Answer:
(p, q) is (2, 5)
Step-by-step explanation:
Given the expression
x^2 + 3x - 10
Factorize;
x^2 + 5x - 2x - 10
x(x+5) - 2(x+5)
(x-2)(x+5)
Comparing with (x + p)(x + 9).
x+2 = x+ p
x-x+2 = p
2 = p
p = 2
Similarly;
x+5 = x+q
x-x+5 = q
5 = q
q= 5
Hence (p, q) is (2, 5)
Answer:
The unit price of the problem is that one pack of greeting cards costs $1.85
Step-by-step explanation:
In order to find the unit rate, you have to divide the price by the quantity of the product. So, we will divide 7.40 by 4 so we can see the price of one pack.
7.40 ÷ 4 = 1.85
So, one pack of greeting cards costs $1.85 which is also our unit price.
Answer:
Average rate of change = 2
Step-by-step explanation:
Formula to get the rate of change of a function between x = b and x = a is,
Rate of change = 
We have to calculate the average rate of change between x = -2 and x = 0
From the graph attached,
At x = -2,
f(-2) = 0
At x = 0,
f(0) = 4
Therefore, average rate of change = 
=
= 2
Average rate of change of the given function between x = -2 and x = 0 is 2.
