28 because a constant is a number that doesn't have x attached to it.hope this helps
PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20
Variable
h and s
Constant
40
PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5
PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40
Answer: D
Explanation:
Point slope form:
(y - y1) = m(x - x1)
Coordinate given = (2,-6)
Slope = 3/5
Thus:
(y -(-6)) = 3/5(x - 2)
y + 6 = 3/5(x - 2)
-1(5x+1)
-5x-1
the (-) in front is just a short way to put (-1)
