Answer:
Step-by-step explanation:
We have the expression
and we must factor it
Note that the expression has no independent term
Then we can factor the expression by taking the variable 4x as a common factor
Finally the factored form of is
Answer:
480 bread rolls
Step-by-step explanation:
For 8 muffins, 6 bread rolls are sold.
This implies for every muffin, bread rolls are sold.
Hence for 640 muffins, they sold 640 ×
= 480 bread rolls.
Answer:
7
Step-by-step explanation:
The average rate of change here, since this is not a line, is the slope of the secant line that is connecting those 2 points. We can find that average rate of change by finding the y coordinates that go with each of those x coordinates and then applying the slope formula. For g(0):
Anything raised to the power of 0 is 1, so we have then:
g(0) = 3(1) - 6 so
g(0) = -3 and the coordinate pair is (0, -3)
For g(3):
so
g(3) = 18 and the coordinate pair is (3, 18).
Now we plug those into the slope formula:
So the averagee rate of change, which is also the slope, between those 2 points is 7
