This is because there is an imaginary 1 in front of the second term that you have to remember to use when combining like terms. </span>

Answer:
(c) 11
Step-by-step explanation:
As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...
x = 4+1 = 5; f(x) = 9+2 = 11
The appropriate choice is f(5) = 11.
D (56.5)
Originally, the train traveled 340 miles in 8 hours
If we use the formula d/t, we'll have 340/8, which is 42.5
If we add 14, then we'll have 56.5, or d
The expression relating the distance and the time is:
velocity = distance / time
We are given the velocity as 12 km/h
Part a:
for t = 3.5 hours
velocity = distance / time
distance = velocity x time
distance = 12 x 3.5 = 42 km
Part b:
for s = 30 km
velocity = distance / time
time = distance / velocity
time = 30 / 12 = 2.5 hours
Answer:
<h2>y = -3</h2>
Step-by-step explanation:
Put x = 1 to the equation 9x + 7y = -12
(9)(1) + 7y = -12
9 + 7y = -12 <em>subtract 9 from both sides</em>
7y = -21 <em>divide both sides by 7</em>
y = -3
