Answer:
12x^2 + 8y -4
Step-by-step explanation:
(7x^2+3y-4) + (5x^2+5y)
= 12x^2 + 8y -4
Answer:
P(w) = 9w+5
Step-by-step explanation:
You see every week there is an increase of 9, and it starts at 5. That's all you need to know for a linear equation.
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:
<h3>P=6s</h3>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- a linear function is function with two variables one dependent another one is independent
<h3>let's solve:</h3>
since we can see what linear function is
the second condition is the best fit
<h3>The perimeter of a square, P, where the length of each side of the square is B represented by s</h3><h3>(P = 4s)</h3>
therefore
our answer is b
