Answer:
Domain: {-1, 0, 1, 2, 4}
Range: {-5, -4, -3, -1, 3, 5}
Step-by-step explanation:
The domain is all the x values.
The range is all of the y values.
Answer:
Justin bought his truck new for $32,000. Its value decreases 9.0% each year. Choose the letter for the best answer.
5. Which function represents the yearly value of Justin's truck?
A f(t) = 32,000(1 + 0.9)^t
B f(t) = 32,000(1 - 0.9)^t
C f(t) = 32,000(1 + 0.09)^t
<u>D f(t) = 32,000(1 - 0.09)^t
</u>
6. When will the value of Justin's truck fall below half of what he paid for it?
F In 6 years
<u>G In 8 years
</u>
H In 10 years
J In 12 years
Step-by-step explanation:
first we represent the unknowns using variables:
let x = measure of angle 4
let 3x+4 = measure of angle 3 (from the second statement)
then we set-up the equation. since the angles form a linear pair, their sum is equal to 180 degrees. therefore,
x + 3x + 4 = 180
4x + 4 = 180
4x = 176
x = 44 degrees (measure of angle 4)
3x + 4 = 136 degrees (measure of angle 3)
3400-480-2500=420
The answer is 420 millilitres
X= 10
I= 1
10+10+1+1+1= 23
I hope this helps!
