=9 y=5
Step-by-step explanation:
Let -4x+9y=9 be function 1 while x-3y=-6 be function 2
function 1 plus 4 times function 2
-4x+4x+9y-12y=-15
Simplify
-3y=-15
Divide each side by -3
y=5
Substitude y=5 into function 2
x-3(5)=-6
x-15=-6
add 15 to each side
x=9
The delivery route took 4 hours and 15 minutes.
Because 9:50 + 4 hours is 1:50
1:50 + 15 minutes is 2:05
Hope this helps! Have a great rest of your day :)
Answer:
f(2)= 5
Step-by-step explanation:
Given f(x) = -x² + 1
f(2) = -2² + 1 = 4 + 1 = 5
f(2) means the value of x = 2
Hence we substitute the value of X into f(x) = -x² + 1
