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:
y=6x+5
Step-by-step explanation:
y-2=6x+3
y=6x+3+2
y=6x+5
Answer:
Transitive property
But it looks like substitution.
Step-by-step explanation:
Answer:
m = 1
Step-by-step explanation:
We can use the x & y intercepts.
Rise = 2
Run = 2
m = Rise/Run = 2/2 = 1
