Step-by-step explanation:
Question 2:
A relation is a function if every different x-value has a y-value. Since this relation has two outputs for x = 4 (1 and 9), it is NOT a function.
Question 3:
Plug the three points listed (-1, 0, 1) into the function and get their outputs. This will be the range.
f(x) = 2x + 4
Plug in -1.
f(-1) = 2(-1) + 4
f(-1) = -2 + 4
f(-1) = 2
f(x) = 2x + 4
Plug in 0.
f(0) = 2(0) + 4
f(0) = 4
f(x) = 2x + 4
Plug in 1.
f(1) = 2(1) + 4
f(1) = 2 + 4
f(1) = 6
This makes the range {2, 4, 6}.
A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
Answer:
about 5.3
Step-by-step explanation:
783 divided by 5 would be 156.6. I'm not sure if that's what you meant. But dividing it the way you said comes into a big decimal
