Altogether Katrina and her seven friends equal eight. Eight divided by four is two cookies. The answer is 2.
Answer:
p = 1.5 and q = 9
Step-by-step explanation:
Expand the right side then compare the coefficients of like terms on both sides, that is
4(x + p)² - q ← expand (x + p)² using FOIL
= 4(x² + 2px + p²) - q ← distribute parenthesis
= 4x² + 8px + 4p² - q
Comparing coefficients of like terms on both sides
8p = 12 ( coefficients of x- terms ) ← divide both sides by 8
p = 1.5
4p² - q = 0 ( constant terms ), that is
4(1.5)² - q = 0
9 - q = 0 ( subtract 9 from both sides )
- q = - 9 ( multiply both sides by - 1 )
q = 9
The answer would be 3 & -3 because
-3 |-3| and 3 |3|
Answer:
A
Step-by-step explanation:
You are given the table
This table represents a linear relationship between time and water leaked, because
The linear function has the equation
Find m and b:
So,
Find the x-intercept:
Hence, point (7,0) is x-intercept with the meaning x=7 is the time it takes to empty the water in the pool
