Steps of adding -6 + 4 using number line are as following:
1) Draw a number line by ranging from -10 to +10.
2) Point out -6 on the number line.
3) Because 4 is added to -6 on the number line, please move 4 number right to -6 on the number line. We always go right in addition and go left in subtraction on the number line.
4) The number we reach 4 on right side would be our final sum.
5) From the number we can clearly see that moving 4 number on right to -6, we get -2.
So, final answer is -2.
Answer:
a = 4, p = 2, q = - 1
Step-by-step explanation:
Expand the right side of the identity, then compare the coefficients of like terms with those on the left side.
a(x - p)² + q ← expand (x - p)² using FOIL
= a(x² - 2px + p²) + q ← distribute parenthesis
= ax² - 2apx + ap² + q
Compare coefficients of x² term
a = 4
Compare coefficients of x- term
- 2ap = - 16, that is
- 2(4)p = - 16
- 8p = - 16 ( divide both sides by - 8 )
p = 2
Compare constant terms
ap² + q = 15 , that is
4(2)² + q = 15
16 + q = 15 ( subtract 16 from both sides )
q = - 1
Thus a = 4, p = 2, q = - 1

Answer: $6.99
Step-by-step explanation: each minute is 20 cents and the connection fee is .99 cents.
30x.20= 6.00
6.00 + .99 = $6.99
