Answer:
-q^2 -q + 72
Step-by-step explanation:
(9+ q)(8-q)
=9(8-q)+ q(8-q)
=72 - 9q +8q -q^2
= -q^2 -q + 72
Answer:
4,600
Step-by-step explanation:
To solve this problem, we need to multiply add 15% of 4,000 back to 4,000.
First, change 15% into a decimal:
15% ->
-> 0.15
Next, multiply 4,000 by 0.15:


The last step is to add the 600 back to 4,000:

The population of Smallburg the following year was 4,600.
Answer:
y= -9x+14
Step-by-step explanation:
the equation of a straight line is y=mx+c
m is the slope
And we are given a y and x term
So we substitute these into the equation:
5= -9(1) + c
rearragne to find c
14= c
so the full equation is:
y= -9x+14
280 x (1-0.73)
=280 x 0.37
= £103.60
£280 decreased by 73% is <span>£280 multiplied by 37%.
